5pcs Rotary Encoder Module for Arduino with Unlimited Rotation Count Potentiometer Replacement Used to Measure Motor Rotation and as Wheel Controller Knob from Optimus Electric

Description

The rotary encoder is the modern digital equivalent of the potentiometer. It is used over a wide range of applications because it is robust and because its rotation count is not limited.This module features a rotational displacement encoder which outputs a series of pulses whenever the switch is rotated. It features two phase outputs (A and B), that can also be used to sense the direction of rotation and a special output signal Z which indicates the absolute zero position of the rotary switch.This rotary encoder can be reset to its initial state, from 0 to start counting.It can be used as a fancy potentiometer replacement for digital amplifiers and other similar applications, allowing you to use an unlimited number of turns, in contrast to the classical potentiometers.Specifications• Operating Voltage: 5 V • Circle Pulse Count: 20 • Size: 32 mm x 28 mm x 19 mm
