FMA Series - Small Footprint Digital Force Sensor -Image

The FMA Series are designed to meet the customer’s need for a compensated, amplified force sensor which provides digital outputs, a variety of force sensing ranges, a small, cost-effective format, and enhanced durability and accuracy. The flexible design provides multiple standard configurations over a wide operating temperature range.



  • Multiple force ranges allow the customer to choose the force range to maximize sensitivity and improve system resolution/performance.
  • Smaller package allows for space constrained applications. 
  • Robust design provides enhanced durability in applications where overforce may exist.
  • Enhanced accuracy includes all errors due to force non-linearity, force hysteresis, and non-repeatability. 
  • Reduced Total Error Band enhances system performance.
  • Digital output enhances performance through reduced conversion requirements and the convenience of direct interface to microprocessors. SPI- or I2C-compatible digital output.
  • Diagnostic functions allow the user to determine if the sensor is working correctly by detecting if electrical paths are broken or shorted inside the sensor.
  • Selectable supply voltages provide customers with design flexibility.
