The advent of the microprocessor created a demand for economical position sensors which could deliver longer operating life in custom-designed packages to fit specialized applications.In Duncan's 35 successful years, its custom-engineered and precision-manufactured potentiometers have been meeting this demand in applications as varied as agriculture and x-ray equipment.

  Duncan's thick film conductive plastic sensors stand up to heavy wear, exposure to chemicals and high-temperature operating environments. They are found on diesel engines for Caterpillar,in memory seat sensors for General Motors and as internally mounted sensors in hydraulic/pneumatic cylinders in Sweden.

  Duncan's line has grown to include small, low-cost modular kit and light-duty enclosed shaft encoders which incorporate our proprietary monolithic phased array opto IC (ASIC) technology.These devices are ideal for high volume applications in computer peripherals, motors, office and factory automation, medical instruments, automotive and related markets. Duncan has combined potentiometric and optical encoding technologies into unique sensing packages. Typical applications include servo motors, disk and tape drives, printers, plotters, medical equipment panel controls, instrumentation,robotics and process controls.
