SCHUNK PGL-plus-P Long-Stroke Pneumatic Gripper Review: Specs, Price and Applications
The SCHUNK PGL-plus-P is a pneumatic two-finger parallel gripper with a long jaw stroke and robust multi-tooth guidance. Opposing pistons drive the base jaws, and rack-and-pinion kinematics synchronize them for centric gripping.
It is IP64 protected as standard with sealed, metal-encapsulated base jaws, and it can be fitted with an integrated IO-Link sensor for stroke monitoring. With GripGuard technology, at least 80% of the gripping force is maintained during a pressure drop.
Quick Verdict
A versatile long-stroke gripper that handles varied part sizes with long fingers and adds modern features such as IO-Link stroke sensing and certified grip force maintenance.

Design and Operating Principle
Multi-tooth guidance spreads loads across many contact surfaces, giving high moment capacity so long fingers can be used without excessive wear. Combined with a long stroke, this lets one gripper cover a wide range of part widths.
IO-Link stroke monitoring reports jaw position continuously, enabling part-size verification and diagnostics without separate switches. GripGuard maintains at least 80% of the force if pressure drops, preventing parts from falling during an air failure.
Sealed, metal-encapsulated jaws and IP64 protection make the PGL-plus-P suitable for environments with dust and splashing, such as machining areas.
Integration and Selection
Check part width range, mass, finger length and robot acceleration, and confirm guide moments. Decide whether GripGuard is required for the safety concept.
Connect the IO-Link sensor to an IO-Link master and use stroke data in the program to verify parts and detect missed grips.
