Maximum performance in a miniature design: The reliable and powerful temperature switches from Microtherm are perfect for installations in tight spaces. They ensure optimum overheating protection even under extreme conditions and in the smallest of spaces.
Applications:
- Home: For e.g. roller shutter motor, aquarium, toaster, kettle, extractor fan, washing machine, dishwasher, air conditioning units, coffee machine, fans and ventilators.
- Industry: For e.g. pump and fan motors, electric motors and heaters, transformers, cooling units; power tools
- Automotive as overheating protection for motors: Windscreen wipers, heated side mirrors, seat heaters, motor windings
- Charging park: Temperature management in cooper or aluminium windings and protection of electric motors by initiating protective functions, temperature monitoring in battery management to prevent batteries from overheating, temperature monitoring of high-current connectors
- Hospital: Incubators, hospital bed motors, ventilation systems, ventilators

Microtherm sensors are used for temperature measurement. The value measured by the sensor is used for overtemperature protection, to trigger functions or to display the measured temperature. Our temperature sensors not only safeguard and protect electric motors and/or electric heaters by switching them off, but also provide signals for temperature indication, power reduction or other functions. With the help of our diverse manufacturing processes, we embed sensor elements in customised assemblies. This allows us to add value to a pure sensor element and build cost-effective measurement systems.
Applications:
- Home: Power tool, vacuum cleaner and many more
- Industry: Pump and fan motors, electric motors and heaters, transformers, cooling units; power tools and many more
- Automotive as overheating protection for motors: Windscreen wipers, heated side mirrors, seat heaters, motor windings
- Charging park: Temperature management in cooper or aluminium windings and protection of electric motors by initiating protective functions, temperature monitoring in battery management to prevent batteries from overheating, temperature monitoring of high-current connectors
