What this 0.40mm-pitch shielded plug does that an unshielded sibling cannot
Its 0.016" (0.40mm) pitch packs 30 circuits into a board-edge footprint roughly 12mm wide, which suits camera modules, display interconnects, and sensor arrays where every millimeter of PCB real estate is allocated. The shielded construction and solder retention features are what set this member apart from the unshielded DF40C-30DP-0.4V(51) — the metal shroud around the contacts bleeds EMI before it reaches the signal lines, making this the pick for RF or high-speed digital paths inside a compact device. The 1.14mm height above board keeps the plug low-profile, and the mated stacking heights of 1.5mm and 3mm tell the board layout engineer exactly which receptacle height to pair it with — the 1.5mm stack for ultra-thin builds, the 3mm stack when component clearance underneath the mezzanine matters more.
30 positions at 0.40mm pitch — the board layout constraint
At this pitch, routing a trace between two pads on a single layer is not possible with standard PCB fabrication — expect to break out on inner layers or use micro-vias. The dual-row arrangement with 30 positions means 15 contacts per row, so the footprint needs a staggered via pattern to keep the escape routing clean.
Active production — no last-time-buy pressure on this BOM line
RoHS compliant per, with no exemptions that would complicate EU market shipments.
Mating half and stack height selection
This plug mates with the DF40 series receptacle (outer shroud contacts, 30 positions, 0.40mm pitch). The mated stack heights of 1.5mm and 3mm are achieved by pairing this plug with the corresponding receptacle height variant — the 1.5mm stack uses a shorter receptacle, the 3mm stack a taller one. Confirm the receptacle order code against the desired stack height before committing the BOM. The shielded shroud on both halves maintains continuous EMI coverage around the mated pair.
