Encoder Photoelectric Speed Measuring Module

The module operates within a flexible voltage range of 3.3 to 5.5 volts, ensuring compatibility with various power sources. It incorporates an imported groove coupler sensor with a precise groove width of 5mm, enabling accurate detection of objects passing through. When the sensor slots are obstructed, it outputs a high signal and the indicator light remains off; conversely, when there's no obstruction, it outputs a low signal and the light activates. Its output is in the form of digital switching, represented by 0 and 1 states. Utilizing the LM393 comparator output ensures clean signals with excellent waveform characteristics, capable of driving loads exceeding 15mA. Additionally, the module features a fixed bolt-hole for effortle
