Rosenberger MagCode® systems provide short-circuit-proof, self-finding magnetic connections of 12 V and 24 V applications. They are used, for example, for trickle charging of batteries in vehicles with longer standing times, such as in cars, vans, motor homes as well as motorcycles and boats - especially also in emergency vehicles. They are also used to supply power to mobile devices, such as external coolers or headlights.

MagCode® PowerSystem
The MagCode® Magnetic Power System is a magnetic connector system for 12 V and 24 V.
Magnets in the PowerPort and PowerClip ensure contact is made between the two parts of the connector as well as providing a switching function. The flat contacts only carry power when the moveable plate in the port is magnetized by the magnets in the clip. Totally short-circuit-proof, the MagCode® Power System is designed to avoid other metal objects or permanent magnets inadvertently energizing the contacts.

MagCode® PowerSystemPro
The MagCode® Magnetic Power System Pro is a magnetic connector system for 12 V and 24 V with mechanical twist lock. Important are higher separation forces,  higher current load and no arcing problem.
MagCode® Power System Pro features an additional twist lock mechanism for applications where greater separation forces and higher current load are necessary. In addition, the twist lock function guarantees switching will not occur before the outside contact has been closed – therefore eliminating potential arcing problems.
