Feature → Business Impact → Application: The 85100E2025SW50 uses a square flange receptacle with a backnut, delivering robust mechanical retention and straightforward panel mounting, which translates to faster assembly on the shop floor and reduced risk of loose connections in vibration-heavy environments. Application: aerospace chassis, industrial automation panels, and military electronics where secure mating and vibration resistance are critical. Feature → Business Impact → Application: 25 contact positions in a single receptacle enables compact, high-density wiring with consistent pinout, improving harness routing and reducing interconnection complexity in compact equipment. Application: 25-position datasets in 851 series deployments for control cabinets and mobile platforms. Feature → Business Impact → Application: cadmium plating on an aluminium shell provides corrosion resistance and a lightweight yet durable enclosure, supporting longer service life in dirty or coastal environments. Application: outdoor or factory floor installations with exposure to humidity and contaminants. Feature → Business Impact → Application: 1/3 bayonet coupling offers rapid mating/demating without dedicated tools, reducing maintenance downtime and enabling field swaps. Application: field service and quick-replace scenarios in automation lines. Feature → Business Impact → Application: solder cup contacts deliver reliable wire terminations suitable for high-vibration settings, improving signal integrity and reducing contact resistance over time. Application: power and signal interfaces within the 851 series for consistent long-term performance.

FAQs
The 85100E2025SW50 is a square flange receptacle with a backnut, aluminium shell, and cadmium plating. It features a 34.5 mm length, 36.9 mm width and height, and weighs 44.7 g, with 25 solder cup contacts arranged in a 25-position layout to support compact, high-density wiring in harsh environments.
Yes. The 85100E2025SW50 is MIL-DTL-26482 SI qualified, ensuring rigorous aerospace and military performance. It also adheres to REACH environmental standards, features cadmium plating for corrosion resistance, and operates from -40 °C to 125 °C, making it suitable for extreme conditions and demanding field use.
This receptacle uses socket (female) solder cup contacts, with 25 contact positions. The solder cup design supports reliable wire terminations, vibration resistance, and straightforward field assembly, making it a practical choice for dense interconnects in control panels and deployable equipment.
The 1/3 bayonet coupling enables quick mating and unmating without tools, reducing downtime in maintenance and field swaps. Ensure mating with a compatible plug, align the orientation (W), and secure with the backnut for panel integrity. This design supports repeated cycles in rugged environments typical of aerospace and industrial automation.
With a robust aluminium shell, cadmium plating, and 25-contact density, the 85100E2025SW50 provides durable performance, reduced maintenance, and consistent electrical contact over time. Its MIL-DTL-26482 SI qualification and compact footprint enable standardized integration across automation cabinets, improving uptime, simplifying sourcing, and lowering total cost of ownership.
