The MIL-DTL-26482 SI qualification supports compliance and reliable performance in aerospace, defense, and industrial equipment, enabling audit-ready programs and reduced qualification risk. In practice, customers gain predictable mating performance under vibration and thermal cycling, which translates to fewer field failures and lower warranty costs. The 18 solder-cup contacts deliver high channel density within a compact aluminum shell, simplifying wiring schemes and reducing harness complexity while preserving signal integrity. The combination of backnut, straight backshell, and 1/3 bayonet coupling yields fast, secure mating with proven retention in high-vibration environments, minimizing maintenance downtime. Cadmium plating enhances corrosion resistance for years of reliable service, while the 14-size shell supports compact, lightweight interconnects in constrained spaces. Operating from -40 °C to 125 °C broadens serviceable temperature ranges for aircraft, robotics, and industrial equipment, helping you meet stringent performance targets without overdesign.

FAQs
The 85100E1418S50 uses a square flange receptacle with a backnut and straight backshell to simplify alignment and installation in tight enclosures. The 18-contact configuration provides high channel density without increasing overall length, while the backnut retains the assembly under vibration. This combination reduces field adjustment time and improves first-pass mating reliability for aerospace and industrial harnesses.
This receptacle supports 18 contacts, all configured as Socket (Female) with Solder Cup terminations. The solder cup design offers robust, vibration-resistant connections suitable for high-density interconnects in demanding environments. With 18 terminals, it balances signal distribution and power delivery, enabling efficient harness design for complex equipment and reducing the need for multiple separate connectors.
Yes, the 85100E1418S50 is specified for a wide operating temperature range from -40 °C to 125 °C, making it suitable for cold starts, high-temperature operations, and extreme field conditions. This capability supports reliable performance in aerospace, defense, and industrial automation where temperature swings and thermal cycling are common, minimizing the risk of contact degradation and connector failure.
The product is MIL-DTL-26482 SI qualified, reflecting compliance with a recognized military interconnect standard. The specification also notes REACH environmental considerations, and cadmium plating for corrosion resistance. Specific certifications beyond MIL-DTL-26482 SI (such as SIL, CE, or IP ratings) are not listed in the provided data; users should verify with the supplier for any additional regulatory requirements relevant to their project.
Key considerations include using the backnut and straight backshell to ensure repeatable mating in vibration-prone environments, and leveraging the 1/3 bayonet coupling for secure retention during field servicing. The 18-contact configuration simplifies harness routing, while cadmium plating and aluminum shell provide corrosion resistance and lightweight construction. Ensure proper mating alignment, torque control on mounting hardware, and adherence to Souriau 851-series compatibility when integrating with ancillary components.
