Eaton 85100E1626P50 Connector - MIL-DTL-26482 SI
Part Number: 85100E1626P50
Quick Summary
The Eaton 85100E1626P50 Connector is a MIL-DTL-26482 SI qualified connector designed for rugged industrial and aerospace harness applications. Engineers often contend with corrosion, backnut stability, and contact reliability in harsh environments, making a robust, field-ready option essential. This 26-contact receptacle combines cadmium plating and an aluminium shell to balance weight and durability, with a square flange mounting interface and a backnut for secure panel installation. Its N-oriented connector and 1/3 Bayonet coupling simplify mating in tight spaces, while pre-loaded, solder-cup contacts speed assembly. With REACH compliance noted, these features translate to lower maintenance, longer service intervals, and predictable interchangeability with other 851-series components in demanding automation and avionics applications.

The 85100E1626P50 provides a high-density 26-contact interface with a 1/3 Bayonet coupling and solder cup contacts. This high-density arrangement supports complex signal and power runs in a compact space, delivering reliable mating and faster field assembly—critical in avionics and rugged automation. In practical terms, this reduces wiring errors and minimizes downtime during maintenance windows. Cadmium plating paired with an aluminium shell delivers corrosion resistance without excessive weight. The shell size 16 and square flange receptacle geometry offer a rigid mounting footprint, enabling consistent torque control on panels and reducing misalignment during assembly. Backnut mounting with straight backshell and N orientation simplifies panel integration in tight enclosures, while the delivered with connector option ensures no loose components. The operating range of -40 °C to 125 °C supports performance in extreme environments, and the 26-contact layout remains interchangeable with other 851-series connectors to optimize spares strategies and reduce lifecycle costs. Compatibility with the 851-series ecosystem enables rapid replacement and component standardization across multiple programs.

FAQs
Yes. The 85100E1626P50 uses a 1/3 Bayonet coupling and backnut mounting compatible with the Souriau 851-series backnut assemblies. It features a square flange receptacle and N orientation for straightforward panel integration, ensuring secure mating and repeatable assembly in tight or vibration-prone installations.
The connector provides 26 solder-cup contacts in a 26-position layout, with an aluminium shell and cadmium plating. It supports operation from -40 °C to 125 °C and is REACH compliant, offering reliable performance under extreme temperatures and environmental regulations typical in aerospace and industrial environments.
Aerospace, defense, and rugged industrial automation benefit most. The MIL-DTL-26482 SI qualification, high-contact density, vibration resistance, and compact square flange form factor make it ideal for aircraft harnesses, military equipment, and heavy-duty control panels where reliability and interchangeability are paramount.
This product is MIL-DTL-26482 SI qualified and REACH compliant, addressing critical regulatory and environmental requirements for aerospace and industrial programs. Cadmium plating is specified, which is common in high-reliability connectors but should be considered within your material compliance strategy.
Pre-loaded solder-cup contacts, backnut mounting, and a robust aluminium shell reduce installation time and field wiring errors, increasing uptime. The high-density 26-contact layout enables fewer connectors for complex systems, lowering spare parts requirements and lifecycle costs while improving interchangeability within the 851-series family.
