50-Position Shrouded Header for Board-to-Cable Interconnects
The latch lock/eject hooks provide positive retention against vibration and a mechanical lever for unmating when the connector pair is packed tightly on the board edge.
The base product number is 5499206; variations in plating or packaging carry different dash numbers. No official successor or form-fit-function cross is listed, so the 3-5499206-0 is the direct part for this pinout and finish.
Keying Slot and Mounting Flange for Alignment
A keying slot in the shroud prevents mismating with non-keyed receptacles, and the mounting flange provides an additional mechanical anchor to the PCB — useful when the cable harness exerts shear force on the header during routing or vibration.
