Eaton 85100E1418P50 Receptacle - MIL-DTL-26482 SI
Part Number: 85100E1418P50
Quick Summary
The Eaton 85100E1418P50 receptacle delivers rugged MIL-DTL-26482 connectivity for heavy industrial and aerospace assemblies. This connector supports 18 solder-cup contacts in a square flange backnut housing, enabling reliable signal and power transfer in tight spaces. Engineers often struggle with mating alignment and corrosion concerns in harsh environments; this design mitigates those pain points with a cadmium-plated aluminium shell and a straight backshell that simplifies installation. The solution is MIL-DTL-26482 SI qualified and REACH compliant, providing verified performance in demanding applications. By pairing precise manufacturing with field-proven materials, it reduces maintenance cycles and boosts uptime. Secondary benefits include compatibility with standard Souriau 851 series interfaces and rapid field replacements.

With 18 solder cup contacts, the 85100E1418P50 delivers robust signal and power paths in compact harness geometries. This arrangement reduces contact resistance variability and stabilizes high-current connections under vibration, delivering consistent performance in demanding environments. It is ideal for avionics, defense, and industrial automation where space is tight and reliability matters. 1/3 Bayonet coupling enables quick mating and positive retention without tools. The fast coupling shortens assembly and maintenance cycles while maintaining EMI integrity through the straight backshell and backnut design. This is particularly beneficial in field service, where time-to-connect is critical and rework costs are high. Aluminium shell with a size 14, cadmium plating provides a strong balance of light weight and corrosion resistance. The square flange receptacle format offers predictable alignment on mating panels, simplifying integration with existing Souriau 851-series interfaces and improving repeatability across production lines. Operating temperature range -40 to 125 °C ensures reliability in extreme environments, from cold aerospace to hot industrial machinery. REACH compliance further supports regulatory requirements in many regions, reducing compliance risk for assembly teams and end-users. Delivery with connector ensures immediate usability in controlled manufacturing processes; the male pin contacts and backnut orientation 'N' align with standard mating ergonomics, streamlining installation and reducing errors.
