Encoders of this kind are often used in CNC machines

Optical Endstop Gas Sensor Parallax reported using the MelexisThe Optical encoder Endstop, which is very accurate and easy to use . When the light is blocked, Opto Endstop will immediately output the digital control, and the LED will be on. Opto Endstop adopted standard electronic brick interface, therefore, it is easy and convenient to plug and play. Operating voltage: DC 5V Opto stop on reprap wiki
