BoardLock™ AT/ATM Series™ Connectors

Amphenol Sine Systems' BoardLock header 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™ environmentally-sealed thermoplastic connection system with a maximum current rating up to 25 A. Featuring a compact, durable, low-profile, and lightweight design, perfect for power or data signal applications in heavy equipment, transportation, industrial, off-road, and harsh environments.

All BoardLock header product lines accept A Series components and are compatible with other industry standard mating connectors. The snap-in board features allow for rapid placement and the enclosed latch-receiver design benefits potting and overmold applications. When combined with the economical A Series positive polarization and available coding options, mismating occurrences are dramatically reduced.

Amphenol Sine's engineering teams can provide unique mixed-power and signal arrangements, 90° or straight PCB pins, or custom flange mount designs to reduce overall connector size and save space.
