Festo’s DHxS pneumatic grippers set new industry standard

Festo’s (www.festo.com) three-point, parallel, angle and pneumatic grippers, DHxS, set new standard in performance as they offer optimized overload protection and gripping force retention. Designed with integrated sensor slots, the compact grippers offer various forward-looking features to ensure precision and reliability. The integrated fixed restrictor serves as a safety buffer, preventing damage caused by excessive forces and protecting from overloading during high-speed gripper motions. Integrated sensor slots, on the other hand, deliver cost-effective stroke sensing through sensors SMx. In addition, the compression spring-assisted gripping force retention of DHxs grippers offer more security in case of pressure failure, while T-slot guides increase the resistance of gripper jaws to torque. Festo DHxS pneumatic grippers With the double-acting piston drive, the parallel and three-point gripper delivers maximum repetition accuracy and stable kinematics. For flexible mounting, Festo also offers a vast array of mounting options in the form of fitting, threaded and centering holes. Featuring light weight aluminum housing, the parallel and three-point DHxS grippers are also equipped with an integrated receiving hole for the pneumatic piston. The force produced by the linear motion is transferred to the low-backlash gripper jaws through lever kinematics. This eliminates the need for separate synchronization, since the lever is in mesh indirectly with the two gripper jaws through a piston rod. Meanwhile, the pneumatic pistons of the radial and angle grippers act on the gripper jaws, which are mounted on the gripper jaw guide’s pivot, via a slotted guide system. Much like with the parallel and three-point grippers, this also implies that there is no need for added synchronization.
