Product Features

• Use imported slot type optocoupler sensor with a slot width of 10 mm.
• There is an output status indicator where the output high level light is turned off and the output low level light is on. There is disability, output high level; no obstacle, low output.
• The comparator output has a clean signal, good waveform and strong drive capability that exceeds 15mA. The working voltage is 3.3V-5V. Output format: digital switch output (0 and 1). There are fixed screw holes for easy installation.
• If there is no obstruction in the module slot, the receiving tube is conductive, and the module DO outputs a low level.
• DO can be connected to relay to form limit switches and other functions, and can also be connected to active buzzer modules to form alarms.
