DB25 Right-Angle Plug for Board-Edge Signal Interconnects
The TE Connectivity AMPLIMITE HD-20 5747842-4 is a 25-position D-sub plug in the standard DB25 shell layout (3, DB, B). It terminates 25 signal contacts in two rows, each rated 6 A at 125 V — enough headroom for RS-232, parallel data, or low-power I/O on a single harness. The right-angle solder tails let you mount this plug flush to the board edge, saving depth inside the enclosure. Gold plating on the brass contacts resists corrosion and holds up to repeated mate/unmate cycles in field-service or test-rack duty.
Board Lock and Grounding Features for Reliable Assembly
Three features on this plug make it a solid choice for builds that see vibration or need clean shield continuity. The flange uses 4-40 threaded inserts for the mating jackscrews — the same standard as every DB25 backshell on the market. If you are rebuilding a cable loom, any metal DB25 backshell with 4-40 screws will fit this plug.
