Thermal transfer printers & Cable identification 361 products

Thermal transfer printers with the markers, tags, sleeves and label stock they print onto, for terminal, cable and device identification. Consumables are listed by tag size and per-sheet or per-box quantity.

Screw connection rail-mount terminals 340 products

Screw-clamp terminal blocks in the standard cross-sections from 1.5 mm² upwards, with end plates, partition plates, jumper bars and end brackets. Screw connection remains the choice where terminals are re-torqued during commissioning or subject to vibration.

Distribution blocks & Busbar supports 249 products

Insulated distribution blocks and busbar support insulators that split a supply from a single incomer to multiple outgoing ways. Rated by current, pole count, and the incoming and outgoing conductor sizes each terminal accepts.

Cable glands & Conduit 244 products

Metric and PG cable glands in nylon, brass and stainless, plus flexible corrugated conduit and its fittings. Gland selection is set by the cable's outer diameter and the required IP rating, and the thread must match the enclosure entry.

Ferrules & terminals 156 products

Bootlace ferrules, insulated and non-insulated crimp terminals, and ring and fork tags for control wiring. Colour-coded by cross-section to DIN 46228; twin-entry ferrules are for two conductors entering one terminal.

Crimping lugs 103 products

Copper tube lugs, links and reducers for terminating larger conductors, tin-plated to prevent corrosion at the joint. Cable cross-section and stud diameter both have to match, and the lug must be crimped with the die set specified for it.

Heat shrink 80 products

Polyolefin heat shrink sleeving in 2:1 and 3:1 ratios, plain and adhesive-lined. Choose a supplied diameter that fits over the largest point and recovers tight onto the smallest; adhesive-lined tubing gives a moisture seal on outdoor joints.

Slotted cable trunking 74 products

PVC wiring duct in the standard panel widths and heights, with matching lids. Slot pitch affects how easily wires break out to a terminal — fill duct to about 60% so future additions and heat dissipation are still possible.

Flexible copper busbar & Braided links 68 products

Laminated flexible busbar and braided copper links for connections that must absorb movement, thermal expansion or vibration. Current rating, length and hole centres define the part; insulated versions save clearance in a tight panel.

Cable ties 56 products

Nylon and stainless steel cable ties in the standard lengths and widths, plus mounts and releasable types. Tensile strength, UV stability for outdoor use, and temperature range are the differences that matter in an industrial installation.

Junction boxes 19 products

Sealed enclosures with terminal blocks for cable joints and field wiring breakouts. IP rating, terminal count and cross-section, and knockout or gland-plate entries are what determine the fit.

Din mounting rail 13 products

TS35 top-hat and G-section rail in the usual lengths, slotted and unslotted, in zinc-plated steel and stainless. Slotted rail cuts and fixes faster; stainless is for corrosive and washdown environments.

Drag-chain cable carriers 13 products

Energy chains that guide and protect cables and hoses on moving axes, preventing the fatigue failure loose cable suffers. Inner height and width, bend radius and travel length are the four dimensions to fix before selecting.

Temperature controllers & Thermocouple sensors 304 products

PID and on/off temperature controllers with matching thermocouple and Pt100 probes. Controller selection covers panel cut-out size, input type, output form — relay, SSR drive or analogue — and alarm count; probes are listed by type, sheath length and process fitting.

Photoelectric sensors 183 products

Through-beam, retro-reflective, polarised retro and diffuse sensors for detecting objects regardless of material. Through-beam gives the longest range and best reliability, diffuse needs no second component; check sensing distance, light source and output type.

Inductive proximity sensors 168 products

Non-contact sensors that detect ferrous and non-ferrous metal without touching it. Sensing distance, barrel diameter (M8, M12, M18, M30), shielded or unshielded construction, and PNP or NPN output are the specs that matter; long-range variants trade housing size for distance.

Limit switches 152 products

Mechanical position switches with plunger, roller, lever and rod actuators for end-of-travel and position confirmation. Body material, actuator style, contact configuration and IP rating are the four decisions; snap-action and slow-action contacts behave differently on slow-moving machinery.

Safety switches 111 products

Interlock switches, tongue-operated switches, rope-pull switches and conveyor belt alignment switches that stop a machine when a guard opens or a hazard is reached. Actuator type, contact configuration — positively opening NC contacts are essential — and IP rating define selection.

Pressure transmitters & Switches 97 products

Transmitters giving a 4-20 mA or 0-10 V signal proportional to pressure, and mechanical switches that change state at a setpoint. Pressure range, accuracy as a percentage of full scale, process connection and medium temperature range are the four selection points.

Sensor connectors & Cables 72 products

M8 and M12 pre-moulded cordsets, field-wireable connectors, splitters and extension leads for sensor wiring. Pin count, straight or 90-degree plug angle, cable length, and PVC or PUR jacket are the variables.

Safety light curtains & Controllers 71 products

Optoelectronic guards that create a sensing field across a machine opening and stop motion when it is broken. Protected height, resolution — finger, hand or body detection — and safety category determine the model; controllers and muting modules are listed alongside.

Float switches & Liquid level sensors 68 products

Cable-suspended float switches, vertical float sensors and continuous level probes for tanks, sumps and reservoirs. Float switches give a simple high or low signal; level probes report the whole range. Cable length, contact rating and chemical compatibility all apply.

Fibre-optic & Laser sensors 30 products

Fibre amplifiers with plastic fibre heads for detection in tight spaces, and laser sensors where a small, precisely aimed spot is needed. Both offer far finer resolution than a standard photoelectric sensor at short range.

Ultrasonic sensors 25 products

Distance and presence sensors that work on sound rather than light, so clear, shiny and dark surfaces are all detected the same way. Sensing range, blind zone, beam angle, and whether the output is switched or analogue determine the fit.

Safety lockout hasps 17 products

Lockout hasps, padlocks, valve covers and tag kits for lockout/tagout during maintenance. Hasp jaw size sets how many padlocks can be applied; non-conductive bodies are the ones to use on electrical isolation points.

Safety relays & Controllers 17 products

Safety relay modules and configurable safety controllers that evaluate emergency stops, guard switches and light curtains, then switch the machine's power contactors. Input channel count, achievable performance level, and whether reset is manual or automatic are the deciding factors.

Smoke detectors 10 products

Optical and heat detectors for panel and room protection, giving early warning of fire in electrical spaces. Supply voltage, detection principle, and whether the unit provides a volt-free relay output for the control system are the practical specs.

Occupancy sensors 9 products

PIR and microwave occupancy detectors that switch lighting and ventilation on presence. Detection pattern, mounting height, time delay and lux threshold determine coverage; wall and ceiling-mount variants are listed separately.

Flow sensors & Switches 6 products

Paddle, thermal and differential flow devices that confirm a pump is actually moving liquid. Switched outputs protect against dry running; analogue outputs feed a flow reading back to the controller. Pipe size and process fitting need to be confirmed first.

Vibration & Inclination sensors 4 products

Sensors that detect abnormal vibration or a change in tilt angle, used for machine condition monitoring and tip protection. Switching threshold is usually adjustable; output type and mounting orientation are stated per model.

Miniature relays 178 products

Plug-in miniature relays in 8-, 11- and 14-pin formats with matching sockets, retaining clips and LED or diode modules. Chosen by changeover count, contact rating and coil voltage; the socket and hold-down clip are separate items.

Plug-in timing & Monitoring devices 118 products

Timers and monitoring relays in the same plug-in socket format as miniature relays, so an existing base can be reused. Multifunction models cover several timing modes in one part number, cutting the number of spares held.

PCB mount relays 117 products

Sub-miniature and power relays for direct soldering to a printed circuit board. Contact arrangement, switching current, coil voltage and pin pitch determine the footprint — 5 mm and 7.62 mm pitches are the common ones.

Modular contactors & Relays 116 products

DIN-rail contactors for lighting, heating and general switching in distribution boards, in 17.5 mm module widths. Rated on AC-1 current rather than motor duty; quiet AC and DC coil versions are available where the board sits in an occupied space.

Solid-state relays 77 products

SSRs that switch resistive and inductive loads with no moving contacts, giving silent operation and long life on fast-cycling duty. Sized by load current with a healthy derating factor and always specified with a heatsink; zero-cross and random-fire firing modes suit different loads.

Relay interface modules 53 products

Slim 6 mm interface relays that convert a PLC output into a volt-free contact, saving rail width in dense panels. Look at input voltage, contact rating, and whether the module carries a pluggable relay or a fixed solid-state output.

Protection relays & Monitoring devices 52 products

Voltage, current, phase-sequence, phase-loss, earth-fault and thermistor relays that watch a circuit and trip before damage occurs. Adjustable setpoints and hysteresis, with modular DIN and plug-in formats listed side by side.

Level control relays 39 products

Conductive and float-based level relays that start and stop pumps on tank level, with adjustable sensitivity for different liquid conductivities. Fill and empty modes, probe count and the electrode set are listed together.

Power relays 39 products

Higher-current plug-in and panel-mount relays for switching loads beyond what a miniature relay's contacts will take. Rated in amps per contact at a stated voltage, with AgSnO₂ contact materials for inrush-heavy loads.

Modular timing devices 34 products

DIN-rail timers covering on-delay, off-delay, star-delta, cyclic and multifunction modes. Timing range, supply voltage, and whether the output is a changeover contact or a semiconductor are the practical differences.

Daylight & Time switches 33 products

Photocell daylight switches and analogue or digital time switches for lighting and load scheduling. Digital units carry weekly programmes with holiday and astronomical modes; check the switching current and whether a power reserve holds the clock through an outage.

Analogue signal converters 11 products

Signal isolators and converters that scale, isolate and translate between 4-20 mA, 0-10 V, thermocouple, RTD and pulse signals. Look at input and output type, isolation voltage, and whether the unit is loop-powered or needs an auxiliary supply.

Panel-mount analogue meters 255 products

Moving-iron and moving-coil analogue instruments for at-a-glance indication where a digital readout is unnecessary. Scale range, CT ratio, cut-out size, and whether an overload scale marking is needed are what to specify.

Current transformers 228 products

Solid-core and split-core CTs that step primary current down to a 5 A or 1 A secondary for meters and relays. Ratio, accuracy class, VA burden, and the primary bar or cable diameter the window must accept are the four things to confirm.

Power monitoring systems 81 products

Modular measurement systems that put a compact metering module on each circuit and gather the data over a single bus. Far less panel space and wiring than one meter per circuit, and the natural choice when metering a whole distribution board circuit by circuit.

Multifunction meters 59 products

Panel meters measuring voltage, current, power, power factor, frequency and energy on all three phases in one instrument. Panel cut-out size, accuracy class, communications port, and whether demand and harmonic data are recorded set them apart.

Panel-Mount digital meters 39 products

Digital ammeters, voltmeters, frequency meters and process indicators for door mounting. Standard 48, 72 and 96 mm cut-outs; input type, display digits, and available relay or analogue retransmission outputs decide the model.

Energy meters 25 products

Single- and three-phase kWh meters in modular DIN format for sub-metering tenants, departments and individual machines. Direct-connected up to their stated current, CT-operated above it; pulse and Modbus outputs let readings feed a monitoring system.

Servo drives & Motors 107 products

Matched servo drive and motor sets for positioning and synchronised motion, in the common wattage steps from 100 W upwards. Encoder resolution, rated and peak torque, holding brake option and the drive's pulse or fieldbus command interface define the pairing.

Programmable logic controllers (slim-type) 68 products

Compact DIN-rail PLCs for small machines and standalone control tasks, with fixed digital I/O and room for a few expansion cards. Chosen on total I/O count, supply voltage, whether analogue or high-speed counter inputs are needed, and available comms ports.

Programmable logic controllers (mid-range) 66 products

Modular controllers with a separate CPU and expandable I/O racks for plant-level control. Scan speed, programme memory, supported instruction set and the number of expansion modules the backplane accepts determine where a mid-range CPU stops being enough.

Programmable logic controllers (brick-type) 54 products

All-in-one block PLCs with a larger fixed I/O count than slim-type units, suited to packaging machines and process skids. Digital and analogue point counts, transistor or relay outputs and built-in Ethernet are the deciding specs.

Programmable logic controllers (high-performance) 54 products

High-end CPUs for large I/O counts, coordinated motion and fast deterministic scan times. Redundancy support, memory size and the number of simultaneous fieldbus networks separate these from mid-range controllers.

Communication cables & Modules 47 products

Fieldbus and I/O extension cables, terminal modules and protocol converters for PLC and servo systems. Cable listings give length and connector type; module listings give the protocol, port count and the controller family they attach to.

Human machine interface (touch screens) 25 products

Operator touch panels from small text displays to widescreen colour HMIs, communicating with PLCs over serial or Ethernet. Screen size and resolution, driver library, front-face IP rating and available USB/SD storage are the practical selection points.

Optical encoders 24 products

Incremental and absolute rotary encoders for position and speed feedback. Resolution in pulses or bits, shaft or hollow-bore mounting, supply voltage and output type — push-pull, line driver or SSI — determine compatibility with the receiving drive or counter.

Gearboxes for servo motors 13 products

Precision planetary gearboxes that trade servo speed for torque while keeping backlash low enough for accurate positioning. Selected on ratio, rated output torque, backlash in arcminutes, and the motor shaft and flange they clamp to.

Industrial panel PC 7 products

Fanless panel PCs for SCADA, machine visualisation and edge computing on the plant floor. Specified by screen size, processor and memory, the IP rating on the front bezel, and the panel cut-out.

Crimping die sets & Accessories 64 products

Interchangeable dies, nests and locators for hand, hydraulic and battery crimping tools. Each die is matched to a specific tool family, conductor size and crimp profile — hexagonal, indent or radial — so confirm the tool before ordering.

Hand-operated crimping tool 32 products

Ratcheting hand crimpers for ferrules, insulated terminals and small lugs, with a release that only opens once the crimp is complete. Cross-section range and whether the tool takes interchangeable dies are the selection points.

Cable preparation tools 14 products

Knives, sheath strippers, deburring tools and multifunction preparation tools for getting cable ready to terminate. Sized by the cable diameter range the tool is designed to work on.

Hydraulic & Battery-operated cable preparation tools 14 products

Hydraulic and battery crimping and cutting tools for large conductors where hand tools cannot produce a compliant crimp. Rated by crimping force in tonnes and maximum cable cross-section; dies are ordered separately.

Portable network analyser 14 products

Portable power quality analysers and loggers for recording voltage, current, harmonics and events on a live installation. Channel count, recording period, harmonic order captured, and the software supplied for report generation are the practical differences.

Hand-operated cable strippers 9 products

Precision strippers for control wire, coaxial and larger insulated cable, including self-adjusting and rotary types. Conductor size range and whether blade depth is adjustable determine what a stripper handles without nicking the copper.

Thermal camera & Electrical installation tester 7 products

Thermal imagers for finding hot joints and overloaded circuits without contact, and multifunction installation testers for insulation resistance, loop impedance and RCD testing. Both are compliance tools, so check resolution and test ranges against what you have to certify.

Digital & Clamp multimeters 6 products

Digital multimeters and clamp meters for installation and fault-finding work. Measurement category rating, true-RMS capability, AC and DC current clamping, and the range of secondary functions such as temperature and capacitance separate the models.

DIN rail & Cable trunking cutters 5 products

Bench and hand cutters that give a clean square cut on DIN rail and PVC trunking without deforming the profile. Faster and more accurate than a hacksaw, and they leave no swarf inside a wired panel.
