The Molex 464369321 is a 16-position right-angle receptacle from the EXTreme Ten60Power 46436 series, designed for high-current backplane and power-distribution applications. Its contact layout splits into 15 signal circuits and 2 power circuits — a hybrid arrangement that routes the main DC rail through the power blades while keeping signal lines on separate pins. The 60 A per circuit rating means each power blade carries bus-level current, sized for a server PSU, battery interconnect, or industrial power bus rather than a signal line. Press-fit termination keeps the assembly solderless, which matters for backplane builds where reflow would stress the board or where rework needs to be field-friendly.
The 60 A per circuit is the headline number — but the contact plating grade is what governs real duty. The voltage rating splits by type: 600 VAC for line power, 250 VDC for battery or DC bus — match the application voltage type, not just the peak number. The -40 to 105 °C operating range covers outdoor telecom cabinets and industrial enclosures without needing a derating curve for ambient heat. UL94 V-0 housing means it's rated for flame retardance inside equipment enclosures.
