IP67 Enclosure Rating
To maintain an IP67 enclosure rating for GT-A10/A22, the following
must be satisfied:
• Firmly connect tubing with 2.5 mm inner diameter to the exhaust
port until it bottoms out.
• Ensure that the tube end is free of dirt or water.
• Tighten the screw of the exhaust valve with a torque of 0.5 to
0.6 N
y m. If the screw is loose, the IP67 rating cannot be
guaranteed.
By loosening the screw of the exhaust valve, you can
change the exhaust port angle.
Adjustment of Spindle Movement Speed
To adjust the spindle movement speed, install the optional speed
controller (OP-82133) between the cylinder and the air supply.
• To ensure proper operation, install the speed
controller within 0.5 m of the cylinder.
• Install the speed controller in the direction indicated
by the above figure. The speed controller will not
operate if installed in the reverse direction.
Specifications
*1 The read value at the detection center under an ambient
temperature of 23°C and a response time of 100 ms.
*2 The operating force (typical value) at the center of the
movable range of the installed sensor head when supplying
air. Note that the detectability varies according to the
mounted condition of the dust boot. Do not mount the dust
boot on GT-A10L/A22L.
*3 Includes the connector cable (2 m).
