Board-to-board unshrouded header
The 77311-424-32LF is the 32-position single-row member of Amphenol ICC (FCI)'s BERGSTIK® unshrouded header line, designed for board-to-board stacking. Tin-plated square pins on 0.100" (2.54 mm) pitch carry 3 A per contact. The through-hole solder termination and push-pull fastening suit it for parallel-board spacing where a shrouded header would block airflow.
Pitch, plating, and pin count
The 0.100" (2.54 mm) pitch and tin-on-tin contact system keep per-contact cost low for high-density signal routing. The single row of 32 positions loads all positions; the unshrouded profile mates with standard 0.100" pitch receptacles without keying.
Thermoplastic housing and flammability
Black thermoplastic insulator carries UL94 V-0 rating. The operating range spans -65°C to 125°C, covering most industrial and telecom enclosures without derating.
