The Rosenberger MagneticUSB is an innovative connection series. All standard USB connectors can be very easily connected to computer or mobile devices thanks to intelligent magnet technology. It can also be disconnected very quickly for optimally protecting USB connections.

Since USB is a widely used standard with different connector formats (Mini-B, Micro-B etc.), Rosenberger makes various USB compatible magnetic connectors available to suit USB 2.0 devices and applications.

Break-Away Function
This is designed to break the connection safely should the plug or cable be subjected to an acute tensile force (intentional or unintentional), therefore avoiding risk of injury to the user and damage to the connectors or devices. The deliberate removal of the plug is also fast and simple.
