Membrane Potentiometer

A Membrane Potentiometer provides variable resistance based on the touch or press location along its length. Its thin and durable structure ensures reliable performance for position tracking tasks.

These sensors are valued for their linear or rotary sensing capabilities, offering a straightforward and precise method for detecting position changes.

Reliable and Compact Position Sensing

The Membrane Potentiometer provides accurate and repeatable position feedback with a thin, durable design.

How Membrane Potentiometer Works

A Membrane Potentiometer operates as a position sensor that varies its electrical resistance based on the location of a touch or press along its surface. When pressure is applied, the contact point creates a change in resistance, which corresponds to the position along the membrane. This enables reliable and linear position tracking.

Key Features

Compact and Thin Design: Easily integrates into space-constrained systems.
Linear or Rotary Tracking: Supports both linear position and rotational feedback.
Durable Structure: Designed for long-term, consistent operation with minimal wear.
Precise Feedback: Offers repeatable and smooth position detection across the sensing range.

Applications

Matrix Array Sensors are suitable for tasks that require detailed and distributed force detection, including:

Linear Position Sensors: Detecting the position of sliders or touchpoints along a straight path.
Rotary Feedback Systems: Measuring angular positions in compact rotary mechanisms.
User Interface Controls: Used in devices requiring position-sensitive input like volume sliders or control pads.
