16-Aug-Schunk-Gripper-PGN-Plus-360Schunk introduced its PGN-Plus-E and PGN-Plus P, two mechatronic grippers that improve upon the company’s original PGN-Plus gripper line. According to the company, its PGN-plus-E (pictured left) is the world’s first digitally controlled mechatronic gripper. It’s patented multi-tooth guidance provides higher moment capacity, a continuous lubrication pocket in the guide contour, and wedge-hook kinematics with a high surface coverage in all stroke positions. Powered by a brushless DC servo motor, the 24V gripper is controlled by digital I/O. Up to two gripping positions can also be monitored by means of an additional M8 standard connection.

The PGN-Plus-P gripper (right) provides permanent lubrication is through continuous lubrication pockets in the guidance. It also has an enlarged drive piston area which increases grip force so that higher workpiece weights can be handled. In addition to the larger piston, the wedge drive mechanism has been redesigned for lower friction and greater surface area which transmits more energy to the jaws creating even more grip force than previous generations.
