Encoder and Sensor Product Overview


Rotary Through-Hole Optical Encoder - HS45

Optical Rotary Encoders

Incremental, absolute single-turn, and absolute multi-turn encoder models available in hollow shaft and shafted encoder body styles. Optical sensing technology offers the most precise, highest resolution encoders, which are extremely rugged for harsh and dirty environments. BEI Sensors Express Encoders® are available for quick delivery - with six package styles (four incremental and two absolute) to choose from providing over 2,000 different encoder configurations.

Rotary Shafted Magnetic Encoder - DHM5-CHM5-HHM5

Magnetic Rotary Encoders

Incremental, absolute single-turn, and absolute multi-turn models available in hollow shaft and shafted body styles. Magnetic sensing technology is ideal for operation in very high temperatures and environments with extreme shock. Check out the LP Series of low profile magnetic encoders for harsh environments.

Non-contact position sensor - hall effect

Programmable Encoders

Programmable encoders allow the user to choose a wide range of resolutions, reducing machine downtime and saving on inventory costs.


Non-contact position sensor - hall effect

Hall Effect Rotary Position Sensors

High performance, non-contact rotary position sensor solutions for resolving angular position with an analog output. Models available up to 6-turns with 2160 degrees of resolution.

Rotary linearcontact potentiometer

Rotary and Linear Potentiometers

Rugged contacting sensors available as wirewound, conductive plastic and hybrid technology in a range of single or multi-turn configurations up to 3600º (10-turns) of motion.
