SDL Plug, 4-Position, 24 AWG — Series 50
The 5-520424-1: The housing is clear and gray polycarbonate (PC), keyed so it only mates with the matching SDL receptacle in the correct orientation — no forcing a misaligned pair.
1.5 A at 30 V — Signal-Level Power Budget
The 30 V ceiling keeps it inside SELV (Safety Extra-Low Voltage) territory for most applications. The 0.855" (21.72 mm) body length fits within a standard hand-held crimp tool jaw; the 24 AWG wire gauge matches the contact barrel diameter, so the crimp pulls the full strand bundle without necking down.
Gold Contacts — Why the Thickness Matters
The 50.0 µ" gold over copper alloy contact finish is not the thin flash you see on low-cost signal headers. For a plug that may be disconnected during field maintenance — SDL jacks in patch panels or equipment racks — that plating grade buys years of reliable contact resistance.
