A new series of sealed two-finger parallel grippers called DPG-plus is designed for the automated handling of components under extreme environmental conditions.
The sealed grippers have serrated guidance and round sealings which lets them produce high moments. The grippers are available in seven different sizes ranging in moment capacity from 30 (22 lbf.ft) to 160 Nm (118 lbf.ft). Units can be equipped with two strokes and a spring for additional grip force or a safety device for both OD and ID gripping, giving a total of 42 standard units to choose from. The DPG-plus has an IP67 rating. Pneumatic actuation results from an oval piston, which transfers the actuation to the jaws through a wedge hook system, thereby generating a considerably higher grip force than a round piston.
