Eaton 85100AC2025SW50 Receptacle - MIL-DTL-26482 SI
Part Number: 85100AC2025SW50
Quick Summary
The Eaton 85100AC2025SW50 is a square flange MIL-DTL-26482 receptacle designed for rugged, high‑reliability interconnections in aerospace, defense, and industrial automation. Engineers often struggle with corrosion, misalignment, and contact wear in harsh environments, leading to reliability risk and costly downtime. This design emphasizes MIL-DTL-26482 SI qualification and REACH compliance to help teams meet stringent regulatory and performance targets. The combination of a cadmium-plated aluminium shell, 25-position layout, and quick mating with 1/3 bayonet coupling delivers predictable performance, easier field maintenance, and scalable harnessing for growing automation needs. It also supports compatible Souriau 851-series connectors for fast integration. This makes procurement simpler and installation more predictable across plant sites.

FAQs
Installation starts with confirming the 25-position layout and the W orientation for correct alignment. Use the 1/3 bayonet coupling for a secure, vibration-resistant mate, and attach the straight backshell adaptor as required. Ensure the cadmium-plated aluminium shell is clean and free of contaminants before mating to maintain low contact resistance and reliable signal integrity over time.
The connector supports a wide operating range from -40 °C to 125 °C, suitable for harsh environments. It is REACH compliant, and utilizes cadmium plating on an aluminium shell to afford corrosion resistance. These features help ensure dependable performance in aerospace, defense, and industrial automation applications where temperature extremes and exposure are common.
Yes. The 85100AC2025SW50 is designed to be compatible with Souriau 851-series harnesses and other MIL-DTL-26482 components. The W orientation and 25-position layout support consistent mating with existing connectors in Souriau lineups, enabling streamlined procurement and integration across multi-vendor assemblies.
This receptacle is MIL-DTL-26482 SI qualified, providing a robust reliability framework for demanding applications. It also complies with REACH environmental standards. In addition, the cadmium-plated aluminium shell offers corrosion protection suitable for challenging environments encountered in aerospace and industrial settings.
The cadmium plating and aluminium shell deliver strong corrosion resistance, reducing replacement frequency and downtime. The 25-position solder-cup contacts and quick 1/3 bayonet mating shorten maintenance windows and field servicing. Over time, this translates to lower labor costs, higher machine uptime, and predictable lifecycle costs in automation and production environments.
