SKU: SF-SEN-09673

A compact force sensitive resistor (FSR) from Interlink Electronics with a 4 mm (0.16″) diameter active sensing area. The resistance changes based on applied pressure — from over 1 MΩ with no pressure down to approximately 2.5 kΩ at full force — making it easy to detect touch, squeeze, and weight...

SKU: SF-COM-11620

A compact linear-taper slide potentiometer rated at 10 kΩ and 0.1 W. This small slider features solder tab connections, a 20 mm travel distance, and two mounting holes for easy installation. Key Features Linear Taper – Smooth, proportional resistance change across the travel range Solder Tab ...

SKU: SF-SEN-09375

This is a force sensitive resistor with a round, 0.5" diameter, sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be ...

SKU: SF-SEN-08679

A thin, flexible membrane potentiometer that senses finger or stylus position along a 200 mm strip. Pressing anywhere on the strip varies resistance linearly from 100 Ω to 10 kΩ, providing accurate positional data for user interfaces, sliders, and control inputs. The connector uses 2.54 mm (0.1"...

SKU: SF-SEN-13637

A simple breakout board for measuring moisture in soil and similar materials. The two large exposed pads act as probes — functioning as a variable resistor where higher moisture means better conductivity, lower resistance, and a higher signal output. This version includes a 3-pin screw terminal p...
