MIL-DTL-26482 SI qualification is embedded in the Eaton Souriau 85100E2025PX50, delivering reliable electrical performance under vibration, shock, and temperature cycling. This ruggedness translates into lower field failures and longer maintenance intervals for packaging lines, robotics, and process automation where downtime costs money. The combination of a square flange receptacle and backnut enables secure panel mounting, while the 25 solder cup contacts support robust power and signal distribution. With 25 positions, it reduces routing complexity and minimizes wiring errors during panel assembly, accelerating commissioning of control cabinets and distributed I/O networks. The 1/3 Bayonet coupling provides fast, tool-free mating and unmating, cutting installation time during builds or upgrades. Paired with a straight backshell, it maintains alignment in tight spaces and mitigates ingress risk in dust-prone environments. Cadmium plating on an aluminium shell yields corrosion resistance with light weight, suitable for industrial floors and coastal operations, while shell size 20 and a 34.5 mm length support compact panel layouts. Operating from -40 °C to 125 °C broadens application windows for outdoor enclosures, high-temperature equipment, and automotive assembly lines, ensuring reliable performance without extra thermal management. Delivered with connector and orientation X simplifies sourcing and integration with existing Eaton Souriau ecosystems, reducing BOM complexity and enabling faster time-to-operate in mixed-brand installations.

FAQs

To install, align the connector orientation X with the mating half, mount the square flange using the backnut for secure panel fixation, and connect the solder cup contacts on the male side. Verify 1/3 bayonet coupling engages fully, then mate and test continuity across all 25 cavities. Ensure compliance with panel cutout dimensions and environmental sealing requirements.
MIL-DTL-26482 SI qualification guarantees performance under vibration, shock, and temperature cycling, providing consistent electrical characteristics in demanding applications. Coupled with REACH compliance and cadmium plating on aluminium shell, the connector resists corrosion and maintains reliable contact integrity in industrial, coastal, and automation environments.
The receptacle supports 25 contacts in a 25-position layout with male solder cup contacts. It uses a 1/3 bayonet coupling for quick mating, and the backnut-backed square flange design ensures a secure, panel-mounted interface suitable for dense power and signal distribution in control cabinets.
The provided data specifies MIL-DTL-26482 SI qualification and REACH compliance but does not list CE or IP ratings. For CE or IP guidance, consult the manufacturer or distributor technical sheets to confirm applicable ingress protection levels or regulatory certifications for your specific use case.
Benefits include lower total cost of ownership from reduced maintenance due to robust vibration resistance and corrosion protection, faster installation thanks to the 1/3 bayonet coupling and backnut panel mounting, and simplified field servicing via 25 solder cup terminations. These factors contribute to shorter downtime, improved uptime, and more predictable long-term performance in automated production lines.
