•The GT2-P12KL(F)/P12L(F)/PA12K/PA12 spindle can rotate a maximum of about 4.5°. When using an offset contact (OP77683) or similar, if pressure in the rotational direction is applied to the contact, the measurement position may change.
•Although the GT2-PA12K/PA12/H12K/H12KF/H12/H12F/ H32/H50/A12K/A12/A32/A50 has a protection rating of
NOTICE |
IP67, avoid using it immersed in water or in places where |
|||||||||||
liquid such as oil may come into contact with it. |
||||||||||||
• |
Although the GT2-P12K(F)/P12(F) has a protection rating of |
|||||||||||
|
IP67G/NEMA Type 13, some types of oil may damage the device. |
|||||||||||
• |
If dust, metal powder, or similar becomes attached to the sliding part |
|||||||||||
|
of the sensor head, mechanical responses may become slow. If this |
|||||||||||
|
happens, replace the dust seal with a replacement dust seal (OP- |
|||||||||||
|
87932). Refer to the instruction manual included with the replacement |
|||||||||||
|
dust seal (OP-87932) for instructions on how to replace the dust seal. |

■ Other precautions
●Effects of surrounding air temperature
To use the GT2-70 Series with high accuracy, do not use the GT2-70 Series in an environment in which the surrounding air temperature changes sharply.
It will take about 40 minutes for the 12 mm type, and 60 minutes for the 32 mm/50 mm type for the internal temperature to stabilize when the surrounding air temperature has changed by 10°C.
●Warming up
The circuit is not stable immediately after the power turns ON, which sometimes causes the indicated value to gradually fluctuate. Wait for about 5 minutes when using the 12 mm type and about 10 minutes when using the 32/50 mm type after the power turns on before starting operation.
●GT2-PA12K/PA12 (See illustration 1 for the pneumatic circuit)
•This model uses a single-acting cylinder. The internal spring will return the sensor head to its home position.
•The air supply hole cannot be removed.
•Use an air filter, mist separator, etc. to provide clean dry air. Empty the drainage from the filter regularly, before it exceeds the specified line.
•Before connecting the air tube to the air supply hole, be sure to blow plenty of air through the pipes (flushing) to remove any foreign matter.
•Make sure that the air pressure of the supplied air is constant and in the range of 0.24 to 0.26 MPa. Use a precision regulator to control the air pressure. If the air pressure is below 0.24 MPa, the spindle may not extend fully.
•When supplying air (with the spindle extended), up to 3L/min of air will be emitted from the tip of the dust seal.
•The measuring ability of the device changes according to the air pressure of the air supply. Refer to "Specifications" (page 14) for details.
●GT2-A12K(L)/A12(L)/A32/A50 (See illustration 1 for the pneumatic circuit)
•This model uses a single-acting cylinder. The internal spring will return the sensor head to its home position when air pressure is removed. DO NOT supply air to the exhaust valve.
•The air cylinder cannot be removed.
•Use the regulator to supply the stable air pressure to the sensor head.
•Use the air filter and mist separators to supply dry air. Empty the drainage from the filter regularly, before it exceeds the specified line.
•Make sure that the air pressure of the supplied air is constant and in the range of 0.25 MPa to 0.5 MPa.
•The coupling socket and the exhaust valve that are supplied with the
air cylinder are dedicated for this product. They cannot be removed.

●Power supply
•Noise superimposed on the power supply may cause malfunction. Be sure to use the DC stabilized power supply provided with an insulation transformer.
•In the case of a commercially available switching regulator, be sure to ground the frame ground terminal or the ground terminal.
●About dust boot
When the dust boot of the sensor head is damaged, use an optional dust boot sold separately (For GT2-P12K(F)/P12(F)/H12K(F)/H12(F)/A12K/A12: OP-84332 (Material: NBR (attached when shipped)). For GT2-P12K(F)/P12(F): OP-87859 (Material: Fluororubber). For GT2-H32/A32: OP-84459 (Material: NBR (attached when shipped)). For GT2H50/A50 (Material: NBR (attached when shipped)).) Attach the dust boot correctly. The dust boot may deteriorate, depending on the environment it is used in. In this case, replace the dust boot regularly.
* Do not use the dust boot on the GT2-P12KL/P12L/PA12K/PA12/H12KL(F)/H12L(F)/H32L.

■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.
•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.
NOTICE (* 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.
● For units other than GT2-P***/PA***
1 Insert the sensor head connection
cable into the cable connector of the |
|
sensor head. |
Arrow |
2 Secure the connector by rotating the grooved portion.
•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, NOTICE leading to a connection failure.
(* After tightening it firmly by hand, use pliers or other tools to rotate it about 30o for further tightening.)
