Membrane PotentiometersMembrane potentiometers are resistive elements or carbon position feedback sensors with a sealed encasement and a non-conductive simple wiper assembly that connects the top and bottom circuit. By pressing the wiper down on the top circuit to close the connection with the bottom circuit, the linear sensor produces the desired electrical output. The membrane potentiometer can also be actuated through manual (hand) control. Typical applications for membrane potentiometers are: piston-driven motion sensor tracking on chairs or seats; hydraulic motion/tilts, robotics, door & window sensors, medical hand instruments, finger actuated music, and more.
