Ričards Sleņģis
Turck CMMT measures magnetic field changes on three axes, calculates their vector sum and measures temperature. The sensor detects movement, rotation and changes in magnetic components without contact, including where optical sensors have no line of sight.

Humidity and temperature measurement in M12 housing

Humidity and temperature in one sensor
One sensor measures humidity and temperature and calculates the dew point, allowing for timely detection of condensation risk and overheating.

IO-Link and SIO mode
Through IO-Link, the sensor transmits values, histograms, and operating hours. In SIO mode, two switching outputs alert based on set threshold values or windows.

Measurement range -40...+100 °C
Suitable for many industrial environments and equipment.

Robust housing
Metal housing with IP67 protection class. /3GD variant for zones 2/22.
