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
    
        
            |  | >> 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). | 
        
            |  | >> 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. |
