NJL9101R Preliminary Opt-Pass Sensor GENERAL DESCRIPTION The NJL9101R is the high-precision optical position sensor, which is combine with a super luminosity RED LED and Si light-sensitive element into small package. Three sine waves with high precision phase difference will output by using the dedicated striped mirror (NJL9600 series). 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 (NJL9101R,NJL9600 series) sensor has been designed strongly against the distance variation between the sensor and the special striped mirror. Also the Opt-pass has been designed against the tilt variation. FEATURES Output voltage : 90mVp-p typ.
