Connecting the sensor head connection cable
●
For GT2-P***/PA***
1
Insert the sensor head connection cable 
into the cable connector on the relay 
connector cable.
2
Secure the connector with the sensor 
head connection cable screw.
●
For units other than GT2-P***/PA***
1
Insert the sensor head connection 
cable into the cable connector of the 
sensor head.
2
Secure the connector by rotating the 
grooved portion.
To disconnect the sensor head connection cable, reverse the steps above.
■
Connecting the amplifier
●
DIN rail mount type
1
Remove the lock cover of the connector of the sensor head 
connection cable, and insert the sensor head connection cable 
into the connector on the side of the amplifier until it clicks.
2
Put the lock cover on the connector, and lock the lock cover.
●
Panel mount type
1
Remove the lock cover of the connector of the sensor head 
connection cable, and insert the sensor head connection cable into 
the connector on the back of the amplifier until it clicks.
2
Put the lock cover on the connector, and lock the lock cover.
■
Mounting the sensor head
●
Mounting directly to the jig
Before mounting the sensor head directory to the jig, create a hole in the 
jig. Attach the sensor head using the optional head mounting bracket 
sold separately. A mounting bracket is provided with the GT2-P12KF/
P12F/H12K(L)F/H12(L)F as standard. Attach it with the supplied nut.
NOTICE
•W
hen connecting the connector, be sure to insert it 
straight, and tighten it securely. (Recommended 
tightening torque: 0.4 to 0.5 N•m*)
If the connection is not tight enough, the connector 
may be loosened by vibration or other causes, 
leading to a connection failure.
(* After tightening it firmly by hand, use pliers or other 
tools to rotate it about 30° for further tightening.)
• When the head is attached to a moving part, and the 
cable will be repeatedly bent, ensure that the cable 
between the sensor head and relay connector does 
not bend. Instead, bend the sensor head cable 
connecting the relay connector and the amplifier.
