50-Position Shielded D-Sub Receptacle for Ribbon Cable
The TE Connectivity 5749699-5 is a 50-position D-subminiature receptacle from the AMPLIMITE.050 III series, terminated via IDC to standard 0.050-inch pitch ribbon cable. It's a free-hanging (in-line) female connector with a shielded steel shell, nickel-plated, and gold-plated phosphor bronze contacts rated for signal-level current at 1 A per circuit and 30 V. The 2-row layout with 0.050-inch pitch and 0.100-inch row spacing matches the standard D-subminiature footprint for ribbon cable assemblies.
IDC Termination and Ribbon Cable Compatibility
This receptacle uses insulation displacement contacts (IDC) for mass-termination to standard 0.050-inch pitch ribbon cable. The gold-plated phosphor bronze contacts wipe through the insulation on termination, making gas-tight connections without stripping or soldering.
Shielded Construction for EMI Control
The steel shell with nickel plating provides EMI shielding, reducing radiated emissions and susceptibility in signal cable runs. This matters in industrial or telecom environments where cable bundles carry sensitive data near noise sources. The shell also gives mechanical robustness to the D-sub interface, and the nickel finish resists corrosion.
