Im393 Motor Speed Measuring Sensor Module

Im393 motor speed measuring sensor module is Used in motor speed detection, with good signal and waveform with strong  driving ability for more than 15 MA pulse count, the position limit Using imported groove optical coupling sensor, width 5mm.It has the output state light, if output high level, the lights are off. if output low level, it on. The DO output interface can be directly connected to a micro-controller IO port if there is a block detection sensor, such as the speed of the motor encoder can detect. It can be connected to the relay limit switch, and other functions it can also with the active buzzer module compose alarm.
