Absolute Encoders

Absolute rotary encoders measure actual position by generating  unique digital codes or bits (instead of pulses) that represent the encoder's actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4,096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.

Frequently Asked Questions about Absolute Encoders

What is an absolute encoder?

There are two types of encoders, incremental and absolute. An absolute encoder can track the exact position of the shaft at all times and can retain position when power is off. This is ideal for applications where positioning data is critical.

How does an absolute encoder work?

Absolute encoders track shaft position by 2 major methods. Some use optical techniques with ligh shining through or reflecting off a disc, while others use sensors to detect magnetic pulses. Absolute encoders provide unique values for each position of the shaft and therefore will provide position data upon startup without homing to an index position, unlike incremental encoders.

How do you select an absolute encoder?

To select the right absolute encoder for your application you will first need to know the communication protocal required. This is typically determined by the controller or drive you will use. Next, determine whether you need a single turn or multi- turn encoder. Lastly, select the mechanical mounting, resolution and ingress protection based on the exact details of your application.
