How to order

Please install a check valve in the air-pressure circuit so that the gripper will not release a workpiece even if the air pressure drops down.
The length measuring sensor is a factory-installed option. Since optional parts such as cables vary depending on the signal output format, please contact the Kitagawa distributor when ordering the gripper with length measuring sensors.
When the jaw stroke is detected by the reed switches, mount reed switched on the grooves on the outer periphery of the product.
In case proximity switches are used for direct detection of jaw stroke, please purchase proximity switch brackets additionally.
