Membrane Potentiometer - Accurate position measurement with low space requirement
107,00 kr
The resistance of this inexpensive membrane potentiometer changes linearly according to where pressure on the strip is applied, and it can therefore be used to accurately measure a position. The potentiometer can be activated directly by finger touch or with mechanical controls using sliding or rolling wipers. It has a thickness of just 0.5 mm and therefore requires very little installation space.
Used for:
The potentiometer is used for industrial controls, audio controls, and motion controls.
Details:
It is available with active lengths from 10 mm to 1000 mm. There is a range of standard stock sizes, and customised variants are available with low tooling costs. There is also a non-contact variant that is activated by a magnet. The service life is dependent on the slider implementation, but it is typically more than one million cycles.
Idea:
Design a lamp where the dimming is controlled by repositioning a magnet on the lampshade.
Try it:
Use an ohmmeter to test the functionality.
The sample:
The sample is glued to cardboard (see product photo) and has an active sensing area with a length of 50 mm.
All samples come with a laminated information card, which includes contact details for the supplier.
