Connecting and Mounting the Sensor Head
■ Names of parts of the sensor head
* Not included in the GT2-P12KL/P12L.
● GT2-H12K(L)(F)(LF)/H12(L)(F)(LF)/H32(L)/H50
● GT2-A12K(L)/A12(L)/A32/A50
■ 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
• When 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.
