The Amphenol FCI DCO8W8P300H40LF is the 8-position power-only member of the DW series D-Sub, Combo family. It carries 8 power contacts in a single row, rated 40 A per contact at 300 V, in a through-hole solder-mount plug with gold-plated brass pins. The shell is steel with nickel plating, and the dielectric is UL94 V-0 thermoplastic. This is a dedicated power interconnect — no signal pins — built into the standard 4 (DC, C) - 8W8 shell layout.
Where It Fits and What It Does
This connector is designed for power distribution inside industrial control cabinets, power supplies, battery management systems, and similar equipment where you need to route 40 A per circuit through a D-sub shell. The board-side 4-40 flange mounts to a standard D-sub panel cutout, and the board lock holds the connector in place during soldering and against vibration in service.
40 A Per Contact — What That Means
40 A per contact is bus-level current for a D-sub shell. Each power pin is sized to carry the main DC rail or high-current AC line — not a signal, not a low-power control circuit. The single-row arrangement keeps the contact-to-contact spacing wide enough to handle the temperature rise at full load without derating the adjacent pins.
