28-Position Shielded D-Sub Plug for Ribbon Cable
The TE Connectivity AMPLIMITE.050 III 5749621-3 is a 28-position D-sub plug with male pins, designed for mass-termination to ribbon cable via IDC contacts. The dual-row layout uses the standard 0.050-inch pitch with 0.100-inch row-to-row spacing — the footprint for high-density D-sub signal interconnects.
The 1 A per-contact rating at 30 V places this connector firmly in the signal-density class — think parallel data buses, control lines, or low-power I/O, not power distribution. The 28 positions pack into a shell size that is physically smaller than a standard DB-25, so the current limit reflects the contact density and the IDC termination's current-carrying capacity.
Shielding and Environmental Ratings
The steel shell with tin-nickel finish is the EMI shield — it grounds through the D-sub shell to the mating receptacle's shield, containing radiated emissions from the ribbon cable.
This is the cable-end plug — free-hanging (in-line) mount, mates with a standard AMPLIMITE.050 III receptacle (solder-cup or PCB-mount). The IDC termination accepts ribbon cable and terminates all 28 conductors simultaneously when pressed with a hand tool or press.
