Amphenol L177DD50P D-Sub Connector Plug Gold Plated

Amphenol L177DD50P is a 50-position D-sub plug (male) with gold-plated contacts, designed to mate with a matching D-sub receptacle to form a robust 50-conductor interface in compact equipment enclosures. As part of Amphenol's DD-series, the L177DD50P employs a double-density contact layout that places 50 signal conductors across the familiar D-sub footprint, preserving standard mating geometry, alignment, and insertion feel when connected to the corresponding socket. Gold plating on the contacts provides low contact resistance and improved corrosion resistance, helping maintain reliable electrical performance through repeated mating cycles and across a range of ambient conditions. With the L177DD50P designation, buyers can identify a plug variant with 50 pins in the DD configuration, intended to interconnect devices in a modular, high-pin-count system using Amphenol's established D-sub ecosystem. Compatible DD50 receptacles exist in Amphenol’s product line, enabling a straightforward combination of plug and socket to form a 50-position interconnect used in various industrial and lab environments.
