MIL-DTL-26482 SI qualification ensures a resilient mating interface under vibration and temperature extremes, reducing field failures and warranty costs. This reliability matters in aerospace, defense, and heavy industrial equipment where downtime is costly and safety margins are tight. Cadmium plating on an aluminium shell provides robust corrosion protection without excessive weight, supporting longer service intervals and higher duty cycles in exposed environments. The 15 solder-cup female contacts paired with a 1/3 bayonet coupling offer secure electrical connections and straightforward assembly, while the backnut backshell improves field maintenance and simplifies panel mounting. Delivered with connector and oriented for Y configuration, the design supports common harness layouts and enables faster installation in crowded control cabinets. With a compact shell size 14 and 32.7 mm by 28.9 mm footprint, designers can maximize channel density without compromising signal integrity. REACH compliance and MIL-DTL-26482 SI qualification help align procurement with regulatory and sustainability goals, reducing total cost of ownership over service life.

FAQs
The 85100E1415SY50 is a square flange receptacle with a backnut, designed for straightforward panel mounting in tight spaces. It uses a 1/3 bayonet coupling and Y orientation, delivering reliable mating in vibration-prone environments. Delivered with connector and backnut, it supports rapid installation in control cabinets and rack-mounted assemblies while maintaining 15-position electrical performance.
The receptacle operates from -40 °C to 125 °C, covering wide ambient temperature ranges typical in aerospace and industrial environments. It is designed with cadmium plating on an aluminium shell and is REACH compliant, aligning material choices with regulatory and sustainability requirements and reducing regulatory risk for procurement teams.
Yes. The 85100E1415SY50 is part of the 851 series and is MIL-DTL-26482 SI qualified, indicating suitability for high-reliability aerospace, defense, and rugged industrial uses. Its 15 solder-cup contacts, backnut, and 1/3 bayonet coupling provide robust electrical performance and secure field connections in mission-critical equipment.
This receptacle supports 15 contacts, all configured as solder cup (Solder Cup) sockets (female). The solder-cup contacts enable reliable, field-terminable connections with standard harnesses, while the 1/3 bayonet coupling ensures repeatable mating in constrained spaces common to avionics and heavy machinery.
