What is thinpot Film Potentiometer Sensor

Embrane Potentiometer

The potentiometers are customizable membrane position sensors with a flexible,

ultra-thin, light weight profile. It has 2 standard formations, strip and ring. Its low power

requirements and linear output make it the ideal position sensor for many applications.

1. Features:

4.2 standard type in Ring formation

5. Standard connection options

For single channel potentiometer the standard connection is a 3-wire system with two

resistive output channels and one collector channel. It can also be a 2-wire system with one

resistive output channel and one collector channel.

• Solder Tab

• Square male pins

• Female Receptacles with plain housing

• Female Receptacles with Lock housing

The Potentiometer Sensor consists of a polyester film with excellent mechanical properties, a highly conductive material and a nanoscale pressure sensitive material. The top layer is a flexible film and a composite pressure layer on the top. The bottom layer is a flexible film and a composite conductive wire. Both through the double-sided adhesive paste to isolate the sensing area. When the induction zone is compressed, the lines that are disconnected from each other through the top layer of the pressure-sensitive layer conduction, the port resistance output value changes with the pressure.

Film Potentiometer Sensor Applications
