Eaton 85100AC168SZ50 Square Receptacle - MIL-DTL-26482 SI
Part Number: 85100AC168SZ50
Quick Summary
Eaton 85100AC168SZ50 is a square flange receptacle designed for MIL-DTL-26482 SI qualified connections in harsh aerospace and industrial assemblies. In tight installations where vibration and corrosion risk threaten signal integrity, easy mating and reliable sealing are essential. This design supports MIL-DTL-26482 SI qualification, REACH environmental compliance, and a cadmium-plated aluminium shell that withstands challenging conditions. With a compact 51 mm length and a 31.3 mm square footprint, it keeps harnesses tidy in restricted spaces. The straight backshell with Z orientation and 1/3 bayonet coupling streamline installation, while eight solder-cup contacts deliver robust, quick-connect performance for multi-conductor runs in mixed-signal systems.

The eight-contact configuration provides multi-circuit capability within a compact envelope, reducing wiring harness density and simplifying routing. This lowers assembly time and the risk of miswiring in complex systems, making it well-suited for aerospace harnesses and rugged industrial controls. Cadmium plating on an aluminium shell offers improved corrosion resistance in challenging environments, extending service life and lowering maintenance costs for fielded equipment. The square flange receptacle form factor with a size 16 shell delivers a balance of strength and weight, supporting lightweight, high-reliability interconnects in mobile platforms and portable machinery. A straight backshell adaptor with Z orientation and 1/3 bayonet coupling enables faster mating, reduces technician fatigue, and improves repeatability during fitting in confined spaces. Solder cup contacts provide robust, soldered terminations that are forgiving in rework scenarios and support reliable high-current or mixed-signal connections. With eight cavities and a defined footprint, this connector facilitates standardized harness design and streamlined procurement across projects. The assembly is compatible with the Eaton Souriau 851 series ecosystem, which helps integrators consolidate parts and simplify spares management while maintaining performance under -40 °C to 125 °C.

FAQs
This receptacle uses a straight backshell with Z orientation and a 1/3 bayonet coupling for fast, repeatable mating in tight spaces. It is delivered as a connector-equipped unit, with eight solder cup contacts ready for field assembly. Ensure proper alignment with the mating plug and verify connector orientation labels before engagement to avoid misdetection or misalignment during maintenance.
MIL-DTL-26482 SI qualification guarantees a robust interconnect design that withstands vibration, thermal cycling, and mechanical shock typical of aerospace and military applications. Combined with cadmium-plated aluminium housing and REACH compliance, the connector delivers consistent contact integrity and corrosion resistance across a wide operating temperature range (-40 to 125 °C).
Yes. With eight contacts, a compact 51 mm length, and a square 31.3 mm footprint, the receptacle fits multi-circuit harnesses in space-constrained aerospace and rugged industrial environments. The aluminium shell size 16, cadmium finish, and solder cup contacts support reliable, high-integrity connections in mixed-signal systems while remaining compatible with the Souriau 851 series.
Key verifications include MIL-DTL-26482 SI qualification for high-reliability interconnects and REACH compliance for environmental safety. The cadmium plating, aluminium shell, and operating temperature range (-40 to 125 °C) are additional specifications to confirm with procurement to ensure regulatory alignment and lifecycle suitability.
The eight-contact configuration reduces wiring complexity and installation time, while the sturdy cadmium-plated aluminium shell improves longevity in harsh environments. Quick-mating with 1/3 bayonet coupling lowers field service time, and solder cup terminations offer reliable repair options, contributing to lower maintenance costs and higher system uptime over the product lifecycle.
