Features

• 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.
• Use the LM393 wide voltage comparer
