Notes

• Install a check valve in the air-pressure circuit so the gripper will not release a workpiece if air pressure drops.
• Reed switch bracket is attached.
• If proximity switches are used for direct detection of jaw stroke, purchase proximity switch brackets separately.
• Internal seals: nitrile rubber (fluororubber seals available as an option).
