The 85100E2025PZ50 is MIL-DTL-26482 SI qualified and uses a square flange receptacle with backnut, delivering proven performance under extreme conditions. This qualification reduces field failures and warranty costs, making it ideal for aerospace, defense, and rugged industrial control panels where reliable mating is critical. The 25-position layout with 1/3 bayonet coupling supports high-density wiring while maintaining secure, vibration-resistant connectivity that minimizes costly downtime in harsh environments. Cadmium plating paired with an aluminium shell size 20 enhances corrosion resistance and structural integrity for outdoor installations or equipment exposed to contaminants. Straight backshell and backnut simplify panel mounting and maintenance, enabling faster installation and easier field servicing. The Z orientation and delivered-with-connector option streamline harness integration, reducing assembly steps and mis-mating risk. Operating from -40 °C to 125 °C, the connector stays dependable across extreme temperatures common in industrial and aerospace applications.
