It's a Speed Measuring Sensor Groove Coupler Module. This is a high quality sensor module which has the output indicator led, if output level is high, it will off otherwise it will on. The LM393 wide voltage comparator has been installed in this module. Through this sensor module provides Good signal and waveform, with a strong driving ability for more than 15mA.
