SPEED SENSOR INSTALLATION NOTES  

 

PLEASE READ THESE INSTRUCTIONS THOROUGHLY BEFORE COMMENCING INSTALLATION.

 

1. The CAI speed sensor EMP34-1(KIT) is an inductive proximity type, normally used to detect a steel target eg. boltheads on a propshaft or driveshaft flange.

 

2. The installer needs to provide a suitable mounting bracket such that the airgap, after the sensor has been installed, remains constant under all driving conditions.

 

3. This sensor generates a 12 volt pulse each time it detects a steel object in front of the sensing face.  A yellow led located at the rear end of the sender will illuminate each time the sensor detects a target.

 

4. The nominal airgap (distance between sensor face and the target) should be set at 2.0mm.

 

5. Boltheads on a propshaft flange (or other target) must be equi-spaced, to ensure the sender generates a constant frequency.  

 

6. The sensor should be connected as follows:

 Brown wire – connect to 12 volt positive supply from the ignition switch

 Blue wire – connect to ground.

 Black wire – speed signal, connect to white/black wire on the speedo harness                          Continued >>
