- Using imported groove optical coupling sensor, width 5mm.
- It have the output state light, if output high level, the lights are off. if output low level ,it on.
- If it covered,it will output high level;otherwise it output low level.
- Good signal and waveform, with strong driving ability for more than 15mA.
- The working voltage of 3.3V to 5V.
- Output: digital switch output (0 and 1).
- Equipped with a fixed bolt hole, easily install.
- Small board PCB size: 3.2 cm x 1.4 cm.
- Use the LM393 wide voltage comparer.
