About this item
* Adopting a slot type photoelectric sensor, it consists of an infrared light-emitting diode and an NPN photoelectric transistor, with a slot width of 5.9mm.
* As long as a non-transparent object passes through the slot, it can trigger to output a low TTL level.
* Using Schmidt trigger to jitter pulses is very stable and can be used for small car speed measurement, distance measurement, and other applications!
* Install holes with M3 screws at both ends.
* Working voltage: 3.3V-5V, output form: digital switch output (0 and 1)
