The PWG-plus is compact and robust due to the oval piston drive, the strong aluminum housing, and the almost wear-free T-bar drive.  Depending on the application, it can also be equipped with an ID/OD spring safety device.  Numerous accessories are available, including inductive proximity sensors and magnetic sensors. The PWG-plus gripper jaws and gripper mounting holes are capable of mounting directly to certain SCHUNK compensation units, attachment valves, and quick-change jaw systems. There are many advantages to using the PWG-plus gripper, including the design of outrigger workpiece supports due to threaded connections and centering sleeve options. There are also a variety of gripper sizes and gripping torques.
