## Overview

The WMYCONGCONG KY-040 is an 8-pack rotary encoder module set designed for Arduino microcontrollers, featuring continuous 360-degree rotation with no limit on counts, a built-in push-button reset, and durable mounting hardware. Operating at 5V, these compact modules deliver precise incremental pulse signals, ideal for professional prototyping and embedded control applications.

## Description

Specification: KY-040 Module: Working voltage: 5V Pulse circle: 20 Material: electronic components + PCB Size: 26 x 19 x 29mm/1.02 x 0.75 x 1.14inch Diameter of the thread: 7mm/0.27inch Height of the thread: 7mm/0.27inch Knob Cap: Diameter: 15mm/0.59inch Height: 16.5mm/0.65inch Connection: "GND”: ground terminal "+”: 5V power supply "SW”: 'Select' switch (activated when shaft pressed on top) "DT”: Encoder Pin B "CLK”: Encoder Pin ADesigned with detent and push button switch feature, comes with nuts and washers, suitable for Arduino micro controller use. By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer counter, which species rotation counts are not limited. How it works: incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensors. Package Content: 8 pack KY-040 rotary encoder module(knob, nut, washer included)

Review: No knobs as advertised - Great little encoders but didnt come with knobs as described
Review: Hmm. This product could use a deep socket nut so it could be built into 3/8" front panel hole. Am improvising. It will work with an embedded microcontroller and act as a coarse sweep switch on an oscilloscope where the micro generates the sweep waveforms. It is elegant !

## Features

- The rotation counts are not limited, designed with continuous 360 degree rotation sensors.
- Working voltage: 5V
- Material: Electronic components + PCB
- Reset to its initial state with the buttons on the rotary encoder, starts counting from 0.
- Designed with detent and push button switch feature, comes with nuts and washers, suitable for Arduino micro controller use.
