The sensor consists of a plastic head and a metal surface placed in a POLYAMID plastic protective cover 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 the digital output signal depending on the type of sensor are connected via a cable gland and a connector. 

SD 144, SD 144K  CANopen / CiA DS 301 communication protocol, CAN bus communication

The temperature range of the sensors is defined in the table of technical parameters for each variant of sensor. The sensors comply with the protection class IP 65 standard EN 60529 modified.

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