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