Challenges
In battery-swapping systems, removable-battery equipment, mobile devices and other high-frequency connection applications, connectors often need to support both charging/discharging and signal transmission. Repeated mating, angled insertion and removal, cable flexing and equipment vibration can cause loose connections or terminal damage. Rain, moisture and accidental contact with live terminals also create higher requirements for ingress protection and operational safety. Meanwhile, different equipment structures and space constraints require flexible mounting, cable-routing and locking options.
Positioning
The KR 2+6 Series is a family of 50A hybrid power and signal connectors designed for battery swapping, removable batteries and mobile equipment. The series combines high mating durability, water resistance, touch-safe protection, vibration resistance and ease of operation. Multiple plug, receptacle, mounting and locking configurations provide flexible connection solutions for different equipment designs.
Features
50A Hybrid Power and Signal Connection
Two power contacts and six signal contacts integrate power transmission and signal communication into a single interface, reducing connector count and simplifying system design.
Reliable Water and Touch Protection
The battery-side receptacle and mated connection can meet IPX7 requirements. IPXXB touch-safe power contacts help reduce the risks of water ingress and accidental contact with live parts.
High Mating Durability
Supports up to 3,000 mating cycles, making it suitable for battery swapping, charging and removable-battery applications requiring frequent connection.
Resistance to Angled Mating and Vibration
The robust structure withstands angled insertion and removal as well as equipment vibration, reducing the risk of terminal damage, loosening and unstable contact.
Intuitive and Secure Locking
The locking version features an intuitive latch that guides operation and helps users confirm secure engagement. A non-locking version is also available for fast connection and disconnection.
90° Cable Exit and Flex Durability
The 90° cabinet-side plug is suitable for space-constrained installations and can withstand up to 5,000 cable-flex cycles, improving durability under repeated bending and handling.
Multiple Standard Configurations
Diamond- and square-flange receptacles, together with locking and non-locking plugs, accommodate different mounting spaces, cable-routing requirements and operating preferences while reducing the need for customization.
