The 56 positions, all loaded, give you a 28-pin-per-row density that suits wide parallel data buses or dense I/O banks. The overall contact length of 1.040\" (26.42 mm) breaks down into a 0.820\" mating tail and a 0.120\" solder post — the long mating pin is designed to reach through a mating receptacle and still give good wipe, while the short post keeps the through-hole solder joint compact on the back side of the board. ## Deployment Context The unshrouded header and UL94 V-0 rated black thermoplastic housing suit it for internal board-to-board connections inside equipment enclosures where the connector won't see casual handling or cable strain. The push-pull retention means the mating receptacle needs its own locking feature if vibration is a concern — this header relies entirely on the friction of the pin-receptacle interface.","metaTitle":"Amphenol 87901-456HLF BERGSTIK II Header, 56 Pos","metaDescription":"Amphenol 87901-456HLF BERGSTIK® II unshrouded header, 56 positions, dual row, 0.100\" pitch, tin-plated contacts rated 5 A.
