● Environmental conditions

To use the GT2-70 Series properly and safely, do not NOTICE install the GT2-70 Series in the following locations. Use

of this equipment in an improper environment may cause equipment failure.

Locations outside

Locations with high humidity, a large amount of dust, or poor ventilation

Locations where the temperature rises excessively due to direct sunlight, etc.

Locations near corrosive or flammable gas

Locations where the GT2-70 Series is directly subjected to vibration or impact

Locations where water, oil or chemicals may come into contact with the GT2-70 Series

Locations where static electricity may easily occur

Noise countermeasures

Installation near a source of electrical noise such as a power source or a power cable may cause malfunction or failure of the equipment. Adopt appropriate countermeasures against noise by using a noise filter or wiring cables in separate ducts, attaching insulation to the amplifier or the sensor head, etc.

Handling of the sensor head

The GT2-70 Series and peripheral devices are precision machines. Do not drop, or cause any other impact to these devices. Doing so may cause damage or malfunction.

Do not apply weight greater than what is listed below to the spindle. Do not apply rotational torque. Otherwise the spindle may break.

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.

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.

Tightening the nut while fixing the sensor head may lead to damage.

The tightening torque for mounting bracket A (OP-76874), mounting bracket C (OP-84396), and the nuts supplied with GT2-H12K(L)F/H12(L)F/P12KF/P12F is between 5 and 7 N•m

NOTICE (the recommended tightening torque is 5 N•m). Apply tightening torque between 15 and 18 N•m (20 to 23 N•m when using the GT2-A32/A50) to head mounting bracket D

(OP-84327). Use the wrench that matches the nut width.

Care must be taken not to damage the dust boot when tightening.

4 Rotate the dust boot so that the side line is straight. (Models other than GT2-PA12K/PA12)

Check with the spindle pushed in.

NOTICE

If the dust boot is not straight, it becomes easier to

damage when the spindle is moved.
