Force Sensitive Resistor 0.5"

Product Code:
SEN-09375
£6.98 £5.82

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.

0.5" Force Sensitive Resistor

The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg. 

These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale.

Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly. There is a peel-and-stick rubber backing on the other side of the sensing area to mount the FSR.
