Probe with plastic connection head - CAN protocol

  • Temperature sensors with stainless steel tube.
  • Plastic head with digital output CAN / CANOpen.
  • Temperature measurement of gaseous substances and liquids. 
  • Easy to mount thanks to the unique "S-head" design.

Product features Probe with plastic connection head - CAN protocol


This sensor includes plastic head and stainless steel tube in which a temperature sensor is placed. In the head is a terminal block or a converter with a terminal block, to which the power cable intended to supply the sensor and to the digital output signal are connected via a cable gland and a connector. 

SD124, SD124K  protocol CANopen / CiA DS 301 communication, bus communication CAN

The temperature range of the sensors is defined in the table of technical parameters for each variant. The sensors are conform to protection class IP 65 Complies with modified EN 60529. 

The sensors are designed to operate in a chemically non-aggressive environment, the method of use should be selected according to the temperature and chemical resistance of the sensor head.
