Overview
VMA334
This FSR (Force Sensing Resistor) will vary its resistance depending on how much pressure is being applied
to the sensing area. A 2.54 mm male pinheader is provided making it easy to use it on breadboards.

Example
The value of the resistor is as example only. Practically, a resistor of about 220 k
Ω
should be used depending
on the application.
