The TC-K4/TC-J4 series is a high-performance, versatile probe-type thermocouple temperature sensor designed for a wide range of industrial, scientific, and process-control applications. The sensor consists of a stainless-steel protective sheath enclosing a precision thermocouple element, terminated with a braided-shield extension lead wire and fork-type (spade) terminal connectors. Four thermocouple calibration types — K, J, T, and E — are available to cover measurement ranges from cryogenic temperatures down to -200 °C up to +1260 °C, accommodating virtually every industrial temperature-measurement requirement.

The probe sheath is manufactured from 304 stainless steel, offering excellent corrosion resistance and mechanical durability. The extension lead wire is protected by a metallic braided shield (aluminium foil + tinned-copper braid) that effectively suppresses electromagnetic interference and ensures signal integrity over long cable runs. Both probe diameter and insertion length are fully customisable, and the lead wire length can be specified to any required dimension. An optional waterproof (IP67) sealed construction is available for use in wet or immersion environments. All products comply with IEC 60584 international standards.

The PIDMaxWell Quick Connectors series provides a complete range of thermocouple quick-connect plugs and sockets for use with K, J, T, E, and N type thermocouples and extension wires. Available in both standard and miniature sizes, and in nylon (up to 220 °C) or ceramic (up to 650 °C) body materials, the connectors are colour-coded in accordance with universal thermocouple standards — yellow for K, black for J, violet for E, blue for T, and orange for N — making polarity identification and type verification immediate and error-free in the field.

Each connector is supplied as a matched male (plug) and female (socket) pair. The polarised pin geometry prevents incorrect insertion, and the screw-terminal wire clamps inside each connector body accept a wide range of thermocouple and extension wire gauges without soldering. The compact miniature format is ideal for space-constrained installations and portable instrumentation, while the standard format provides a more robust grip for fixed industrial installations. All connectors are fully customisable and available in bulk quantities to order.

The KFY-002 is a compact, waterproof thermocouple and RTD connection head (terminal box) designed for reliable field installation in demanding industrial environments. Featuring an aesthetically pleasing die-cast body with a brilliant, durable paint finish available in grey and yellow, the KFY-002 combines robust protection with ease of use.

The spacious internal cavity provides ample room for comfortable, tool-free wiring, significantly reducing installation time. The standardised internal height of H = 33 ± 0.1 mm ensures full compatibility with internationally sourced terminal blocks and signal converters, enabling seamless integration into global instrumentation systems.

The KFY-002 is designed to accommodate virtually all common sensor configurations: standard thermocouples, PT100/PT1000 thermal resistors, armoured (mineral-insulated) thermocouples and RTDs, as well as sensors fitted with integrated temperature transmitters. A stainless steel safety chain secures the lid against accidental loss during maintenance.
