Rotary Encoders

RS have a great range of Rotary Encoders that are suitable for a wide variety of electronics projects. Our Rotary Encoders are ideal for engineers, technicians and even beginners and are great value for money from trusted brands such as Bourns, Omron, TE Connectivity and Wurth Elektronik.

Rotary encoders are electro-mechanical devices that convert the angular position of a shaft to either analogue or digital output signals. The types of rotary encoders include mechanical rotary and optical rotary and can be installed using brackets specially designed for mounting in machinery.
