About the ALF304 Brake Pedal Force Sensor

The ALF304 is a compact, low profile loadcell for measuring brake pedal application forces. The loadcell is robust in construction with a maximum force range of 2500N (250kgf). Its multi-hole fixing allows simple attachment to any shape pedal using screws or cable ties. The low profile stainless steel design maintains the brake pedals ergonomic geometry.

If you require other force ranges the ALF322 or ALF323 may be suitable.

We are happy to design variants of this loadcell to meet your specific requirements. Versions can be manufactured for higher temperature operation. Please consult our engineering department.

All standard ranges are manufactured in stainless steel.

Notes
1. AL = Applied load.
2. RL = Rated load.
3. Temperature coefficients apply over the compensated range.

Connections
The ALF304 is fitted with 2 metres of flexible polyurethane jacketed 4 core screened cable.
Excitation + = Red, Excitation - = Blue, Signal + = Yellow, Signal - = Green, Screen = Orange.
The screen is not connected to the loadcell body.
