F303 Low Cost Axial Force Sensor

The F303 is aimed at the volume OEM user who requires a reliable high quality axial sensor at a low price for low accuracy compressive force measurement in equipment. It is manufactured from stainless steel and sealed to IP65 for long life in typical industrial operating conditions. The sensor is designed for simple mounting on a smooth flat surface.

Each sensor is labelled with its output for full range. A calibration certificate is not supplied as standard.

We are happy to design variants of this loadcell to meet your specific requirements. Please consult our engineering department.

Details of our other loadcell families can be found in the Product Guide.

  1. AL = Applied load.
  2. RL = Rated load.
  3. Temperature coefficients apply over the compensated range.
  4. The load must be applied directly through the central loading axis.


The loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 7-2-4C.

Excitation + = Red, Excitation - = Blue, Signal + = Yellow, Signal - = Green, Screen = Orange.

The screen is not connected to the loadcell body.

When this loadcell is rationalised the resistors are housed in a capsule located in the loadcell cable 100mm from the free end. Capsule dimensions are Ø10mm by 57mm.
