Flatshifter Shift
The Flatshifter 'Shift' is a strain gauged shear beam force sensor that is designed to replace the OEM gear knob on a sequential gearbox to enable clutch less up and down shifting using a Flatshifter gear shifting system or any ECU ignition-cut and throttle blip or similar type functions.
The 'Shift' system utilises a full bridge strain gauged shear beam load cell that causes the force applied to the gear knob cover to act at the instantaneous centre of rotation of the gear lever making the device insensitive to hand position, unlike similar inferior sensors usually sold that use bending beam load cells. The device is supplied complete with cover, cable and connector.
An amplifier module is supplied to excite the bridge and amplify the bridge output. Several amplifier options are available to suit individual applications.
Gear Knob Specification:
- Force Range Bi-directional 1-12Kg (10-120N).
- Gauge resistance: 350 Ohms
- Excitation voltage: 5 Volts
- Temperature range: -10 to +50c
- Max overload: 150% FS
- Tightening torque: 16 Nm
- Attachment Thread: M10 x 1.5 or 1/2in dia. for Quaife gearboxes
- Cable: 1 metre four core shielded cable fitted with Binder IP40 connection.
- Weight: 168 Grams

Amplifier Module Options
1. This version connects the gear knob to the Flatshifter shifter system as an alternative to the shift rod. The trigger level is set via the adjusting knob on the amplifier module.
2. Ref. 2.5 volts Amplifier Module.. This version gives a 2.5 volt output with no load on the load cell with the voltage rising above or falling below 2.5 volts depending on if the gear knob is pushed or pulled.
3. Ref 0 volts Amplifier Module. This gives 0 volts output with no load on the load cell and gives a positive or negative output depending on if the gear knob is pushed or pulled.
4. Dual Input Amplifier Module. ECU input signal wires for up shift or downshift are switched to ground at a pre-set trigger level depending on whether the gear knob is pushed or pulled. The trigger level is adjustable via an adjusting knob on the amplifier module.
Please note options 2, 3, and 4 require a 12 volt DC supply and ground connection.
