Shaft Rotary Encoder Sensor

Description

Shaft Rotary Encoder Sensor The HW-040 is a highly versatile, compact shaft rotary encoder module mounted on a convenient breakout board, making it perfect for DIY electronics, prototyping, and microcontroller projects. Unlike standard potentiometers, this rotary encoder provides continuous 360-degree rotation tracking via quadrature outputs, allowing you to accurately measure relative changes in position, speed, and direction. It features three integrated 10kΩ pull-up resistors on the back of the PCB and an integrated push-button shaft switch for enhanced control functionality.
