DESCRIPTION Rotary encoder module rotates all the way round continuously clockwise and anticlockwise. Each movement clockwise or anticlockwise causes the two switches to open and close. There is no way to know what the current position is - instead you would use a microcontroller to count how many clicks left or right it has been turned. During rotation, the output is a pulse frequency. It can be used to measure rotational speed, angle and acceleration of an object. Note: AB 2-phase output must not be directly connected with VCC otherwise it will burn the output triode. TECHNICAL DETAILS Input Voltage: 5V Output: AB 2-phase output rectangular quadrature pulse, NPN open collector output type Pulse: 20 Pulse per Revolution SHIPPING LIST 1x Rotary Encoder 20pulse/rev 1x Washer & Nut 1x Knob Cap
