Rotary encoders | Choosing the right rotary encoder
The incremental rotary encoder measures an angular displacement with respect to a reference position. After a power failure, the data processing system must wait for the encoder to send the information corresponding to the reference position in order to correctly exploit the angular displacement information. Incremental rotary encoders are designed using different technologies, each with its own advantages and disadvantages. The most common technologies used...

How to choose this product
rotary-encoder

Rotary encoders are devices that provide angular position feedback for motion control applications. They provide information such as angular speed, position, displacement, direction and acceleration.

Applications

Rotary encoders are used to provide motion control feedback for rotational applications. Mounted on the shaft of an electric motor, they control the position, acceleration, speed or direction.

Technologies

There exist two types of rotary encoders: incremental and absolute. Incremental models indicate the change in position of a rotating shaft from a known reference point. Absolute versions provide an absolute position rather than the change in position.

How to choose

The type of output and the environment in which your rotary encoder will perform can help in narrowing down your choices. Defining measurement needs will enable you to select between absolute and incremental types, and between optical and magnetic models.

Advantages

- Motion control
