Smiths - Inductive Speed Sensor

Smiths Inductive speed sensor ideal for use with Smiths speedometer or other speedometers that require a pulse signal.

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
