GIMATIC DHG Series Pneumatic Parallel Gripper Review: Specs, Price and Applications
The GIMATIC DHG series is a two-jaw self-centering pneumatic parallel gripper designed for high-efficiency force transmission in a compact body.
It is double acting with optional springs for normally closed or normally open behaviour, comes in long-stroke and short-stroke versions, can be front-fastened with through screws and accepts magnetic or inductive sensors. NSF-H1 food-grade grease is available.
Quick Verdict
A flexible pneumatic gripper whose long- and short-stroke versions let one family cover both wide part ranges and high-force tasks.

Design and Operating Principle
The choice between long and short stroke is a classic gripper trade-off. A short-stroke version converts piston force more directly into jaw force, while a long-stroke version opens wider to accept larger or more varied parts, or to clear surrounding features during approach.
High-efficiency force transmission means less of the piston force is lost to friction in the drive, so more of it reaches the part. That allows a smaller, lighter gripper for a given task, which in turn leaves more payload for the robot.
Front fastening with through screws simplifies mounting on tool plates and multi-gripper heads, and the option of inductive sensors provides robust position detection in environments where magnetic sensors might be affected.
Integration and Selection
Pick short stroke for maximum force on consistent parts and long stroke for part families with varying widths. Then check the allowable finger length and moments for the chosen size.
Select NC springs where the part must stay held on air loss, and use sensors to confirm jaw position before each robot move.
