How encoders work

Supplier: Plant Control and Automation
21 October, 2011

A Shaft Encoder is an electromechanical transducer, which converts a rotary position into an electronic signal suitable for providing input data to a vast range of electronic control devices.

Shaft Encoders are being used for an ever-increasing variety of mechanical applications.

Following are just a few examples:

  • Measuring the length of raw material during a winding process, then again when the material is cut to size for final use.
  • Determining angular positions when synchronising machine movements, such as those found in packaging machines.
  • Monitoring the position of products on a conveyor.
  • Positioning of indexing tables, stacker cranes, etc.
  • Tracking the position of automated robots, and their arm movements.
  • Some of the more unusual applications include satellite tracking, road surface analysis and automobile suspension studies.
