MIL-DTL-26482 SI qualified square flange receptacle with backnut delivers MIL-grade reliability and rugged sealing for mission-critical equipment, making it a solid choice for aerospace, defense hardware, and rugged factory automation where vibration and environmental exposure are common. It supports 16 solder-cup contacts in a compact 16-position layout, enabling high-density signaling and simpler terminations for harness assemblies and field service. The 1/3 bayonet coupling accelerates mating and reduces maintenance downtime, while the X-oriented orientation and delivered-with-connector option streamline installation in constrained panels. The aluminium shell size 20 keeps weight down without sacrificing strength, and the operating range from -40 °C to 125 °C ensures dependable performance across harsh climates. Cadmium plating offers corrosion protection in demanding environments, aligning with industrial and aerospace standards. REACH compliance further supports responsible procurement and supply-chain sustainability.

FAQs
The 85100E2016SX50 is a square flange receptacle from the 851 series that uses a backnut backshell and delivers 16 solder cup contacts in a compact footprint. It mates with standard 851-series connectors and aligns with the X orientation for straightforward installation. Ensure the panel cutout and mounting pattern match the square flange layout to preserve mating alignment and vibration resistance in aerospace or industrial automation applications.
This receptacle operates from -40 °C to 125 °C, supported by an aluminium shell (size 20) and cadmium plating for corrosion protection. The 16 solder cup contacts maintain reliable terminations under vibration, while the 1/3 bayonet coupling provides secure mating. For extended duty in hot environments, verify harness materials and mating hardware are rated accordingly to prevent thermal expansion issues.
Yes. The part is MIL-DTL-26482 SI qualified, offering MIL-grade performance for use in aerospace, defense, and rugged industrial equipment. Its square flange receptacle design, backnut backshell, and robust environmental characteristics support stringent installation standards. Always confirm program-specific requirements (such as IP ratings or additional certifications) with the procurement/spec team for your exact use case.
Ensure clean, properly tinned conductors and secure strain relief for the solder cup terminations. The 16-contact layout requires careful routing to avoid crossing and ensure even solder fillets. Use a compatible mating plug and correct torque on the backnut to maintain sealing and vibration resistance. Pre-inspect alignment with the X orientation to prevent mis-mating during field servicing.
The 85100E2016SX50 is REACH compliant, supporting environmental and regulatory expectations for European supply chains. It uses cadmium plating for corrosion resistance, a factor to review against customer metal plating policies. MIL-DTL-26482 SI qualification is a key performance and reliability indicator for critical applications. If your program requires IP ratings or RoHS specifics, verify with the supplier for exact documentation and test reports.
