A digital hall effect sensor for use as a wheel speed sensor. It can be used with the speed sensor (MVSS and SVSS) inputs on Adaptronic ECU's along with many others including DTA, Motec, Syvecs and more. Suitable also for cam triggering.

The sensor is of the proximity type and will often work fine with an existing ABS trigger ring or other metal toothed trigger or ring somewhere in the drive train.

The sensor should run from ignition power but will work with any voltage input from 4.5 to 24vdc. The output is of the "open collector" type meaning that when the sensor detects a tooth on the ring it's output will be closed (or pulled) to ground. Most ECU's have an internal pull-up resistor on their speed inputs to allow the use of this type of sensor.

It comes in a sealed plastic body. Dimensions are:
Length = 35mm (not including wires)
Diamater of cylinder = 18mm

Wiring details:
Red trace = + supply (4.5 to 24vdc)
Black wire = - ground
White trace = output

For launch control with an Adaptronic you need only the one speed input from an un-driven wheel connected to an SVSS input. For gear dependent boost with Adaptronic you need either a differential speed signal or a sensor like this on each driven wheel connected to the MVSS inputs. For traction control you typically need all 4 wheels monitored, or as a minimum you can use differential speed and a un-driven wheel speed. Using an ABS ring on those wheels with one of these sensors mounted above it (rather like a crank angle sensor) is the simplest way of achieving a speed signal.
