Sensor wiring :
The sensor has 3 wires, a red one for power supply plus, a black one for power supply ground
and a green wire giving the speed information.
These three wires have to be connected with EGS pins 10,11 and 12 as follows :
EGS pin 10
EGS pin 11
EGS pin 12
This sensor has loose wires and does NOT have a sensor connector.
A good connection between sensor and EGS can be achieved in two ways :
use of shielded pair cable (2 central conductors + shield)
use of 3 twisted wires (of different colour)
Shielded pair cable :
If shielded cable is used, make sure that the mechanical strength of the cable and its
temperature specification is suitable for the application.
CENTRAL CONDUCTORS (INSULATED)
Connection of a 3 wire sensor with shielded cable
The first central conductor of the shielded cable has to be connected with EGS pin 10 (HOT
sensor input) on one end and with the GREEN wire on the other side. The second central
conductor of the shielded cable has to be connected with EGS pin 12 (sensor supply 8 Volt)
on one end and with the RED wire on the other side.
The shield has to be connected to EGS pin 11 (GND sensor input) on one end and with the
BLACK sensor lead on the other side.
MAKE SURE NOT TO CONNECT THE SHIELD TO
THE VEHICLE CHASSIS !
This would produce electrical noise on the sensor input and can lead to degraded operation.
