NJL5820R

Rotary Detection Sensor with Optical Reflection Type

Features
  • Miniature, thin package (2.6mm x 2.5mm x 0.8mm)
  • Digital two outputs type (A/ B phases)
  • Resolution (50.8LPI * Lines Per Inch (2LPmm * Lines Per mm))
  • Recommendation strip width (0.25mm)
  • Pb free soldering re-flowing permitted (255°C, 2times)

General 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.
Applications
  • Rotation detection of focus ring
  • Rotation detection of the operation dial
  • Rotation detection of the encoder plate
