50-Position Shielded D-Sub for Dense Signal I/O
The TE 5787190-5 is a 50-position D-sub receptacle from the AMPLIMITE.050 III series, designed for high-density signal interconnect in shielded enclosures. It uses a 0.050-inch pitch with 0.100-inch row spacing, packing 50 gold-plated female contacts into a right-angle through-hole package that mounts at the board edge. Typical applications include industrial control panels, telecom backplanes, and test equipment where a compact, shielded D-sub interface is needed for parallel signal paths.
Right-Angle Board-Edge Fit
The 0.146-inch (3.71 mm) backset spacing positions the shell face a fixed distance from the board edge, which matters when the mating D-sub plug has a specific panel cutout or bracket location. The through-hole termination gives a robust solder joint that handles the mechanical leverage from the cable assembly better than an SMT version would.
Gold Contacts and Shielding for Signal Integrity
Gold-plated phosphor bronze contacts rated at 1 A per circuit and 30 V — this is a signal connector, not a power interconnect. The shielded steel shell with nickel plating and the housing/shell flange with 2-56 threaded inserts and latchblocks gives a positive ground path through the enclosure, bleeding shield currents before they reach the signal pins.
Mating and Harness Fit
This receptacle mates with a standard AMPLIMITE.050 III D-sub plug (male pin connector) in the same series, using the 2-56 threaded inserts and latchblocks for secure panel-mount or cable-to-board connection. The 50-position count and 0.050-inch pitch are specific to the series — the mating half must match both the position count and the shell layout. The solder termination means the connector is soldered directly to the PCB; the cable-side plug uses crimp or solder-cup terminals depending on the variant.
