Board-to-Board Header, 64 Positions, 0.100" Pitch
The Amphenol BERGSTIK II 87052-464HLF is a dual-row, unshrouded board-to-board header with 64 positions on a standard 0.100" (2.54mm) pitch. It carries 5 A per circuit at 110 V — a signal-level rating suited for logic boards, not a power bus. The through-hole solder termination and push-pull fastening make it a straightforward fit for prototyping or production runs where the mating half is a matching unshrouded receptacle.
Key Specs and What They Mean for Fit
The 0.100" pitch and 0.100" row spacing match the legacy 0.100" grid — the footprint is a standard dual-row pattern of 64 plated through-holes. The unshrouded design means no keying or polarization; the header relies on the board layout and the mating receptacle's alignment for correct orientation. Tin plating on both the mating and post surfaces keeps cost low but limits the connector to a few dozen mating cycles — not for frequent reconnection or corrosive environments.
Sourcing and Lifecycle
The 87052-464HLF carries an Active lifecycle status from Amphenol — no end-of-life notice, no last-time-buy window. No official replacement or cross-reference is on record; the 64-position count and 0.100" pitch are the BOM line match points.
