It uses outer shroud contacts that protect the signal pins during mating and guide alignment — a useful feature when the board stack is tight and the connector is out of sight. The dual-row layout with gold-plated contacts (8.00µin thickness) suits signal-level duty where corrosion resistance and reliable contact over repeated mating cycles matter. ## SMT Placement and Packaging for the Line This header is surface-mount only, packaged in Tape & Reel — it feeds directly into a pick-and-place line without a tray changeover. No through-hole variant in this order code, so the board layout must be SMT-only. ## Obsolete — Sourcing Strategy for the BOM Line If the design can tolerate a different stack height or position count, the broader DF12 series includes active variants worth reviewing. ## Mating Half and Fit Check The 50-position count and 0.50mm pitch are non-negotiable for the footprint — verify the receptacle order code matches these dimensions before committing the BOM. The outer shroud contacts are on the header side; the receptacle accepts the blade.","metaTitle":"Hirose DF12B(4.0)-50DP-0.5V(86) Header, 50 Pos, 0.50mm","metaDescription":"Hirose DF12 series header, 50 positions, 0.50mm pitch, 4mm stack height, SMT, gold contacts.
