For over four decades, BEI Duncan Electronics has been a manufacturer of linear and rotary position sensors. Using various combinations of innovative, high durability, conductive plastics and specialized resistive wire , our products have met many demanding applications involving harsh environments and long life requirements. Solutions include capabilities exceeding 10 million cycles and operating temperatures to 300 degrees Celsius.

BEI Duncan produces industry's most cost-effective and reliable "contact" and "non-contacting" sensors (precision potentiometric devices; position, indicating, resistive or voltage reading devices, including encoders) for a broad range of applications. From automotive to avionics, consumer to robotics, instrumentation to heavy equipment, BEI Duncan products fill an important niche wherever accuracy, reliablility, space-conscious devices are needed.

Our Products include

	ROTARY POSITION SENSORS >> Contacting >> Non-Contacting Duncan's Precision Rotary Sensors are classified by type of resistive technology; wirewound coil, hybrid coils and conductive plastic (thick-film) elements. Sensor type significantly influences circuit efficiency and determines performance, reliability and cost effectiveness (see type description for selection of most appropriate materials).
	LINEAR POSITION SENSORS >> Contacting BEI Duncan Electronics’ linear conductive plastic, potentiometric solutions feature many of the same options as our rotary devices. Linear products offer options capable of over 1 meter of travel and 1 million meters of operational life at temperatures to 300 degrees Celsius. These devices can be incorporated into hydraulic/pneumatic cylinders, installed on circuit boards, or simply mounted to mechanical assemblies. As with any of our sensor solutions custom/adapted linear solutions are available with many of the same options as our rotary solutions. Element and Contact Assemblies are also available.
	CUSTOM SOLUTIONS >> See Solutions BEI Duncan Electronics’ experienced capabilities in design, engineering and manufacturing allow us to provide innovative adapted solutions and complete custom solutions to meet unique position sensor requirements. We offer individual element and contact components – typically provided jointly as an element and contact assembly – that fit directly into your existing design, thereby reducing packaging costs and optimizing space. Our custom packaging solutions are evidenced in many products that have been engineered to fulfill unique needs for sealing, vibration exposure, cycling durability, high temperature, and other unusual requirements.
	OPTICAL ENCODERS >> Optical Encoders BEI Duncan Encoders offer an excellent choice of Modular, Kit and Enclosed Shaft Encoder designs ideally suited for a wide variety of applications. We offer our traditional responsiveness and packaging strengths across its encoder product line and capabilities.

Product Category :

EI Duncan Electronics’ rotary potentiometric 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 devices can be installed on circuit boards or simply mounted to mechanical assemblies. Termination options include integral connectors and surface mount or flying leads that allow customers to more easily choose a connector. As with any of our sensor solutions, a wide variety of cost-effective, custom/adapted solutions 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.
