MIL-DTL-26482 SI qualification ensures the 85100E1832PZ50 delivers proven, high-reliability performance in shock and vibration environments. This translates to reduced field failures, lower maintenance costs, and longer service life in aerospace avionics, rugged automation panels, and industrial control rooms. The 32-position square flange receptacle with backnut optimizes panel density, reducing enclosure footprint and simplifying routing for high-density installations. Cadmium plating paired with an aluminium shell delivers excellent corrosion resistance and weight efficiency, supporting outdoor or harsh-indoor use without compromising durability. Loaded with male solder cup contacts, the connector delivers secure, soldered wiring paths that resist loosening under vibration, improving long-term signal integrity. The 1/3 Bayonet coupling and straight backshell enable quick, repeatable mating and dependable retention in assembly lines and field service scenarios. Operating from -40 °C to 125 °C, this unit supports wide ambient ranges common in industrial and military environments, while REACH compliance provides confidence in environmental responsibility. Compatibility with the Souriau 851-series ecosystem ensures predictable interchangeability across designs, reducing spare-part diversification and optimizing procurement workflows.

FAQs
The 85100E1832PZ50 is a 32-position square flange receptacle designed to align with typical Souriau 851-series interfaces. Its straight backshell and backnut enable straightforward panel mounting, while the 32-contact layout matches common high-density backplanes. This compatibility minimizes redesign, reduces BOM complexity, and accelerates integration in control cabinets and rugged equipment.
To ensure reliable mating, align the connector orientation to Z, insert the receptacle until the terminations seat, then engage the 1/3 bayonet coupling with a controlled twist to full engagement. Tighten the backnut securely but avoid over-torquing. Verify solder cups are properly reflowed or cabled with secure, strain-relieved connections to sustain vibration and thermal cycling.
This receptacle operates from -40 °C to 125 °C, making it suitable for aerospace, military, and rugged industrial automation environments where temperature extremes and thermal cycling are common. The aluminium shell keeps weight manageable, while cadmium plating protects against corrosion in challenging field conditions.
The 85100E1832PZ50 carries MIL-DTL-26482 SI qualification, indicating conformity to that widely adopted military-standard interface. It also adheres to REACH environmental requirements, supporting safe chemical usage and compliance in regulated markets. These certifications help reduce compliance risk in defense, aerospace, and high-end industrial applications.
Choosing this high-density square flange receptacle reduces panel footprint and wiring complexity, lowering assembly time and cabling costs. The robust cadmium finish, large operating range, and reliable solder cup contacts minimize field maintenance and downtime, delivering improved equipment uptime and predictable lifecycle costs in automated control panels and rugged installations.
