15-Position Right-Angle D-Sub Plug with Board Locks
It uses the standard DA shell size (EIA layout 2), which is the common footprint for 15-pin D-subs. Gold flash contacts handle signal-level duty at 6 A per contact, while the steel shell with tin plating provides EMI shielding and mates with the standard D-sub receptacle frame.
Board Lock and Grounding Features
The ground strap and grounding indents on the shell provide a low-impedance path from the connector shell to the board ground plane, bleeding shield currents before they reach the signal pins. These features make the 5747841-3 a better fit for production assemblies where mechanical retention and EMI control are required, compared to a basic solder-cup D-sub that relies on the solder joints alone.
6 A per Contact — Signal Duty, Not Bulk Power
For loads above a few amps per circuit, derate per the product drawing.
The flange uses 4-40 threaded inserts (housing/shell type) for screw-lock retention — the mating receptacle must have the corresponding female screwlock or through-hole for a 4-40 jack-screw.
