NJL5501R

Reflective optical sensor well suitable for Pulse Oximeter and Heart rate monitor

Most of the Pulse Oximeters employ a transmission type optical sensor on their probes. It is necessary to clamp a projecting part of the human body, such as a finger and an earlobe. And clamping causes problems to be solved such as oppressive feeling and blood flow blocking.
We have developed the reflective optical sensor mounting IR / RED LEDs and one photo transistor in an small thin package which can provide the reflective measurement without clamping, and provide a solution of the problems.

Features:

  1. Providing reflective optical measurement to Pulse Oximeter
    The NJL5501R provides the reflective optical measurement, and it can chage the probe from clamping type to attaching type. 
  2. Employing the emission wavelength range required by Pulse Oximeter
    The NJL5501R employs the emission wavelength range required by Pulse Oximeter, therefore it can provide a high precision measurement.
  3. The industry’s first 1-package reflective optical sensor for Pulse Oximeter
    The NJL5501R is the industry’s first 1-package reflective optical sensor mounting IR / RED LEDs and one photo transistor in a small and thin package.

Characteristics:

  • Peak emission wave length
    660nm ± 3nm (RED)
    940nm ± 10nm (IR)
  • Output current
    1.0mA to 4.3mA (RED)
    145µA to 580µA (IR)
  • Outline     COB Package (1.9mm x 2.6mm x 0.8mm)
  • Pb-free, Halogen-free
  • Compliant with RoHS directive

Applications:

Pulse Oximeter / Heart rate monitor
