Eaton 85100A1418SW50 Receptacle - MIL-DTL-26482 SI Qualified
Part Number: 85100A1418SW50
Quick Summary
Eaton Souriau 851 series MIL-DTL-26482 SI qualified connectors provide robust interconnects for aerospace and industrial equipment. In demanding environments, compatibility gaps and slow terminations drive downtime and repair costs. This receptacle leverages cadmium-plated aluminium construction, a wide -40 °C to 125 °C operating range, and MIL-DTL-26482 SI qualification to support mission-critical performance. With 18 solder cup contacts, a straight backshell adaptor, and a 1/3 bayonet coupling, installation is efficient and reliable, while the square flange receptacle ensures secure panel mounting. Translated into maintenance and total cost of ownership, this design reduces field failures and supports long-term availability in automation and avionics systems.

MIL-DTL-26482 SI qualification provides MIL-grade compatibility and traceable performance across demanding platforms. Business impact: customers can rely on interchangeable 851 series components without redesign, reducing procurement complexity and spare-part inventory. Application: aerospace, defense, and high-reliability industrial equipment that must meet stringent interchangeability standards. 18 solder cup contacts enable compact, robust terminations on control panels and instrumentation, improving signal integrity and speeding assembly in production environments. Cadmium plating on an aluminium shell offers corrosion resistance and durability in harsh settings, while the -40 to 125 °C operating range supports reliable operation in extreme climates. The straight backshell adaptor and 1/3 bayonet coupling provide quick, secure mating and easy field servicing, reducing maintenance time and downtime. The square flange receptacle design simplifies panel mounting and alignment, delivering repeatable installation across multiple enclosures and cabinets. Delivered as a ready-to-mate connector, this unit minimizes assembly steps and supports lower installation risk in aerospace, defense, and industrial automation applications.

FAQs
The 85100A1418SW50 is a square flange receptacle designed for panel mounting with a straight backshell adaptor. It supports a 14-shell size with an 18-contact layout and a W orientation, aiding precise alignment and secure mounting on standardized panels in aerospace, defense, and industrial automation environments.
This receptacle delivers 18 solder cup contacts in a single 18-way contact arrangement, with a 1/3 bayonet coupling for quick mating. The aluminium shell is cadmium plated, and the operating temperature range is -40 °C to 125 °C, enabling reliable operation in harsh environments while maintaining signal integrity.
Yes. The product is MIL-DTL-26482 SI qualified, a specification widely used in aerospace, defense, and high-reliability industrial systems. Combined with its robust cadmium-plated aluminium shell and wide temperature range, it is well-suited for mission-critical interconnects and harsh service conditions.
The unit is REACH compliant for environmental considerations and uses cadmium plating as specified, with an aluminium shell for corrosion resistance. These features support regulatory alignment and long-term reliability in global deployments where environmental mandates are enforced.
The 1/3 bayonet coupling enables faster mating/demating, reducing installation and maintenance time. The 18-contact, solder-cup design provides robust terminations with high signal integrity, which lowers field failures and extends service life, improving total cost of ownership for avionics, machinery controls, and other critical automation systems.
