KY-040 Rotary Encoder Sensor Module
DescriptionWhat is the KY-040 sensor?
The KY-040 Module is a rotary encoder, it is an incremental encoder with two phased outputs that will indicate the direction in which the axis is turning.
It has 12 positions (every 30º) and infinity, that is, we can turn to both sides without limit.
When we go through each step you will notice a small highlight that indicates that the new position has been reached.
What is the KY-040 for?
This Rotary Encoder is widely used in the control of stepper motors, servo motors, control of digital potentiometers, controls of industrial machines such as spindles of CNC lathes and milling machines, robotic arms, controls of electronic instruments (dials) and it is even possible.
What is an encoder sensor?
The Encoder is an electromechanical device that allows encoding the mechanical movement in different types of electrical impulses: binary digital, analog based on a wave, pulses, etc. Thus, an Encoder is an interface between a mobile mechanical device and a controller.
What is a Rotary Encoder?
In these devices, the reading is carried out on a disk, on whose face is the coding that allows discerning the angular position with great precision.
How does the KY-040 Rotary Encoder work?
The operation of the rotary encoder is very simple, when turning the axis of the incremental encoder two square signals called channel A (CLK) and B (DT) are generated , if the common pin is grounded and channel A and B with resistors.
