KEMET Electronics Sensors include current, thermal, and proximity detection sensors. Current sensors are used to measure the amount of current flowing in a circuit and are available as low- or high-alternating current transformers, zero-phase transformers, and direct/pulse current sensors.
Thermal sensors or temperature-sensing switches can be used to make or break an electrical connection when the defined threshold temperature is reached. These sensors or temperature-sensing switches are composed of a magnet and Thermorite, a temperature-sensing soft ferromagnetic substance. Their design and material allows for quick response times, an extended operational lifetime, and provides stability against moisture and hazardous gas.
Proximity sensors detect human presence and have a pyroelectric principle of operation that generates a voltage when exposed to infrared radiation, as a result of a change in temperature. These sensors can also detect infrared rays without using lenses, resulting in a low profile and can be concealed behind certain materials, allowing to play on the detection distance.
