What is an Encoder?

Simply put, an encoder is a communication device that controls the motion of an operating device. Encoders can help determine the speed or position of a motor, or other moving equipment.

As automation in many industries and applications spreads rapidly, encoders help to maintain speed and position in electromechanical equipment, a vital process when accuracy, repeatability and precise motion is necessary.

Encoders are used widely throughout many applications, including automotive, laboratory and medical equipment, robotics, factory automation and electric motors.

Traditionally, optical encoders were used most widely in motion control, but as the need for a more robust, rugged sensing solution increased, magnetic encoding technology has started to surpass optical encoders as a better solution for difficult environments.
