The Amphenol 86832-452HLF is a 52-position, dual-row unshrouded header from the BERGSTIK® II series, built on the standard 0.100" (2.54 mm) pitch grid. Tin-plated contacts (100.0 µ" on the mating surface) and a UL94 V-0 rated black insulator suit it for general-purpose signal interconnects inside enclosed equipment.
The 0.100" (2.54 mm) pitch and 0.100" (2.54 mm) row spacing place this header on the industry-standard grid — the footprint matches legacy prototyping layouts and common 0.100" receptacle strips. The 5 A per-contact rating with tin plating is a signal-level ceiling; tin contacts are suited for occasional mating cycles, not frequent disconnect/reconnect duty in a production harness. The 110 V rating is the working voltage between adjacent pins at the stated pitch. The overall contact length of 0.525" (13.34 mm) with a 0.325" (8.26 mm) mating length and 0.100" (2.54 mm) post length defines the board-to-board stack height — the mating receptacle must be selected to match this engagement depth.
