Speed Measuring Sensor

1. Using imported groove optical coupling sensor, width 5mm.
2. It has the output state light, if output high level, the lights are off. if output low level, it on.
3. If it covered, it will output high level; otherwise, its output low level.
4. Good signal and waveform, with a strong driving ability for more than 15mA.
5. Equipped with a fixed bolt hole, easy install.
6. Use the LM393 wide voltage comparer.
