Frequently Asked Questions
What standards does this 7-meter Molex 4.2mm power cord comply with?
The cable assembly is manufactured strictly compliant with IPC/WHMA-A-620E workmanship standards, tested to UL 486A terminal pull force requirements, and 100% factory inspected for open circuits, shorts, and wiring continuity.
Can the cable length or connector housing be customized?
Yes. While standard production is 7000mm with Molex 39012061/39012060 6-pin housings and dual-wall glue shrink tube strain relief, custom wire gauges, lengths, pinout configurations, and waterproof overmolding are available on demand.
Overview and Application Notes
Overview: High-Temperature 6-Pin Molex Power Extension Assembly
The Molex 4.2mm 6-Pin High Temp Power Cord Assembly (A002-00048-01) is an industrial-grade power delivery interconnect engineered specifically for thermal-stress environments, high-temperature ventilation, industrial heating systems, and flue exhaust equipment. Featuring a 7-meter (7000 ± 210 mm) 3-core high-flex power cable rated for 105°C and 300V, this assembly bridges high-performance board-to-cable or cable-to-cable power lines with panel-mount retention.
Built with genuine-equivalent Molex Mini-Fit Jr. 4.2mm pitch housings (39012061 plug and 39012060 receptacle), the assembly provides positive-locking engagement and dual-wall adhesive heat shrink tubing strain relief to prevent wire pull-out, moisture ingress, and vibration fatigue.
