1 GT2-70-M-E High-accuracy Digital Contact Sensor GT2-70 Series Instruction Manual ■ Symbols The following symbols alert you to matters concerning the prevention of human injury and product damage. Be sure to read these messages carefully. Safety Information for GT2-70 Series ■ 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.

Models in GT2 series by KEYENCE America: Amplifier, Cable, Interface unit, Optional parts, Power supply unit, Sensor head, Software. 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 or 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. Samsung 6 Series User Manual• 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 GT2- H50/A50 (Material: NBR (attached when shipped)).) Attach the dust boot correctly. Neopost In-300 Series User ManualThe 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.
