Cabling system specialized for high-end battery applications

Amphenol Industrial Products has upgraded its SurLok Plus high-current connector and cabling system with a quick-connect and locking system that boasts the high-voltage interlock loop (HVIL) safety feature as well as EMI shielding for noise immunity.

The company is targeting the SurLok Plus products as a reliable alternative to common compression lugs in high-end battery systems to ensure safety and proper operation. They are particularly suitable for use in hybrid and fully electric vehicles as well as in energy storage for commercial and residential battery storage systems.

The SurLok Plus compression lug is optimized for battery pack connectors operating at currents from 50 A to 400 A using a touch-safe interface. The connectors, which offer industry-standard crimp, screw, and busbar termination options, are easy to install and eliminate the need to purchase torque tools.

The upgraded SurLok Plus system offers a flexible, quick-lock, and press-to-release design to accommodate dimensional constraints. And, with RADSOK technology, it ensures quick mating. Overall, it significantly increases amperage while reducing insertion force, temperature rise, and voltage drop.

The high-current cabling system is IP67-rated and comes in an unsealed configuration. But there is also a version that provides environmental sealing to protect the system from external elements.
