Installing the “CAR” speed sensor
The wheel speed sensor for phonic wheel belongs to the “non contact” devices
and it needs a ferrous metal trigger to pass the sensor face.
When mounting the sensor, please firmly install it on a self-made iron bracket and
make sure that the distance between the sensor and the phonic wheel is included
between 0.5 and 2 mm (1 mm is the optimum value). Once the sensor has been
installed, please plug the sensor’s Binder connector in your MyChron 3
Plus/Gold/Gold XG.
