A2543 is a 2.54 mm connector system. Compare the drawing-based specifications and construction options below, then identify the required configuration for quotation.
Connector construction
Select the housing, contacts and mating connector together. The available circuit counts and materials depend on the specific drawing, rather than one range covering every variant.
Separate male and female housings are documented in single-row and dual-row layouts, together with multiple through-hole board profiles. Housing and board materials include profile-specific PA66, PBT and PA46; tabled position options differ substantially between profiles.
