The gold flash finish on the brass contacts handles the mating cycle count of a field-serviceable connector without the cost of a heavy gold plate; for environments with frequent reconnects or corrosive atmospheres, the flash layer provides adequate protection for the expected service life of a D-sub in an enclosure. ## Right-Angle Solder Termination for Board-Edge Mounting The 0.590\" (14.99 mm) backset spacing sets the distance from the board surface to the mounting flange — a dimension that must match the panel cutout and the mating receptacle's shell length. The 4-40 threaded inserts on the housing flange accept standard D-sub jackscrews for mechanical retention against vibration and cable strain.","metaTitle":"TE 5745990-3 AMPLIMITE HD-20 D-Sub Plug, 9-Pos R/A","metaDescription":"TE Connectivity 5745990-3 AMPLIMITE HD-20 D-Sub plug, 9 positions, right-angle solder, gold flash contacts, rated 6A/125V.
