4 Circuits, 3.50 mm Pitch — the Glow Wire Compliant Power Plug
The Molex 2169454004 is a 4-circuit, 2-row plug from the Ultra-Fit 216945 series. The glow wire compliance (per IEC 60335-1) means this plug can be specified for appliances and equipment that require a flame-retardant connector in the event of a fault.
The 2-row, 4-circuit layout means the plug mates with a 2-row, 4-circuit Ultra-Fit header (male pin version) on the board. Because it's a plug, the wire harness side is the female half — the header stays on the PCB.
