Specifications
■ Sensor head
GT2-P***/PA*** cannot be connected to amplifier units purchased before April 15th 2014.
● Pencil type (GT2-PA12K/PA12 are air cylinder types)
*1 When the surrounding temperature is 20°C.
*2 This is a typical value at the center of the measuring range. The measuring force varies depending on the mounted condition of the dust boot.
For GT2-PA12K/PA12, this is a representative value when using 0.25 MPa. The measuring force varies depending on the air pressure used. See table 1 for more details.
There is no dust boot for GT2-PA12K/PA12.
*3 When using an M8 oil resistant cable (GT2-CHP2M/5M/10M) as the sensor head cable.
*4 The contact is a separately sold option.
*5 Including the relay connector.
Note: Cannot be used with amplifier units purchased before April 15th, 2014.
● Box type
*1 When the surrounding temperature is 20°C.
*2 This is a typical value at the center of the measuring range. The measuring force varies depending on the mounted condition of the dust boot.
*3 The contact is a separately sold option.
● Air cylinder type
*1 When the surrounding temperature is 20°C.
*2 This is a typical value at the center of the measuring range. The measuring force varies depending on the mounted condition of the dust boot.
*3 Connect an air tube to the exhaust valve so that no foreign materials enter from the valve.
*4 When using mounting bracket D (OP-84327) with GT2-A32/A50, vibration is 0.75 mm.
*5 The contact is a separately sold option.
