20-Position Shielded D-Sub Plug for Ribbon Cable
This is the male pin half of a D-sub pair, intended for free-hanging (in-line) cable assemblies where a shielded, low-profile interconnect is needed. The 0.050-inch pitch and 0.100-inch row-to-row spacing define the AMPLIMITE.050 III footprint — finer than the standard 0.108-inch D-sub pitch, which means it mates only with its matching AMPLIMITE.050 III receptacle, not with standard-density D-subs. Key characteristics include a shielded steel shell with tin-nickel plating for EMI suppression, gold-plated phosphor bronze signal contacts rated at 1 A per circuit at 30 V, and a UL94 V-0 thermoplastic housing.
What the 0.050-Inch Pitch and 1 A Rating Mean for the Fit
The 0.050-inch pitch is the defining dimension of the AMPLIMITE.050 III series — it is half the pitch of a standard D-sub (0.108-inch), so the 20 positions fit in a shell roughly the size of a standard 9-position D-sub. The IDC termination is a production-speed advantage — the ribbon cable is pressed onto the contacts in one operation, no individual wire stripping or crimping. The trade-off is that field repair means replacing the entire plug, not a single contact. For harness builders, this plug is the correct choice when the cable assembly is built in volume and the cable is a standard 20-conductor ribbon.
