  • Description

    The NJL9101R is the high-precision optical position sensor, which is combining with a super luminosity RED LED and Si light-sensitive element into small package. Three sin waves with high precision phase difference will output by using the dedicated striped mirror. By arithmetic processing of the sensor output signal, the position detection with high precision and high resolution can be performed. The characteristics by optical scheme are not affected from the magnetic field of magnet that built into the motor etc The Opt-Pass sensor has been designed strongly against the distance variation between the sensor and the striped mirror. Also the Opt-pass has been designed strongly against the tilt variation.
