The Maxwell MS-1DD60 series is a high-performance, single-phase DC to DC solid state relay designed for reliable switching in demanding industrial applications. Featuring a wide control input range of 5–32VDC and a load voltage rating of 60VDC, this compact panel-mount relay utilizes advanced MOSFET triggering technology to ensure fast response times and noise-free operation. With load current options ranging from 10A to 120A, the MS-1DD60 series is engineered with a uniform physical size across all models, simplifying installation and system design. Its robust black housing and integrated LED process indicator make it an ideal choice for precise control in small heating applications, valve control, and other inductive or resistive loads. All models comply with CE and RoHS standards, ensuring suitability for global industrial deployment.

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 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 TC-K14B is a fast-response K-type thermocouple engineered for applications where rapid, accurate temperature measurement is essential. Unlike conventional sheathed thermocouples, the TC-K14B features an exposed welded-bead junction with minimal thermal mass, enabling it to detect temperature changes within fractions of a second. This makes it the preferred choice for dynamic temperature monitoring tasks in research, testing, and industrial quality control environments. The sensor is constructed from a fine-gauge Chromel-Alumel (K-type) thermocouple wire pair, twisted together and insulated with a flexible fiberglass braid. The green-and-white color coding of the lead wire follows the international K-type thermocouple standard, providing clear polarity identification. The fiberglass insulation offers excellent thermal resistance and flexibility, allowing the sensor to be routed through confined spaces and around complex geometries without risk of insulation damage. At the instrument end, the TC-K14B is fitted with a standard miniature K-type quick-disconnect connector (green housing, labeled 'K NiCr+ / NiAl−'), which is compatible with a wide range of handheld thermometers, data loggers, and temperature indicators that accept the IEC 60584 / ANSI miniature thermocouple connector standard. The plug-and-play design eliminates the need for field wiring, enabling rapid deployment and sensor replacement without tools or specialist knowledge. The lead wire length is fully customizable, making the TC-K14B adaptable to installations where the measurement point is located at a significant distance from the instrument. As part of the PIDMaxWell range of temperature measurement solutions, the TC-K14B is designed to integrate seamlessly with PIDMaxWell PID temperature controllers, temperature transmitters, and compatible third-party instrumentation.
