The Maxwell SCR20CA Series is a highly integrated, single-phase AC power controller designed for advanced feedback control and precise voltage regulation. Built around a high-power thyristor (SCR) chip, this compact unit incorporates a digital phase-shift control circuit alongside highly accurate output voltage and current measurement systems. A standout feature of the SCR20CA is its multi-functionality: users can seamlessly switch between constant voltage, constant current, and constant power control modes directly via the digital panel or communication interface. Equipped with true RMS sampling and a fully isolated measurement system, it ensures safe and reliable operation. With built-in RS-485 Modbus RTU communication, pluggable control terminals, and comprehensive protection mechanisms, the SCR20CA is an ideal solution for modern, automated industrial heating and power control applications.

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 NTC10K Series is a compact, high-precision Negative Temperature Coefficient (NTC) thermistor temperature sensor housed in a rugged stainless steel M8 screw-body probe. Designed for direct installation into threaded ports on pipework, tanks, heat exchangers, and machinery, this sensor delivers accurate, low-cost temperature measurement across a wide operating range without the need for signal conditioning or cold-junction compensation.At the heart of the sensor is a precision NTC thermistor element with a nominal resistance of 10 kΩ at 25 °C and a B-value (B25/100) of 3950 K ± 1%. The thermistor element is encapsulated within a 4 mm diameter stainless steel probe, sealed with high-temperature epoxy resin to ensure moisture ingress protection. The M8 threaded body incorporates a high-temperature silicone gasket to provide a leak-proof seal when installed into a threaded port. A 150 mm flat silicone lead wire terminates in a standard 2-pin SMP (Micro-Fit style) connector for fast, tool-free connection to the host system.The NTC10K series is fully compatible with Maxwell's range of temperature controllers, as well as third-party controllers, HVAC control boards, and microcontroller-based systems that accept a passive NTC thermistor input. The sensor's small probe diameter, short lead wire, and plug-and-play connector make it an ideal drop-in component for OEM equipment manufacturers and system integrators.
