Rotary Encoders

Rotary Encoders are devices that convert a motion into an analogue or digital signal. These devices are electro-mechanical sensors that monitor the position of the shaft or axle and convert it into the signal readable for digital devices. Rotary Encoders are also known as shaft encoders.
Rotary Encoders can be divided into 2 main types:
· Absolute – Digital Absolute encoders produce a unique digital code for each angle of shaft. These type of encoders maintains position information when a system power is off. The position of encoder is available again on applying power. The relationship between the encoder value and the physical position of the controlled machinery is set at assembly, the system does not need to return to a calibration point to maintain position accuracy.
Types of absolute encoders:
o Mechanical
o Optical
o Magnetic
o Capacitive
· Incremental – These encoders accurately records the changes in position of the shaft but does not power up with fixed relation between encoder state and physical position. The point where the counting begins depends on the external device counting system and not the position of the encoder. To provide useful position information, the encoder position must be referenced to the device to which is attached.
Rotary Encoders are commonly used in many applications that require precise shaft unlimited rotation. It means they can be used across industries such as robotics industry, electronic industry, and machinery production but are also very popular parts of many household devices.
