The 61-contact layout combined with 1/3 bayonet coupling delivers high-density signal and fast mating. Business impact: reduces wiring harness routing time and mating effort, lowering field labor and training costs. Application: ideal for aircraft, defense, and high-end industrial automation where space is constrained and reliability is non-negotiable. Solder Cup contact type provides secure, vibration-resistant terminations with soldered joints that maintain signal integrity in harsh environments. Business impact: improves electrical performance and reduces rework due to unreliable crimped connections. Application: servo drives, control panels, and robotics harnesses where permanent solder connections are preferred. Cadmium plating on the shell offers corrosion resistance and long-term durability in challenging environments. Business impact: extends service intervals and helps meet harsh-duty specs. Application: equipment exposed to moisture, salt spray, or temperature cycling in industrial or defense contexts. Aluminium shell and square flange receptacle with straight backshell provide weight savings and straightforward panel mounting. Business impact: lighter assemblies, easier installation, and compatibility with existing Eaton Souriau mounting standards. Application: avionics bays, machine builds, and cabinet assemblies where weight and space are critical. Operating temperature range from -40 °C to 125 °C ensures reliability across climate extremes. Business impact: reduces thermal management concerns and expands application scope without extra cooling. Application: outdoor automation, heavy equipment, and remote installations where ambient conditions vary widely.

FAQs
The 85100A2461P50 is designed for mission-critical, high-density wiring in aerospace, defense, and industrial automation. With 61 contacts arranged in a square flange receptacle and a 1/3 bayonet coupling, it supports dense interconnects while maintaining reliable mating in vibration-prone environments. It is well-suited for control panels, avionics bays, and rugged machinery where space and reliability matter.
To install, align the 85100A2461P50 with the mating Souriau interface, insert fully, and then rotate the 1/3 bayonet coupling to lock. Secure the square flange with appropriate mounting hardware and verify that all solder cups are clean and properly tin-ed before wiring. Using the connector as delivered with the mating interface ensures compatibility and reduces installation risk.
Key specs include 61 contacts with solder cup terminations, a straight backshell, aluminium shell, cadmium plating, and a square flange receptacle design. It operates from -40 to 125 °C and uses a 1/3 bayonet coupling for quick mating with robust retention. The configuration supports high-density, reliable interconnects in aerospace and industrial environments.
Yes. The 85100A2461P50 is MIL-DTL-26482 SI qualified and aligns with environmental considerations such as REACH. Cadmium plating provides corrosion protection, though local regulations may restrict cadmium use in some regions. In regulated settings, verify applicability and ensure proper handling and disposal per regional environmental rules.
The connector delivers reliability through solder cup terminations and a robust mechanical design, reducing maintenance cycles and in-field failures. Its high-density 61-contact arrangement and standard Souriau 851-series interfaces shorten wiring and assembly time, supporting faster deployments, lower total cost of ownership, and improved uptime for automation and control system projects.
