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 PT100-19 is a probe-type PT100 Platinum Resistance Thermometer equipped with an M12 4-pin connector, combining the measurement accuracy of a Class A PT100 element with the convenience and reliability of the industry-standard M12 circular connector interface. The M12 4-pin connector enables rapid, tool-free mating and de-mating in the field, eliminates the need for field wiring, and provides a secure, vibration-resistant connection that is well suited to machine-building, automation, and process control applications. The sensor is constructed from SS316 stainless steel throughout, offering excellent corrosion resistance in wet, chemical, and marine environments. The probe diameter and length are fully customisable to meet specific installation requirements, and a range of process fittings — including ½ NPT, ¼ NPT, ¼ BSP, ½ BSP, M8, M10, and M12 thread forms — allows the sensor to be installed directly into standard process pipework and vessels. The sensor complies with EN 60751 Class A accuracy, covering a temperature range of −50 °C to +250 °C, and is available with cable lengths up to 7 m or longer on request.  

DIN rail clamps for heatsinks and solid state relays, some of heatsinks can't be mounted to standard din rail, but the heatsink can be attached to this din rail clamps, and then mounted to a DIN rail.
