BEI Sensors

BEI Sensors specializes in speed and position sensors for extreme applications. Serving the industrial, military, aerospace and off-highway markets, BEI Sensors provides an extensive range of products from standard off-the-shelf to completely customized solutions for any challenging application. Backed by decades of experience, BEI designs sensors that offer uncompromising quality, performance, and reliability. The comprehensive product line includes optical and magnetic encoders, Hall effect sensors, potentiometers (wirewound, conductive plastic and hybrid), electronic interface modules, wireless modules, and a variety of product accessories. Specialized products for extreme applications include those for wash-down and corrosive environments, extended operating temperatures, high shock and vibration, wet and dirty operations and products certified for hazardous area use.

Rotary Optical Encoders

  • Rugged construction and years of field proven service makes BEI optical rotary encoders ideal for operating in harsh industrial environments
  • BEI optical encoders are available as incremental, absolute single-turn, and absolute multi-turn
  • BEI Sensors programmable encoders offer resolution flexibility to match changing needs while also saving on inventory costs and reducing machine downtime

Magnetic Encoders

  • Magnetic sensing technology is best for operations in very high temperatures and environments with extreme shock and vibration
  • Ideal applications for magnetic encoders include wind energy, tree harvesting, traction motors for rail equipment and pavement profiling

Hall Effect Sensors

  • Hall effect sensors meet customer needs for high performance, non-contact rotary position sensor solutions
  • This product line features a standard operational life of 35 million cycles while providing up to 6-turns with 2160 degrees of resolution and linearity of +/-0.5%
  • Capable of having redundant outputs, meeting up to IP69K sealing requirements and operating temperatures of 85 degrees C
