Detect surface temperatures from 0F-300F (-17.8C to 148C). Plastic body (thermoplastic polyetherimide high heat polymer), stainless steel mounting flange with .188″ dia. slots.
CPI’s SnapStat line of bimetallic thermal switches have a bimetal snap disc that actuates a miniature microswitch. This double snap action makes these switches virtually immune to shock and vibration. Epoxy sealing or glass to metal hermetic sealing makes them ideal for demanding industrial or military applications.
