Eaton 85100E128PX50 Receptacle - MIL-DTL-26482 SI qualified
Part Number: 85100E128PX50
Quick Summary
The Eaton 85100E128PX50 Receptacle is a MIL-DTL-26482 SI qualified square flange connector designed for rugged environments and demanding equipment. This high-integrity receptacle provides reliable, sealed electrical mating in aerospace, defense, and industrial automation where vibration, temperature swings, and exposure to contaminants challenge performance. A common pain point is ensuring secure connections that survive repeated mating cycles without contact degradation or wear. The 85100E128PX50 addresses this with a durable aluminium shell, cadmium plating, and a backnut backshell that supports straight mounting and robust alignment. The connector’s eight solder-cup contacts deliver solid electrical contact, while the X orientation and 1/3 bayonet coupling simplify installation and field servicing. This makes it a valuable option for OEMs seeking compliant, long-life interconnects.

FAQs
The 85100E128PX50 uses a square flange receptacle design with a backnut backshell,Straight backshell, and X orientation. It is compatible with common panel cutouts and mounting patterns used with Souriau 851 series, simplifying alignment and reducing the risk of mis mating during installation. Ensure the panel thickness matches your backnut specifications and that mating connectors are oriented for X alignment to maintain proper engagement.
Key specifications include eight solder cup contacts in a MIL-DTL-26482 SI qualified assembly, an operating temperature range of -40 °C to 125 °C, cadmium plating for corrosion resistance, and aluminium shell construction (shell size 12). The straight backnut and 1/3 bayonet coupling provide secure, vibration-resistant mating, suitable for aerospace, defense, and industrial machinery.
Yes. The 85100E128PX50 is designed around MIL-DTL-26482 SI qualification with REACH environmental considerations, making it appropriate for aerospace and industrial automation. Its eight-position, high-density arrangement, compact footprint, and bayonet coupling support reliable performance in vibration-prone environments while meeting stringent regulatory expectations.
This receptacle is MIL-DTL-26482 SI qualified, confirming military specification conformance, and REACH-compliant for environmental safety. It features cadmium plating for corrosion resistance and aluminium shell for lightweight durability, aligning with industry standards for demanding field use.
Delivered with connector and loaded contacts, the 85100E128PX50 streamlines assembly by reducing parts handling and preparation time. The straight backshell and backnut design simplify panel mounting, while the robust bayonet coupling minimizes mating effort and wear. These factors collectively shorten downtime, improve field reliability, and lower lifecycle maintenance costs.
