26-Position High-Density D-Sub Plug for Right-Angle PCB Mounting
The TE Connectivity AMPLIMITE HD-22 2311776-1 is a 26-position D-Sub high-density plug with male pins arranged in 3 rows, terminated through-hole and soldered at a right angle to the PCB. This shell size 2 (DA, A) high-density layout packs 26 signal contacts into the footprint of a standard 15-pin D-Sub, saving board edge real estate.
Board Locks and Grounding Indents Secure the Connection
Two features on this plug address the mechanical and electrical realities of a right-angle D-Sub on a PCB. This matters in noisy industrial or telecom environments where shield continuity reduces radiated emissions.
This plug mates with a standard D-Sub high-density receptacle of the same shell size (DA, A layout) — typically the TE AMPLIMITE HD-22 receptacle with 26 female contacts. The flange uses 4-40 threaded inserts for jackscrew locking, which is the standard D-Sub fastening pattern. On the PCB side, the 26 through-hole solder tails are arranged in three rows at the high-density pitch; the right-angle bend means the tails emerge perpendicular to the connector body.
No official second-source cross-reference is listed, but the AMPLIMITE HD-22 series includes functionally similar 26-position plugs such as 8-1437045-3 (Bulk package, Active) and 3-1393480-8 (Box package, Active) — verify the specific packaging and any minor dimensional differences in the product drawings before substituting.
