ELECTRO PERMANENT MAGNETS FOR AUTOMATION

ELECTRO PERMANENT MAGNETS FOR AUTOMATION A magnetic gripper is a transmission device that can clamp ferromagnetic charges by a strong electro permanent magnet. The “double magnet” technology uses the electric current only during the magnetising and demagnetising phase. The effective force is generated by permanent magnets. In the event of a power failure, the workpiece [...]

Electro Lifting Magnets for Thin Steel Sheets

Electro Lifting Magnets for Thin Steel Sheets SIMPLE OPERATION Depending on the thickness of the steel strip, the force during the PICK-UP phase can be set via a 4-position switch. This ensures that only one steel strip is picked up. Once the sheet is loose from the stack, it immediately switches to FULLMAG = 100% [...]
