FP312L100

Contactless Potentiometer FP 312 L 100 Dimensions in mm Features Devoid of friction and abrasion at contact point No electrical contact noise Insensitive to contamination, moisture ingression, corrosion and vibration Low operating torque Long lifetime Type FP 312 L 100 Typical applications Angular encoder Electric vehicles Ordering Code Q65312-L100-U This potentiometer comprises differential MR, driven by a magnet with no amplifier. At the output, the resistance change can be used as a signal. On applying the operating voltage a sinusoidal voltage results at the output, which is not temperaturecompensated. With the aid of external circuitry this signal can be amplified, temperaturecompensated and adapted for various applications.
