The Molex 0903270320 is a 20-position, dual-row IDC receptacle from the Picoflex PF-50 90327 series, designed for mass-termination to 26-28 AWG ribbon cable. The housing is white and features a feed-through design, allowing the ribbon cable to pass through the connector body for daisy-chaining to additional positions without cutting the cable.
Termination and Wire Handling
IDC termination to 26-28 AWG ribbon cable is the defining assembly method here. The wire slots in the receptacle body displace the insulation and make contact with the tin-plated female sockets in a single press operation. The feed-through feature lets the ribbon cable run straight through the connector body, so multiple receptacles can be ganged on the same cable run without individual cable stubs. This is common in parallel bus topologies where each drop needs a connector at the same cable segment.
The header is typically a through-hole or surface-mount board-mount part, while this receptacle stays on the cable end.
