The M521 electro holding magnets are used for specific and electrically controllable holding or loosening of loads in manipulating and conveying equipment.
The holding magnets are available in 2 versions:
- Holding (H):
Electro holding magnets that start magnetizing and hold workpieces only once power has been supplied.
- Loosening (L):
For this purpose, permanent adhesive magnets are used that release workpieces only when energy is supplied.
