HotPot (Linear) Membrane Potentiometer

HotPot (Linear) Membrane Potentiometer

Essentially, the HotPot membrane potentiometer is a resistive element, which comprises a conductive resistor, a sealed encasement and a simple wiper assembly. A membrane potentiometer can also function as a voltage divider.

The HotPot (Linear) Membrane Potentiometer is a three-wire system with two resistive output channels and an electrical collector channel.

By pressing a wiper down onto the top circuit the HotPot (Linear) Membrane Potentiometer will produce the desired electrical output. The "wiper" is a non-conductive mechanism that depresses the top circuit actuating the potentiometer from the outside of the element. The top and bottom circuits of the HotPot (Linear) Membrane Potentiometer are separated by 0.15mm (0.006″) of spacer adhesive build-up and contact between the circuit occurs by pressure (usually 1-3 Newtons) from the wiper on the top circuit, pushing down until the top circuit connects with the bottom circuit to create a potentiometric output.

The construction of the wiper design can adapt to any application because most materials can serve as the wiper: plastics, metals, sliders, rollers, wheels, etc. Also, the HotPot can also be manually (hand) actuated.

The datasheet for the HotPot (Linear) Membrane Potentiometer is shown below, for more information contact us using the details above.
