Thermal switch latcher

These thermal switches are used for monitoring/controlling temperature without an electricity supply.

With a latcher, the circuit is broken upon reaching a defined temperature threshold or a temperature that is too low within a predefined temperature range.

Temperature latchers prevent automatic resetting using a high-value resistance in parallel to the contact system. The circuit is closed only after disconnecting the voltage and a short cooling-off phase.

Special models for specific applications are available on request.

Housing material and temperature ranges:

  • Plastic (SO),
    Temperature range -60°C to 200°C 
  • Ceramic (HCSO/VCSO/CSO)
    Temperature range -60°C to 390°C

Degree of protection for the housing: IP 40
