Molex KK 508 Connector
The Molex KK 508 Connector System is designed to provide reliable performance for low- to mid-range power applications, delivering up to 7.0A per circuit in wire-to-board configurations and 5.0A per circuit in board-to-board setups. Equipped with Glow Wire capability, the system meets stringent safety requirements, making it suitable for global use. The connectors feature a polarized mating geometry that ensures secure and correct connections, preventing mismating. For enhanced electrical reliability, the bifurcated terminals offer two independent contact beams, while the dual-cantilever terminals provide consistent electrical contact. Additionally, anti-snag terminals prevent damage during cable assembly, improving durability. With a standard 5.08mm pitch, the KK 508 system is versatile, accommodating various power needs. Its availability in multiple configurations, including top-entry, right-angle, and bottom-entry PCB receptacles, provides design flexibility, making it adaptable for a wide range of applications.
