Screw clamp type temperature sensor, for sensing the temperature of Transistors, Thyristors, stereo main amplifiers, and
other devices having risk of overheat.
Limit temperature sensor with epoxy resin coating.
Tinned pin leads wire.
Metal lug tag screw clamp type easy mounting.
Metal tag lug permits good thermal coupling and thus short response time.
Making use of the characteristics that the resistance of ceramic PTC thermistors increases sharply above curie temperature, when ambient temperature increases abnormally, protective circuit installed PTC thermistor will turn on or cut off loop through resistance changing, achieving thermal protection purpose.
PTC thermistors protect such equipment and components as motors, transformers, power transistors and thyristors against over-temperature.
A PTC thermistor is less expensive than a thermostat, and its switch temperature can be more accurately specified. It is also smaller and easier to design-in to electronic circuitry. Therefore PTC thermistors can be ideal devices for temperature detection, monitoring, indicating, limiting and over (excessive) temperature protection.
