Magnetic Grippers
Schmalz - The Company Magnetic grippers provide safe gripping of ferromagnetic workpieces by using the magnetic field of an integrated permanent magnet.

The magnet is moved with compressed air to activate and deactivate gripping. Magnetic grippers are operated with pneumatic valves.
The gripper does not require a voltage source for this purpose.
Vacuum Knowledge Advantages of magnetic grippers:
• Safe gripping with a permanent magnet is possible without voltage source
• Control of permanent magnet with compressed air and vacuum

Vacuum Suction Cups Typical areas of application:
• Handling of ferromagnetic workpieces
• Handling of blanks and perforated plates as well as sheet metal parts with
drilled holes/breakouts or complex shapes
• Support of vacuum gripping system in highly dynamic handling of sheet
metal parts
Special Grippers

Vacuum Grip- ping Systems Needle Grippers

The needles are pressed into the workpiece and herewith the gripping process is realized. The needles are ejected pneumatically.
The needles are extended at an angle to ensure reliable gripping of the workpieces. Once the gripping process is complete, the
Mounting Elements needles are retracted either through spring force or pneumatically.

Advantages of needle grippers:
• Safe handling of non-rigid materials or materials with an unstable shape
• Different shapes for unique operating conditions
Vacuum Generators • Selectable needle diameters and adjustable strokes

Typical areas of application:
• Handling of porous and/or non-rigid workpieces, such as textiles, insulating
and foam materials, fiber composites such as carbon and glass fiber, fleece
Valve Technology or felts, carpets, filters, fabric, styrofoam as well as metal foams

Switches and Monitoring

Thin glass gripper
Filters and Connections The thin glass gripper is a special gripper for the extremely dynamic and gentle handling of sensitive workpieces in automated or

semi-automated processes. It reduces the dynamic and static forces on workpiece through the optimized dimensioning and distribution
of suction positions.

Benefits of thin glass grippers:
Services • Significant reduction in damage rate for the thinnest workpieces (less than
0.1 mm thick)
• Full-surface gripping with low vacuum level
• Suction area made from mark-free PEEK to avoid glass surface contamination
Contact Typical areas of application:

• Thin glass grippers are used in the manufacture of TFT displays, smartphones
or tablets. The special gripper is also suitable for contamination-free
handling without compromising downstream processes such as coating.
