M12 micro DIN enabled temperature sensors
12 August 2011
Omega’s new M12 Thermocouple and Pt100 sensors are easy to install and maintain. Termination is achieved through a polarised M12 connector with a hand-tightened knurled nut - an arrangement that completely eliminates wiring errors. Moreover, as no tools are required, a sensor changeout can be achieved very quickly.

Previously the only options available for cold end termination were traditional in-line plastic connectors or conventional terminal head arrangements where a more permanent, robust installation was required. Those were often supplied with vague IP ratings and a variety of electrical connections requiring additional thread adaptors and termination glands to complete the system. Having a vibration resistant construction, low probe mass and an ingress protection rating of IP67, they are suitable for a broad application range.
They are available off-the-shelf with either a stainless steel or Inconel sheath in diameters of 3mm and 6mm and with standard lengths of 200, 500, 750, 1000 and 1500mm. The range is further enhanced by a variety of process fittings including BSP, NPT and metric mounting threads, as well as Tri-clamp flanges for hygienic and vacuum applications.
