KY040 rotary encoder แกนยาว 20mm 360 degree development board rotary encoder module

nature:

Designed with detent and push button switch feature, comes with nuts and washers, suitable for Arduino micro controller use. By turning the rotary encoder can count in positive and reverse during rotation to output pulse frequency, unlike from potentiometer Rotary counter, unlimited count rotation type.

Specifications:

Voltage: 5V
Pulse circle: 20
Material: electronic components + PCB
Size: 26x19x26mm

How It Works:

The incremental encoder is a rotary displacement pulse signal converted into a series of digital rotary sensors.

Package Included:

1x KY-040 Rotary Encoder Module
