Figure 22 – Magnetic pickup wiring and dimensions
The magnetic pickup available from Rexnord or other
magnetic pickups can be installed by completing the
following steps.
1.
If using customer’s magnetic pickup,
remove 1.25” NPT pipe plug and have it
machined to accommodate sensor. If the
magnetic pickup is supplied by Rexnord, the
1.25” NPT pipe plug has already been
modified.
2.
Verify the target bolt is located in the 12
o’clock position by using the 1.25” NPT
hole in the clutch housing. If necessary,
rotate the clutch hub so that the target
sensing bolt is vertical and can be seen thru
the hole. The inching drive motor can be
jogged to accomplish this.
3.
Move the locking nut of the magnetic
pickup to the top of the threads. Thread the
magnetic pickup into the machined hole in
the pipe plug until the bottom of the sensor
makes contact with the target sensing bolt.
4.
Using a dial indicator (or other measuring
device), adjust the location of Rexnord’s
magnetic pickup so there is a 2-3 mm (0.08”
- .012”) air gap between the magnetic
pickup and the target (Figure 23). A 2-3
mm air gap will take approximately 2 turns
of Rexnord’s magnetic sensor. Tighten the
lock nuts. The air gap of other sensors can
be set in a similar manner.

target
