No matter where or how – the workpieces are always fast and securely gripped. Even if the power happens to fail. Speaking of speed – no one beats our magnetic heroes when it comes to being ready in a hurry. A short pulse of current is all it takes to get the magnetic grippers ready for use.

Uncomplicated, easy to handle and exceptionally strong – it's time to add the invisible force of magnetism to your production!

Your advantages – Your benefits

  • High holding forces for reliable part handling in compact automated systems
  • Actuation via 24 V voltage supply saves energy and simplifies the connection and the wiring
  • Workpiece accessibility from five sides free from interfering contours
  • Low weight for high dynamics in challenging applications
  • Reliable maintenance of holding force for process-safe use even in emergency-stop scenarios

How does magnetic gripping work?

The function of the magnetic gripper is based on the combination of Alnico and neodymium magnets. To activate the system, an electric current pulse is conducted through the coil, which reverses the polarity of the AlNiCo magnet accordingly. The magnetic flux of the AlNiCo magnet passes the neodymium magnet in the deactivated state, and closes the magnetic circuit over the gripper base body made of steel. The workpiece is always held securely – this is ensured by the grippers' mode of operation, which is based on a combination of electric and permanent magnets and reliably maintains the magnetic flux even when deactivated.

Battery handling

In order to fill battery packs or trays, battery cells can be placed very close together.

Sheet metal handling

Digital, four-stage gripping force regulation enables the gripping and separation of very thin steel sheets.

Raw part handling

A customized pole extension facilitates simple gripping of round material.

Motor handling

For assembly purposes, various quantities of electric motors can be handled simultaneously.
