SCHUNK MPZ Pneumatic 3-Finger Centric Gripper Review: Specs, Price and Applications
The SCHUNK MPZ is a compact pneumatic three-finger centric gripper for small workpieces. T-slot finger guidance gives precise gripping even under high moment loads, and the compact design keeps interfering contours to a minimum.
Finger positions can be monitored, including with the FPS system that distinguishes several grip positions. Optional AS/IS versions keep a minimum grip if air pressure drops, and air can be supplied hose-free or via screw connections.
Quick Verdict
A small, precise centric gripper for miniature round parts. FPS monitoring makes it particularly useful when several part sizes or orientations must be distinguished.

Design and Operating Principle
Three jaws closing synchronously centre small cylindrical parts such as pins, caps, bushings and lenses on the gripper axis. For precision assembly, that automatic centring removes positional error from the feeder.
FPS (flexible position sensor) monitoring measures where the jaws stop, so the controller can detect different part diameters, a missing part or a part gripped incorrectly. This turns the gripper into a simple inspection device.
Grip force maintenance keeps small parts from being dropped if air fails, protecting downstream equipment and preventing loose parts in the machine.
Integration and Selection
Check part mass, finger length and accelerations; small grippers are sensitive to long or heavy fingers. Select AS or IS based on inside or outside gripping.
Plan FPS evaluation in the PLC or robot controller to verify part size and presence.
