Pneumatic Toggle Grippers

OG-A 2-Finger

OG-A is a two-finger toggle gripper with a high grip force and non-reversible mechanism, suitable for heavy industrial applications.


  • High energy density.
  • 180° jaw opening allows for part clearance without having to back the gripper out of the workspace
  • Driving mechanism guided along the entire stroke
  • The toggle mechanism provides non-reversible gripping in the opening and closing positions, even without air pressure
  • The opening stroke is adjustable.
  • A special finger mounting system allows fine adjustment of the gripping point.
  • Mounting from two sides in two screw directions for versatile and flexible integration.
  • Integrated permanent magnets for direct monitoring of piston movement.
  • Slots for mounting and positioning of magnetic-field sensors.
  • Air supply via screw connection or hose-free direct connection.
