TRS-W Thermal Reed Sensor

Molded NC Thermal Reed Sensor Drawing
All dimensions in mm


Switching range available from 25°C to 130°C with +/- 3°C tolerance Does not require external power for operation Normally Closed contact Sputtered Ruthenium contact RoHS Compliant and Lead-free Not Sensitive to ESD For low level 10W loads Temperature differential of 10°C max


These thermal reed sensors can accurately monitor temperature within 2-3C and are suitable for a wide range of applications. The load switching capability is that of the reed switch used, which is 10W. As these are a direct replacement to bimetallic strips, these themal reed sensors are only available in a normally closed, form B type contact, which opens when the configured temperature is reached.
