The MaxWell MS-3DA4880 is a heavy-duty 80A Three-Phase Solid State Relay (DC to AC), designed for reliable control of 24-680VAC loads. This ready-to-use kit comes fully pre-assembled with a customized heavy-duty aluminum heatsink and a high-velocity cooling fan, ensuring optimal thermal management and continuous operation under heavy loads. Featuring advanced Back-to-Back SCR technology, Zero-Crossing switching, and a built-in RC snubber circuit, it delivers superior surge protection, minimal EMI, and long-term stability. Ideal for industrial heaters, HVAC systems, and plastic machinery, it is CE certified, fully resin-sealed for 3500V high isolation, and engineered for plug-and-play safety and performance.

The PT100-9 is a tri-clamp liquid-tight Platinum Resistance Thermometer (PT100 RTD) engineered for reliable and accurate temperature measurement in sanitary and process environments where a secure, leak-proof connection is essential. The sensor features a stainless steel flanged tri-clamp fitting that forms a robust liquid-tight seal, making it ideally suited for food processing, dairy, brewing, pharmaceutical, and chemical applications where hygiene and contamination prevention are paramount. The probe is constructed from stainless steel and is available in three diameters (4 mm, 5 mm, and 6 mm) with probe lengths of 30 mm, 40 mm, or 50 mm, all of which can be customised to meet specific installation requirements. Lead wire material is fully selectable — stainless steel braid, silicone, fiberglass, or Teflon — allowing the sensor to be matched to the thermal and chemical conditions of the surrounding environment. Lead wire length is available in 2 m, 3 m, or 5 m. The “-TC” suffix in the ordering code designates the tri-clamp liquid-tight connection, clearly distinguishing this series from standard probe-type RTDs.

The PIDMaxWell KSK600D25 is a high-performance single-phase solid state relay (SSR) designed for reliable switching of AC loads in industrial automation and power control systems. With a wide 4-32VDC control voltage and 24-660VAC load voltage range, it delivers stable performance across diverse applications. The 25A rated current and 800Apk surge current capability ensure safe handling of inductive and resistive loads. Featuring 4000Vrms dielectric strength, CE & cULus certification, and a compact DIN rail mountable design, the KSK600D25 is an ideal solution for industrial heating, CNC machinery, motor control, and commercial lighting systems.

MF43HYC-652A is a 4 channel touch screen temperature controller, works with 4 input and 4 outputs, support thermocouple inputs and output is optional between, SSR Drive, 4-20mA or Realy, PC and cell phone compatible, Modbus TCP/IP optional, 4.3'' touch screen, datalogging feature, with USB, WIFI, and Ethernet port. Operation interface in English, Chinese and Spanish.

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.
