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.
