BEI Duncan Electronics’ rotary potentiometers and contacting position sensor solutions offer customers a range of options that can resolve up to 3600 degrees (10-turns) of motion, meet IP66/67 sealing requirements, and provide operational life exceeding 10 million cycles. Our product line also has options for resolving up to 3600 degrees (10-turns) of rotary motion with redundant outputs for high reliability. These rotarty potentiometer devices can be installed on circuit boards or simply mounted to mechanical assemblies. Termination options on these rotary sensors include integral connectors and surface mount or flying leads that allow customers to more easily choose a connector. As with any of our BEI position sensor solutions, we offer a wide variety of cost-effective and custom/adapted solutions. These are available to address customer specific requirements for angular resolution, electrical angle, CAN Bus or PWM outputs, switch function, custom transfer functions, linearity, termination, operational life, environmental requirements, packaging requirements, and much more. We can also provide components that allow customers to package Element and Contact Assemblies directly into their existing package, thereby reducing packaging costs and space requirements. For further assistance on custom configurations, please contact us.
