Right-angle header for board-edge signal routing
The 1-1939638-0 is a 40-position, dual-row header from TE's Dynamic D-1100 series, pitched at 2.00mm between contacts and 3.30mm between rows — a spacing that keeps PCB routing dense without crowding traces under the component. It mounts through-hole and exits right-angle, so the mated cable runs parallel to the board surface — a common fit in control cabinets where the header sits near the board edge and the harness tucks against the enclosure wall. The shroud wraps all four sides of the contact array, and a detent lock on the mating face holds the plug in place against vibration; the board lock anchors the header through reflow and into service.
