HN3806 5-24V Rotary optical encoder 400 degrees 2-phase

Encoders convert changes in position and direction into electrical signals. In fact, an encoder is a sensor that is connected to the axis of a wheel, rotor, or motor and can measure the amount of rotation. By measuring the amount of rotation, displacement, speed, acceleration, or angle of rotation can be determined.
A shaft encoder is an optical sensor that converts a mechanical movement (linear and rotational) into an electrical signal so that different characteristics can be used from that signal, or more simply, encoders are devices that convert rotational or linear movement into a digital signal of 0 or 1.
Of course, it goes without saying that some encoders also have analog outputs (0 to 10 volts or 4 to 20 mA).

Connections:
Green: Phase A, White: Phase B, Red: VCC power supply, Black: Zero voltage

Note:
The two-phase AB output should not be directly connected to VCC, otherwise it will burn the output triode.
