52-Pos. Card Edge Connectors

meritec 52 Position Card Edge Connectors

Meritec’s 52 position Card Edge Connector was designed for a unique application. The application required a connector that would allow the daughter card to be inserted from the top of the connector or from the side of the connector. The side angle entry requires a custom lead in feature on the daughter card. Typically only 50 contacts are used in this latter application. The end contacts on each row are usually not configured into the overall design of the PCB when side insertion of the PCB is required. This dual row card edge connector is available in both surface mount and thru hole mount.
