“T” SERIES – 1/2″ Epoxy Sealed
Senasys Epoxy Sealed Bimetal Thermostats are single pole, single throw and are perfect for applications where a moisture and dust proof enclosure is required for a safe, sensitive, and reliable operation. The polypropylene boot enclosure, filled with epoxy resin, covers the thermostat and the the bimetal disc control element is in close proximity to the sensor cap to provide rapid response to temperature changes. Additionally, multiple mounting options, terminals, and temperatures are available.
431 Epoxy Sealed Bimetal Thermostats are highly versatile carrying up to 15 Amps at 120VAC and are available SPST. The bimetal thermodisc within is set to a precise temperature range between -20°-220°F (-25°-105°C). Your temperature range will determine when the thermal switch will close, or engage the electrical circuit, and when it will automatically reset, or open. Additionally, a specific temperature range may be designed according to your application needs.
