Right-Angle D-Sub for Board-Edge I/O
The TE Connectivity 5-1393480-5 is a 9-position D-Sub receptacle from the AMPLIMITE HD-20 series, built in the standard DE-9 (DB-9) shell size. The two rows of 9 female sockets carry gold-plated contacts rated 2.2 A per circuit, suited for signal-level duty on RS-232, RS-422, or general-purpose parallel interfaces.
The 0.371" (9.43 mm) backset spacing sets the distance from the PCB edge to the mounting flange face — this dimension governs how far the connector protrudes past the board edge and whether a standard D-Sub hood will clear the enclosure wall. The right-angle through-hole footprint requires a cutout or slot in the PCB for the shell body, not just drilled holes. The steel shell with tin plating provides EMI shielding continuity to the chassis ground when the mating plug's shell contacts it.
Mating Half and Cross-Reference
This receptacle mates with a standard DE-9 (DB-9) D-Sub plug — the male counterpart with 9 pins in the same shell size. The AMPLIMITE HD-20 series includes the matching plug (e.g., TE 5-1393481-5 or similar 9-position male connectors in the same series). No official cross-reference to another brand is on record; the DE-9 shell size is an industry-standard interface, so a plug from any manufacturer with the same shell layout and 9 positions will physically mate, though the board lock and flange features may differ.
