Right-Angle D-Sub for Dense I/O Panels
The TE Connectivity AMPLIMITE.050 III 5787082-7 is a 68-position D-sub receptacle designed for right-angle, board-edge mounting. It uses the 0.050-inch pitch x 0.100-inch row-to-row layout, which is tighter than the standard 0.108-inch D-sub pitch — this drives a specific PCB footprint and requires a mating plug with the same 0.050-inch pitch. The connector is shielded with a steel, nickel-plated shell and includes board locks for mechanical retention during soldering and in-service vibration.
What the 0.050-Inch Pitch and 68 Positions Mean for Your Board
The 0.050-inch pitch is the critical dimension for footprint layout — it is roughly half the pitch of a standard D-sub, so the PCB routing density is higher and the mating plug must be from the same AMPLIMITE.050 III series. The 68 positions in a 2-row arrangement fill a shell size that is specific to this pitch family; a standard D-sub shell will not fit. The through-hole tails provide a stronger solder joint than SMT for a connector this size, and the board locks prevent the connector from lifting during wave solder or under cable strain.
Shielded Construction and Signal Integrity
The steel shell with nickel plating provides EMI shielding for the signal contacts — important for dense digital or low-level analog signals in an electrically noisy enclosure. The shell includes a flange with 2-56 threaded inserts and latchblocks for secure mating with the corresponding plug.
