F321 Gear Shift Loadcell

The F321 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. Please consult our engineering department.

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