^*1 Value when the ambient temperature is 20 °C.
^*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-PA12K/PA12 with a pressure of 0.25 MPa. The measuring force varies depending on the air pressure used. For details, see table 1.
No dust boots are used with the GT2-PA12K/PA12.
^*3 Contacts are available as options sold separately.
^*4 Including the relay connector.
