*1 Value when the ambient temperature is 20 °C 68 °F.
*2 Representative value at the centre of the measuring range. Please note that the measuring force varies by the installation state of the dust boot. This is a representative value when using the GT2-PA12KL/PA12L with a pressure of 0.06 MPa. The measuring force varies depending on the air pressure used. For details, see table 1.No dust boots are used with the GT2-PA12KL/PA12L.
*3 Contacts are available as options sold separately.
*4 Including the relay connector.
