Hall Effect Sensors and Technology - one of the latest additions to BEI Sensors’ product line - meet customer needs for high performance, non-contacting rotary postion sensor solutions. Our non-contacting design features a standard operational life of 35 million cycles. These Hall Effect sensor devices provide up to 6-turns with 2160 degrees of resolution and linearity of +/-0.5%. Hall Effect sensor solutions can accommodate applications that require an interface to the end of a shaft or that must fit over a shaft. Standard Hall Effect Rotary Position Sensor models are capable of providing redundant outputs, meeting IP66/67 sealing requirements and 85 degrees Celsius operating temperature, with option to 150 degrees Celsius. Custom/adapted solutions are available. These include packaging, electrical angle, linearity, termination, redundant outputs, custom transfer functions, PWM output, CAN Bus output, switch function, environmental and more.
BEI Sensors rotary potentiometers and contact sensor solutions offer a range of single or multi-turn configurations up to 3600º (10-turns) of motion. These rugged, reliable contact sensors can meet IP66/67 sealing requirements and provide operational life exceeding 10 million cycles. A variety of terminations are available, including integral connectors and flying leads. Adapted and custom solutions for are also available.
BEI Sensors linear potentiometers offer capabilities of over 1 meter of travel and 1 million meters of operational life at temperatures up to 300ºC. These linear position sensor devices can be incorporated into hydraulic/pneumatic cylinders, installed on circuit boards, or simply mounted to mechanical assemblies. As with any of our BEI potentiometer solutions, we offer a wide variety of standard and custom/adapted solutions for demanding motion control applications.
An optical encoder is an electro-opto-mechanical sensor that provides angular position information to a counter or controller. The optical encoder uses a sensing technology that relies on the interruption of light to detect the encoder's movement. Optical sensing technology is the most precise and offers the highest resolution of the position sensing technologies. 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, or absolute multi-turn.
