Eaton 85100E2027P50 Receptacle - MIL-DTL-26482 SI qualified
Part Number: 85100E2027P50
Quick Summary
The Eaton Souriau 85100E2027P50 is a MIL-DTL-26482 SI qualified square flange receptacle for rugged aerospace and industrial use. Engineers frequently wrestle with space limitations, vibration, and corrosion risk in field assemblies. MIL-DTL-26482 SI qualification and REACH-aligned environmental considerations help you meet reliability and regulatory needs. Cadmium plating provides robust corrosion resistance, while the aluminium shell delivers weight savings without sacrificing strength. For project teams and maintenance planners, this delivers faster installations, lower risk of field failures, and a clear total-cost-of-ownership advantage. It is delivered with the connector, simplifying procurement and installation for assembly lines and remote sites. Designed for N orientation and a straight backshell, it supports straightforward integration with standard harnesses.

FAQs
Begin by aligning the receptacle with the mating connector using the N orientation. Slide the backnut to secure the flange and engage the 1/3 bayonet coupling for a confident, vibration-resistant mate. Ensure the solder cup contacts are properly seated and the mating interfaces are clean. Finally, verify workload clearance and torque per standard assembly practices to avoid misalignment.
Confirm 27 contact positions and the 27 cavity count, square flange receptacle configuration, backnut mounting, straight backshell, and 1/3 bayonet coupling. Note the aluminium shell with cadmium plating, 34.5 mm length, 36.9 x 36.9 mm footprint, and weight around 41.9 g. Operating range from -40 °C to 125 °C and REACH environmental considerations are also important.
Yes. The 85100E2027P50 is MIL-DTL-26482 SI qualified, featuring a secure backnut, 1/3 bayonet coupling, and a robust solder cup male contact configuration. Its aluminium shell keeps weight down without compromising strength, while its broad operating temperature range supports both aerospace and industrial robotics, automation equipment, and rugged field deployments.
The connector carries MIL-DTL-26482 SI qualification, which is a key aerospace and defense interconnect standard. It is aligned with REACH environmental considerations, and it uses cadmium plating for corrosion protection. These factors collectively support reliability in harsh environments while meeting regulatory expectations for sensitive applications.
The combination of cadmium plating and aluminium shell provides corrosion resistance and reduced weight, extending service life in challenging environments. The 27-position layout reduces connector sprawl, while the backnut and 1/3 bayonet coupling simplify mating and disconnection, lowering maintenance downtime and improving overall system uptime and ROI in production lines and service fleets.
