The shielded shell with board locks keeps the ground path continuous and the connector anchored against vibration, which matters when this sits near a noisy backplane or in a rack-mounted chassis where EMI bleed between ports has to stay below the system threshold.
Position Count Comparison with the 36-Position Sibling
The 5787973-1 is the same CHAMP.031 receptacle in the same right-angle, shielded, board-lock format, but with 36 positions instead of 50. Both carry 30.0µin gold plating and the M2.6 flange feature — the only decision variable is whether your BOM calls for 36 or 50 signal lines. If the circuit count fits, the 36-position version is a drop-in swap on the same footprint class; the 50-position version simply occupies more board edge for the extra 14 contacts.
Mating and Mounting Details
Panel-mount flanges with M2.6 hardware secure it to the chassis cutout before soldering, which takes the insertion and extraction stress off the solder joints. The board locks hold the part flat during wave solder. Mates with the matching CHAMP.031 plug — the outer shroud contacts are designed for blind-mating in panel-dress applications where the cable assembly is routed behind a bulkhead.
