Feature → Business Impact → Application: The 85100E2236SW50 uses a square flange receptacle with backnut and straight backshell, enabling secure mounting and robust mechanical retention in tight panel spaces, which reduces field reworks and warranty claims in aerospace and industrial automation. This translates to a measurable improvement in installation time and system reliability for aircraft ground support, shipboard equipment, or rugged factory floors. Feature → Business Impact → Application: Cadmium plating and an aluminum shell provide corrosion resistance with weight savings, lowering lifecycle costs for outdoor, marine, or high-humidity environments while maintaining structural integrity. Feature → Business Impact → Application: 36 solder cup contacts in a 36-position layout deliver dense I/O in a compact footprint, enabling higher channel density on panels and reducing overall system size for control cabinets and vehicle electronics. Feature → Business Impact → Application: 1/3 Bayonet coupling and W orientation simplify mating and alignment during field upgrades or tight-space installations, reducing downtime and technician fatigue in high-mix, low-volume production lines. Feature → Business Impact → Application: Delivered with connector option and backnut accessibility streamline installation and serviceability, supporting faster spare-part provisioning and improved change management in regulated industries. Feature → Business Impact → Application: Operating temperature range of -40 °C to 125 °C supports reliability in extreme environments such as aircraft, defense, and heavy industrial plants, ensuring consistent signal integrity and mechanical performance across mission profiles.

FAQs
This receptacle employs a 1/3 Bayonet coupling mechanism and a straight backnut/backshell configuration, designed for quick alignment and secure mating. It uses 36 solder cup contacts configured in a 36-position layout and supports a W orientation for correct panel alignment, simplifying installation in constrained spaces.
Yes. The model is MIL-DTL-26482 SI qualified and features a square flange receptacle with a backnut, cadmium plating, and socket (female) solder cup contacts. With a 34.5 mm depth and 40 mm width/height, it fits tight panels while delivering reliable signal integrity for high-reliability programs.
The unit is REACH compliant, addressing key environmental regulations for materials in contact with humans and the environment. Its cadmium plating, aluminum shell, and sealed design also contribute to corrosion resistance in outdoor or demanding environments typical of aerospace, defense, and certain industrial settings.
Common use cases include aerospace harness assemblies, defense avionics, maritime electronics, and rugged industrial automation panels where a durable, RoHS-regulated, high-density 36-position interface is required. The backnut option and 1/3 Bayonet coupling support efficient field maintenance and rapid panel upgrades.
Installation is streamlined by the delivered-with-connector option and backnut assembly, reducing panel preparation time. The aluminum shell and cadmium plating enhance durability and corrosion resistance, while the 36-contact layout provides high channel density, lowering panel footprint and future upgrade costs in regulated industries.
