Using three twisted wires we can achieve sufficient amount of noise rejection provided the
wires are twisted at least 20 turns per meter.

Connection of a 3 wire sensor with twisted wires
The sensor wires are connected to EGS pins 10 and 11 and 12 the same way as described
above.
Be sure to correctly observe sensor polarities,
AS WRONG CONNECTIONS WILL DESTROY THE
SENSOR !
5.2.2.c Magneto Resistive sensors
Sensor installation :
Magneto resistive sensors generate a square wave current with a fixed amplitude changing
between 7 mA and 14 mA.
The Magneto Resistive sensor currently in use (p/n 4202485) is pictured below. On the
sensor's body, there is a small plastic triangular position sign. Make sure the position sign on
the sensor points in the direction of the movement of the gearteeth (teeth rotation).
