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 Typical applications Angular encoder • Electric vehicles • Type Ordering Code FP 312 L 100 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.
