Use the hex socket head
screws (M2.6×0.45,
length 5 mm [0.197 in.])
to mount the mounting
bracket into the mounting
holes on the back of the
sensor controller. The
tightening torque should
not exceed 32 N·cm
[2.83 in·lbf].
Use the small screws provided to
mount the sensor head.
The tightening torque should not
exceed 6.0N

Sensor head body
When the sensor head MSU-PH-

is supplied, the sensor head
body and mini clamp connector (male) are not yet connected. Follow
the procedure below to perform the connection.
1. Check that the connector cover (the part where lead wires are to be
inserted) is protruding from the connector body.
It cannot be used if it’
s flat and placed at the same level against the
body.
2. Cut the cable at the length required for the sensor head. Strip off
the cable sheath for 50 mm [1.97 in.] from the cable end, and
expose the lead wires. At this time, do not take off the lead wire
insulation.
3. Follow the instructions in the table below to insert the lead wires
into the hole in the connector cover. Look through the top of the
semi-transparent cover to check that the lead wires have been
firmly inserted all the way to the back. (Insertion length is about 9
mm [0.35 in.].)
Use caution in making the connections, since switching on the power
with wrong connections will damage the sensor head and controller.
4. Taking care to avoid letting the lead wires slip out from the
connector, use pliers or some other hand tool to crimp the cover
and connector body, and push the cover into the connector body.
Limit the crimping force to 980.7 N [220.5 lbf].
When the cover is flat and placed at the same level against the
connector body, the connection is complete.
5. In the same way, handle the sensor head relay cable PSUK-

mini-clamp connectors (male, female).
6. Check one more time that the wiring is correct.

To mount the sensor head and the power supply, switch, and
communication cable, align the lock lever position in the direction of
the arrow as shown in the figure, and push until the lock hooks on the
controller-side connector.
To remove, push down completely on the lock lever, take the
connector and pull it out. At this time, be careful to avoid applying
excessive force on the lead wires.
