BoardLock™ Connectors

Amphenol Sine Systems BoardLock™ connector family combines flanged or flangeless, 180° straight or 90° right-angle pin-oriented, wire-to-board versatility with the proven reliability of the A Series™. The A Series is an environmentally sealed thermoplastic connection system with a maximum current rating up to 100A. Featuring a compact, durable, low-profile, and lightweight design, this connector family is perfect for power or data signal applications. All BoardLock product lines accept A Series components and are comparable with other industry-standard mating connectors.
