Eaton 85100E2039PZ50 Receptacle - MIL-DTL-26482 SI Qualified
Part Number: 85100E2039PZ50
Quick Summary
Eaton 85100E2039PZ50 Receptacle provides rugged MIL-DTL-26482 connectivity for aerospace and defense harnesses. A common pain point is securing reliable mating while maintaining compact panel space and environmental protection. This connector meets MIL-DTL-26482 SI qualification and REACH compliance, with a cadmium-plated aluminium shell and backnut for secure mounting. In practice, engineers value the 39 contacts, 1/3 Bayonet coupling, and Z orientation for fast field service and predictable performance. Designed for 39-pin configurations, it aligns with standard chassis and harness layouts, simplifying supplier qualification. Its square flange and backnut enable straightforward panel installation even in tight spaces.
