1
Insert the tightening sleeve into the mounting bracket from the side
with a depression, and loosely tighten with the nut.
2
Insert the sensor head into the tightening sleeve, and tighten the nut
with a wrench.
3
Secure the sensor head with M4 screws.
Mount the sensor head with the model label on top. For GT2-P12K(L)/
P12(L)/PA12K/PA12, mount so that the head indicator is on top.
4
Rotate the dust boot so that the side line is straight. (Models other
than GT2-PA12K/PA12)
Check with the spindle pushed in.
● Mounting to the mounting holes
The mounting holes on the side of the GT2-H32(L)/H50/A32/A50
unit can be used to install to the side of a table or other surface.
■ Installing the Air Tube
● Compatible air tube
Use a tube with the following specifications.
● How to Attach/Detach the Air Tube (GT2-PA12K/PA12)
• Attaching the air tube
Insert the air tube into the air supply hole on the relay connector.
• Detaching the air tube
To detach the air tube, pull the air tube in the direction of the arrow,
as indicated in the figure below.
● How to Attach/Detach the Air Tube (GT2-A12K(L)/A12(L)/A32/A50)
• Attaching the air tube
Feed the tubing into the socket until it bottoms out (about 1/2").
The socket will ensure a tight seal around the tubing.
NOTICE
• If the sleeve is inserted from the wrong side, the
sensor head cannot be secured.
• Strongly tightening the nut without the sensor head
inserted may deform the tightening nut.
• Head mounting bracket B cannot be used in
combination with head mounting bracket C (OP-
84396) or head mounting bracket D (OP-84327).
NOTICE
Tightening the nut while fixing the sensor head may
lead to damage.
• Apply a tightening torque of 5 to 7 N m (the
recommended tightening torque is 5 N m). Use the
wrench that fits the width of the nut.
• Care must be taken not to damage the dust boot
when tightening.
NOTICE
• Never apply tightening torque over 1.4 N m.
• Care must be taken not to damage the dust boot
when tightening.
NOTICE
If the dust boot is not straight, it becomes easier to
damage when the spindle is moved.
NOTICE
• Roughness of the mounting surface may cause the
sensor to tilt, and sufficient accuracy may not be
obtained. When performing a high-accuracy
measurement, use a jig to mount the sensor head.
"Mounting directly to the jig" (page 4)
• Apply tightening torque between 1.2 and 1.5 N m.

NOTICE
• For best results, cut the end of the tube at a right
angle, and ensure that the outer perimeter is not
damaged, and that it still maintains a circular cross
section.
• If the tube is not properly inserted, air leakage may
result.
• After attaching, pull on the tube to make sure it is
secure.
• Use a urethane tube. Make sure it also has a
bending radius of at least 50 mm.
NOTICE Before detaching the tube, be sure to stop any air flow.
