Handling of the sensor head

The GT2-500 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 GT2-500 Series with high accuracy, do not use the GT2-500 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 9) 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 air supply 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 GT2P12K(F)/P12(F): OP-87859 (Material: Fluororubber). For GT2-H32/A32: OP-84459 (Material: NBR (attached when shipped)). For GT2-H50/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.

When loosening the screw with the hexagonal

wrench, insert the long end of the hexagonal NOTICE wrench into the hex screw and rotate the small end

with your hand.

Do not forcibly tighten the hex screw.

Cannot be used with GT2-P12KF/P12F/H***/A***.

Mounting on the side of a surface

When mounting to the side of a GT2-P12K(L)/P12(L)/PA12K/PA12/ H12K(L)/H12(L)/A12K(L)/A12(L) unit, use the optional head mounting bracket B (OP-76875).

Notice the correct angle of the tightening sleeve.

 

If the sleeve is inserted from the wrong side, the sensor head cannot be secured.

Strongly tightening the nut without the sensor head NOTICE inserted may deform the tightening nut.

Head mounting bracket B cannot be used in combination with head mounting bracket C (OP84396) or head mounting bracket D (OP-84327).

2 Insert the sensor head into the tightening sleeve, and tighten the nut with a wrench.

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

• Apply a tightening torque of 5 to 7 N m (the

NOTICE 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.

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.

• Never apply tightening torque over 1.4 N m. NOTICE • 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.

 

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.
