Eaton 85100E1210PY50 Receptacle - MIL-DTL-26482 SI
Part Number: 85100E1210PY50
Quick Summary
Eaton 85100E1210PY50 is a square flange receptacle for MIL-DTL-26482 SI qualified assemblies used in harsh aerospace and industrial environments. In-field assemblies risk misalignment and unreliable solder contacts, leading to downtime and costly rework. This connector family meets MIL-DTL-26482 SI qualification, supports REACH compliance, and is designed for high-temperature operation. Its backnut design, cadmium plating, and solder cup contacts streamline installation, reduce rework, and improve reliability in critical applications. For design engineers, the 851 series offers predictable mating, panel mounting compatibility, and a robust temperature range. Procurement teams appreciate the conformance to established Souriau/Suaire standards, aiding spares rationalization and serviceability across global projects.

MIL-DTL-26482 SI qualification ensures rugged, avionics-grade performance for demanding environments, while the backnut backshell and cadmium plating provide corrosion resistance and a secure, field-reliable seal. The 85100E1210PY50 delivers 10 solder cup contacts in a compact aluminium shell with a straight backshell and a 1/3 bayonet coupling for fast, repeatable mating. This combination reduces assembly time, minimizes contact resistance drift under vibration, and enhances EMI integrity in control panels and sensor arrays. The Y orientation and delivered-with-connector option streamline harness routing and assembly workflows, supporting rapid installation and easier spares management. With a -40 to 125 °C operating window, it withstands temperature extremes common in aerospace, military, and heavy equipment applications. Long-term, the solution lowers maintenance costs by improving reliability and minimizing unexpected field failures.

FAQs
To install, align the receptacle with the panel cutout, mate the male solder contacts, and secure the backnut from the backside. The unit uses a 1/3 bayonet coupling and Y orientation for correct alignment; ensure the shell is aluminium and the cadmium-plated contacts are clean before mating. After connection, verify contact integrity and torque specs per Souriau/Eaton guidelines.
Key specifications include 10 contacts in a 10-cavity arrangement, pin male contacts, 1/3 bayonet coupling, straight backshell with backnut, cadmium plating, aluminium shell, and an operating temperature range from -40 °C to 125 °C. It supports a Y orientation and is delivered with connector hardware for rapid integration into panels.
Yes. The part is MIL-DTL-26482 SI qualified, designed for high vibration and wide temperature environments typical of aerospace and defense. Its aluminium backnut shell and robust plating provide durability in demanding aircraft, ground-support equipment, and defense systems, while REACH compliance supports regulatory expectations in modern programs.
Certifications include MIL-DTL-26482 SI qualification and REACH environmental compliance. The cadmium plating offers corrosion resistance, which may be subject to program-specific cadmium restrictions; ensure your project’s regulatory requirements are accounted for when selecting this connector within your supply chain.
The 85100E1210PY50 reduces downtime through reliable mating and a secure, vibration-resistant connection, lowering field rework costs. Its durable aluminium shell and wide operating temperature range extend service life in harsh environments, enabling lower replacement frequency and simpler spares management across programs. Overall, this translates to faster maintenance cycles and lower total cost of ownership.
