[Mass Production Start] Reflective Type Rotation and Position Detection Sensor 'NJL5820R'
It is not affected by the magnetic field generated by the motor! Detection of rotation direction and position is possible.
New Japan Radio Co., Ltd. has started mass production of the reflective type rotation and position detection sensor 'NJL5820R', which is suitable for detecting rotation direction and position with a digital 2-phase output type. By combining a newly designed photodetector IC with a high-output infrared LED, we have achieved low power consumption. To contribute to the simplification and miniaturization of device integration, we have developed a unique method to process the reflected light from the reflector, enabling the installation of sensors with excellent robustness. 【Features】 ■ Digital 2-phase output type suitable for detecting rotation direction and position ■ Enables detection of rotation (movement) direction and position through digital 2-phase output ■ Low power consumption design, including drive current for the light-emitting element (LED) ■ Excellent robustness, strong characteristics against distance variations of stripe mirrors ■ No influence from magnetic fields *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 - By combining with the recommended reflector (stripe mirror), a 2-phase signal with a 90-degree phase shift can be obtained, allowing for easy detection of rotation (movement) direction and position. - By detecting the rising/falling edges of the 2-phase signal, a resolution of 1/4 of the reflector pattern cycle can be achieved, enabling measurements with higher precision than the physical accuracy of the stripe mirror. - By combining a high-sensitivity, low-current consumption photodetector IC with a high-output infrared LED, low current consumption suitable for battery-operated devices is realized. - Sensors can be installed without worrying about the mounting position, and magnetic field analysis during design is unnecessary. *For more details, please refer to the PDF document or feel free to contact us.
