Eaton 85100AC1832PW50 Receptacle - SI Qualified
Part Number: 85100AC1832PW50
Quick Summary
The Eaton 85100AC1832PW50 is a MIL-DTL-26482 SI qualified square flange receptacle designed for high-density aerospace and industrial connectors. Engineers often struggle with reliable mating under vibration, crowded enclosures, and corrosive environments that complicate maintenance. This solution combines an aluminium shell, cadmium plating, and a straight backshell to deliver lightweight, corrosion-resistant performance without sacrificing strength. The 32-contact layout supports dense harnessing while remaining compatible with Souriau 851-series components, reducing custom fabrication and procurement risk. By standardizing on a robust MIL-grade receptacle, teams can simplify supplier management, streamline assembly, and improve uptime in mission-critical systems. Its 1/3-bayonet coupling and solder-cup contacts provide reliable mating in tight spaces.

MIL-DTL-26482 SI qualified design ensures signal integrity under vibration and temperature cycling, reducing intermittent electrical faults in mission-critical assemblies. By using a proven Souriau 851-series platform, the 85100AC1832PW50 provides a validated mating interface with predictable performance across spares and replacement cycles. With a 32-contact layout, this square flange receptacle enables high-density terminations in compact enclosures, improving harness routing and reducing panel cutouts. Aluminium shell keeps weight down while cadmium plating delivers corrosion resistance in harsh environments common to aerospace and heavy equipment. Backshell adaptor with straight orientation simplifies installation in tight spaces and supports straightforward field replacement without rework. Solder Cup contacts with a 1/3 bayonet coupling provide reliable, vibration-tolerant connections; the 32 potential cavities enable full-channel layouts and easier lead routing. Delivered with connector option simplifies procurement and compatibility with the 851-series family reduces engineering risk and speeds integration into existing systems. In practice, this receptacle supports faster assembly, lower total cost of ownership, and easier spares management in mixed-vendor environments.
