26-Position Shielded D-Sub for Signal-Level Board-Edge Interconnects
The TE AMPLIMITE.050 III 5787082-2 is a 26-position D-sub receptacle with female sockets arranged in two rows. It uses a 0.050-inch pitch with a 0.100-inch row-to-row spacing — the compact layout typical of the.050 III series, designed for high-density signal interconnects where board real estate is tight. The gold contact finish on phosphor bronze terminals provides reliable mating over repeated cycles, a typical requirement for field-serviceable connections. The steel shell with nickel plating and the board lock feature add mechanical retention and EMC shielding, keeping the connection stable in electrically noisy environments. This is a connector you'd specify for a test rack, a PLC I/O card, or a medical device backplane — anywhere a shielded, right-angle D-sub with a known footprint is needed.
Board Lock and Shielded Shell — What They Mean for Assembly
During wave or selective soldering, they hold the connector in place against the surface tension of the solder, preventing skew. After soldering, they provide a mechanical anchor that resists shear forces from the mating cable — important for a right-angle connector that sees levering stress when the plug is inserted or removed. The shielded steel shell with nickel finish serves two purposes: it contains radiated emissions from the signals inside the connector, and it bleeds common-mode noise to chassis ground when the mating plug's shell contacts it.
