General Description

The NJL5312R is a sensor that reduces the affect of scattering from reflection light at cover material by ingenuity of the package structure. This sensor is a highly integrated Photo-sensor, which combined two high brightness Green LEDs and a high sensitivity Si photo diode with visible light band-pass filter. NJL5312R is a sensor for pulse rate (heart rate) measurement which shows one of fitness application that targeted the fitness tracker like Smart watch/Band/Bracelet.


  • Pulse rate (Heart rate) of Wearable Devices(In-Ear phone, Smart watch, Fitness Tracker etc.)
  • Mobile Devices
