Preparing the Sensor

WARNING: Do not use the studs if there is any danger that a person may be
injured by the protruding metal.

1. Remove the label from over the sensor’s socket (part A) (see Figure 2).
2. There are two ways to attach the sensor to the bracket. Choose either a or b.

a. Studs—It is easier to install and adjust the sensor using the M5 studs.

However they will protrude about 20mm (3/4") below the bracket after
installation. Apply removable thread locker to the two studs. Screw the studs
into the underside of the sensor.

b. Screws—Omit the studs. After the sensor is aligned in the bracket, use the

brass machine screws supplied to fasten it in place. The sensor will be flush
with the bracket when the installation is complete.

3. Remove the protective cap from the sensor connector on the cable. (Save the

cap to protect the connector, when the sensor is removed.)

4. Pass the instrument connector-end of the cable through the center of the gasket.
5. Plug the sensor connector firmly into the sensor. It fits one way only.
6. Push the gasket (part B) against the sensor (and onto the studs if applicable). Be

sure to orient the gasket so that the groove fits over the alignment tab on the
connector and the sensor’s socket. The screw holes in both the sensor and the
gasket must be aligned. (It may be helpful to hold the gasket in place with double-
sided tape.)
NOTE: The arrow on the gasket will face the same direction as the word
‘FORWARD’ on the sensor.
