The KOBOLD TRS thermal reed switches are widely used for temperature monitoring and control. The rugged, straightforward design is noted for having both long life and reliability. Thermal reed switches have high repeatability as they are insensitive to the operating environment and are not affected by load current. Constructed with a rugged brass or stainless-steel housing and 1/4" to 1" internal threads on both sides for inline installation, they are supplied with a 5' silicone jacketed cable for convenience. The temperature contacts have a fixed, factory-set switchpoint in intervals of 9 °F over the ranges of 50 °F to 122 °F and in intervals of 18 °F over the ranges of 140 °F to 248 °F.
