Eaton 85100E1412P50 Receptacle - MIL-DTL-26482 SI qualified
Part Number: 85100E1412P50
Quick Summary
Eaton Souriau 851 series MIL-DTL-26482 SI qualified connectors provide rugged square flange receptacles for harsh industrial environments. Engineers often struggle with reliable mating in tight panels and corrosion-prone finishes under temperature swings. MIL-DTL-26482 SI qualification, REACH compliance, and operation from -40 to 125 °C support both aerospace and heavy industry designs. With cadmium plating, a backnut backshell, and a 12-position, 1/3 bayonet layout, it streamlines installation and reduces field maintenance. This combination enables faster assembly, improved long-term reliability, and lower lifecycle costs for critical electrical harnesses.

FAQs
For reliable installation, verify connector orientation (N), align the 12-position layout with the mating plug, and secure the backnut to ensure a tight seal. Use the cadmium-plated contact surfaces and solder cup contacts carefully, avoiding excessive torque on the 1/3 bayonet coupling. Refer to the C05851A drawing for precise assembly geometry and clearance envelopes.
Key specs include 12 contacts in a 12-position layout, 1/3 bayonet coupling, cadmium plating, aluminium shell size 14, and a weight of 19.5 g. Overall dimensions are approximately 32.7 mm length, 28.9 mm height, and 28.9 mm width. Operational temperature ranges from -40 °C to 125 °C, with backnut backshell and straight orientation.
Yes. The MIL-DTL-26482 SI qualification, square flange receptacle format, and 12-contact density make it ideal for aerospace control panels, rugged industrial automation, and mobile/defense equipment. The design supports reliable sealing, robust mating, and ease of integration with backnut backshell assemblies, which are common in mission-critical harnesses.
The connector is MIL-DTL-26482 SI qualified and REACH compliant, ensuring regulatory alignment for global programs. Cadmium plating provides corrosion protection, though cadmium processes should be managed per environmental guidelines. The device is built with an aluminium shell for weight savings and durability in exposed or harsh environments.
The 851 series reduces maintenance cycles through robust MIL-spec construction, corrosion resistance, and reliable solder cup contacts. The backnut backshell and quick 1/3 bayonet connection speed up installation and field servicing, lowering labor costs and downtime while improving overall equipment reliability and return on investment.
