Feature → Business Impact → Application: MIL-DTL-26482 SI qualification provides proven interconnect performance under military and aerospace standards, reducing risk of connector failure in harsh environments and improving system uptime during critical missions. This translates to lower maintenance costs and greater mission assurance in defense equipment and industrial automation systems requiring robust MIL-style interfaces. Feature → Business Impact → Application: Five-position (5) contact capacity enables compact harness design without compromising signal integrity, enabling higher density installations in avionics and robotics where space is at a premium. Application includes aerospace harnesses and rugged industrial controls that demand reliable, multi-contact connections. Feature → Business Impact → Application: Cadmium plating on an aluminium shell delivers corrosion resistance and EMI resilience, extending service life in harsh environments such as marine, offshore, or dusty factory floors while maintaining strong electrical performance over time. Feature → Business Impact → Application: 1/3 bayonet coupling with a straight backshell and adaptor supports quick mating/demating cycles and robust vibration resistance, minimizing downtime during field repairs or installation campaigns in heavy equipment and automated lines. Feature → Business Impact → Application: Square flange receptacle with a 48 mm length and 28.9×28.9 mm footprint creates a compact yet durable interface suitable for space-constrained control panels and avionics bays, enabling lighter, faster assemblies without sacrificing reliability. Feature → Business Impact → Application: Operating temperature range -40 to 125 °C ensures stable performance in extreme climates and on machinery exposed to thermal cycling, such as outdoor automation crates, aerospace ground support equipment, and rugged industrial machines. In practice, these characteristics support easier procurement, standardized parts usage, and predictable maintenance planning for systems engineers and buyers.

FAQs
Yes. The 85100AC145PZ50 is designed as a square flange receptacle in the 851 series family and ships with a connector option suitable for 851 backshells. Its straight backshell, Z orientation, and adaptor support alignments typical of MIL-DTL-26482 assemblies, enabling straightforward integration into existing harnesses and panel mountings while preserving mating integrity and vibration resistance.
The unit features 5 contacts in a 5-position layout, solder cup contact types, and a cadmium-plated aluminium shell (size 14). It uses a 1/3 bayonet coupling, supports a 48 mm length with overall dimensions near 28.9 mm (width) and 28.9 mm (height), and operates from -40 °C to 125 °C. These specs enable reliable signal transfer in harsh environments and precise fit within compact equipment enclosures.
Ideal for aerospace, defense, and rugged industrial automation where MIL-DTL-26482 interfaces are standard. The 85100AC145PZ50 excels in engine controls, avionics panels, military vehicles, and heavy machinery harnesses, delivering dependable connectivity under vibration, thermal cycling, and exposure to contaminants.
Yes. The product is REACH compliant, aligning with environmental and chemical safety standards. While specific RoHS details aren’t listed, the clear REACH reference supports regulatory alignment for many regulated markets, and MIL-DTL-26482 SI qualification provides assurance of performance in demanding applications.
Ensure proper alignment with the mate-and-backshell assembly, use the 1/3 bayonet coupling for secure mating, and verify solder cup terminations for clean, reliable connections. For maintenance, inspect cadmium-plated surfaces for any signs of wear, reseat the connector during routine checks, and keep environmental exposure minimal to extend service life in harsh operating environments.
