Eaton 85100A2041SX50 Receptacle - MIL-DTL-26482 SI qualified
Part Number: 85100A2041SX50
Quick Summary
The Eaton 85100A2041SX50 receptacle delivers rugged MIL-DTL-26482 SI qualified performance for harsh aerospace and industrial assemblies. Engineers frequently face moisture ingress, misalignment of contacts, and space constraints that slow integration. MIL-DTL-26482 SI qualification and REACH environmental compliance provide robust reliability, while cadmium plating enhances contact resilience. With an aluminium shell, straight backshell adaptor, and a 1/3 bayonet coupling, installation is straightforward and repeatable. This combination supports faster sourcing, predictable performance, and lower lifecycle costs for aerospace, defense, and high-demand industrial environments. Customers also benefit from clear specifications, easier procurement, and compatibility with Souriau 851 series components for scalable systems in the field.

MIL-DTL-26482 SI qualification provides a high-reliability baseline for mating in vibration and temperature cycles, reducing field failures and warranty costs. The 41 contact positions with solder cup contacts enable high-density terminations in compact enclosures, improving signal and power routing for aerospace and industrial automation projects. Cadmium plating offers corrosion resistance in demanding environments, lowering maintenance frequency and extending lifecycle readiness for exterior or humid installations. The aluminium shell and 20 shell size deliver a lightweight yet durable housing that helps achieve tighter panel fits and easier handling during assembly and servicing. A straight backshell adaptor and 1/3 bayonet coupling support fast, repeatable mating/demating, minimizing downtime during system updates or field upgrades. Delivered with connector and X-axis orientation compatibility streamline procurement and system integration, promoting scalable sourcing across Souriau 851 series components for mixed-fleet deployments. In practice, engineers gain confidence in interchangeability and long-term support, addressing common objections about rugged performance and maintenance cost while enabling more predictable project timelines.

FAQs
Yes. The 85100A2041SX50 is a MIL-DTL-26482 SI qualified square flange receptacle designed to mate with MIL-DTL-26482 interfaces. It uses a 1/3 bayonet coupling for secure mating and a straight backshell adaptor, enabling quick, repeatable installation in harsh environments without special tools.
The receptacle is a 41-position, socket (female) contact, with solder cup termination. It delivers 41 cavities in a compact aluminium shell (shell size 20), offering high-density connectivity suitable for multi-channel signal and power lines.
Yes. With MIL-DTL-26482 SI qualification and REACH compliance, along with high-density contact layouts and rugged cadmium plating, this receptacle is well-suited for aerospace, defense, and demanding industrial automation environments requiring reliable, long-term performance.
Key certifications include MIL-DTL-26482 SI qualification. Environmental compliance is supported by REACH, and the CADMIUM plating specification provides corrosion resistance for challenging environments while remaining aligned with regulatory considerations.
Cadmium plating offers superior contact durability and corrosion resistance, reducing maintenance frequency in harsh environments. The aluminium shell keeps weight low and supports compact installations. Plan for periodic inspection of mating interfaces and ensure compatibility with standard Souriau 851 series components to maintain interchangeability and simplify future upgrades.
