Note: All values typical, and quoted at 10N applied force unless otherwise stated. Force dependant on actuation interface,

mechanics, touch location, and measurement electronics.

The Ohmite FSR series exhibits the unique characteristic of

dynamic resistance related to the amount of applied force.

In general, the more force applied to the surface of the

sensor, the lower the resistance. The resistance change

is inversely proportional to the applied force. Typical

force-sensing resistors are characterized for Human-

Machine Interface (HMI) or Machine-Machine

Interface (MMI) applications with a sensing range

from circa 20g to 5Kg. Specific device character-

istics will depend on the size, shape and materials

used in construction. Force-sensing resistors are

intended for applications where a delta in applied force

is to be detected. They are not intended for high accu-

racy or specific weight measurement applications.
