Rotary Detection Sensor with Optical Reflection Type

Download Datasheet

  • Description

    NJL5820R is the compact surface mount type photo reflector, which is built in a high Brightness Infrared LED and PDIC. It can obtain two-phase(A,B) digital signals with the recommended striped reflector. It is the optimum sensor for various kinds of rotation detection, which can contribute to low power consumption of the set and simplification of the design.
