MultiMag connectors are designed for small and compact applications in tight spaces. These include, for example, MultiMag 6 for applications such as USB connection and MultiMag 15 for general power and data transmission. These innovative magnetic self-mating connectors automatically discover connections and prevent tearing. They're ideal for products and environments where frequent connection and disconnection is a prerequisite, from medical devices and industrial automation to drones, robots, smart watches and data glasses.

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