Temperature sensors and thermistors (PTC-series)

Data sheet

You will receive a complete overview of all variations in connection with all the technical data in the following data sheet:


Temperature sensors of the YAM / EF1 type series are the PTC thermistor or the motor PTC, which are characterized by a sudden increase in resistance at a def. response temperature.

The special field of ​​these sensors lies in the area of ​​the heavy load motors (3-phase, 1-phase), in which no direct disconnection due to the high current is possible. The motor PTC is used as a sensor and, like a temperature switch, emits a very high resistance level from a certain response temperature level. Through this, for example, it is possible to switch a fuse by means of an evaluation unit.
