Flex Sensor 114.3mm (4.5") RoHS Compliant

Flex Sensor 114.3mm (4.5")

A simple flex sensor 114.3mm (4.5") in length.

As the sensor is flexed, the resistance across the sensor increases.

Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove.

The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend).

Flexiforce Pressure Sensor 45.36kg (100lbs)
RoHS Compliant

Flexiforce Pressure Sensor
45.36kg (100lbs)

This is a piezoresistive force sensor. The harder you press, the lower the sensor's resistance. Pressing hard, the resistance changes from infinite to ~300k. The sensor itself is thin and flexible, but the resistance does not change while being flexed. Resistance changes only when pressure is applied to the round area at the end of the sensor. Used as a presence sensor (someone standing), weight sensor, pressure sensor (impact testing), etc.

SoftPot Membrane Potentiometer 100mm
RoHS Compliant

SoftPot Membrane Potentiometer 100mm

These are very thin variable potentiometers. By pressing down on various parts of the strip, the resistance linearly changes from 100 Ohms to 10,000 Ohms allowing the user to very accurately calculate the relative position on the strip. Can be used as an accurate positional indicator for CNC head positioning, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many other applications.
