Magnetic Safety Lock generates more than 1,500 N at 0.3 A.

Press Release Summary:

Able to electrically lock and hold door closed with up to 1,500 N of force, Magne 1A can be used together with Eden door position sensors to provide protection from dangerous machine movements. Magnet provides locked/unlocked indication with no current peaks on activation. Use of M12 connectors enables several Magne units and Eden sensors to be connected in series. Operating from -20 to +50°C, Magne 1A has no moving parts and is IP67-rated for harsh environments.

Electrical Magnet MAGNE Generates up to more than 1500N at 0.3A

Jokab Safety has introduced a new electrical magnet developed for safety applications in combination with the Eden door monitoring switch.

The Magne 1A can electrically lock and hold a door closed with up to 1500 Newtons of force and when power is turned off no magnetic material will stick on the magnet surface.

Magne 1A can be used together with Eden door position sensors providing protection from dangerous machine movements. Use of M12 connectors makes it easy to connect several Magne units and Eden sensors in series, enabling control and monitoring by either a Pluto safety PLC or a Vital safety module. Via the connection cable it is also possible to obtain an indication signal informing if the Magne unit is locked or not.

Electrical locking of doors and hatches to production applications that are sensitive to unintentional/unnecessary interruptions.
