SPEED SENSOR INSTALLATION NOTES
- The Smiths speed sensor EMP34-1(KIT) is an inductive proximity type, normally used to detect a steel target eg. Bolt heads on a propshaft or driveshaft flange.
- The installer needs to provide a suitable mounting bracket such that the air gap, after the sensor has been installed, remains constant under all driving conditions.
- The nominal air gap (distance between sensor face and the target) should be set at 2.0mm.
- Bolt heads on a propshaft flange (or other target) must be equi-spaced, to ensure the sender generates a constant frequency.
- The sensor is supplied complete with a approx/
- The sensor is supplied with an approx.190cm cable which 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
