  • Designed for hand or robotic actuation
  • In car ergonomic replication
  • Easily customized

About the ALF321 Gear Shift Force Sensor

The ALF321 gear shift loadcell measures gear lever forces required to achieve gear selection. An ergonomically designed gear knob senses the force from a human hand or a mechanical actuator. The three axis force components are represented by three pure loadcell output signals. The gear shift loadcell is supplied calibrated and ready to use, no in-situ calibration or mathematical computation is required.

Easy fitment is achieved with mechanical axis referencing and simple attachment to a male thread or adapter.

The gear shift loadcell, like all our automotive products, can be produced for environmental test chamber temperature requirements of -40 to 80°C.

We are happy to design variants of this loadcell to meet your specific requirements.

The standard range is manufactured in aluminium.

Notes
1. AL = Applied load.
2. RL = Rated load.
3. Temperature coefficients apply over the compensated range.
4. Values apply to all axes unless otherwise specified.

Connections
The ALF321 is fitted with 2 metres of PVC insulated 12 core screened cable type 7-1-12C. The screen is not connected to the loadcell body.
