TRS-W Thermal Reed Sensor
Features
Temperature range of 25°C to 130°C. Less than 3°C tolerance. Normally Closed Contact. For Low level 10W loads.
Description
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.
