*1 Value when the ambient temperature is 20°C 68°F.
*2 This is a representative value at the center of the measuring range when using GT2 with a pressure of 0.25MPa. The measuring force varies depending on the air pressure used. For details, please refer to the catalog or the user manual.
*3 In the case where a mounting bracket D is used with GT2-A32 and GT2-A50, the double amplitude becomes 0.75 mm 0.03".
*4 The contact is included with the sensor.
*5 Including the relay connector.
