The TE Connectivity 5787394-7 is a 68-position D-sub receptacle from the AMPLIMITE.050 III series — the high-density variant that packs 68 signal contacts into a shell size that would normally carry half that count at standard 0.108-inch pitch. This is the connector you reach for when a parallel bus, a bank of I/O lines, or a flat-cable signal bundle needs a shielded, screw-locked interconnect on a board edge. The 0.050-inch pitch between contacts and 0.100-inch row spacing let it route through a dense PCB footprint without forcing a larger card-edge connector.
Shielding, Latchblocks, and the Hardware That Holds It Together
This receptacle includes the flange features that matter for field service: housing/shell mounting with 2-56 threaded inserts and latchblocks. The 2-56 screws provide positive mechanical retention against vibration and cable strain — a standard D-sub screwlock pattern that mates with any matching plug equipped with female screwlocks or a slide-lock. The latchblocks add a secondary snap retention that resists accidental unmating during equipment handling. The shielded shell is a steel shell with nickel plating — it grounds through the mounting hardware and the connector interface, bleeding EMI before it reaches the signal contacts. If your application runs high-speed digital or sensitive analog lines near noisy power supplies, the shield is the difference between a clean eye diagram and a crosstalk problem. The backset spacing of 0.146 inches (3.71 mm) sets the distance from the board edge to the mounting face — check your enclosure clearance before layout.
