FAQs
Installation begins with aligning the receptacle to the mating connector using the N orientation. Engage the 1/3 bayonet coupling to establish a secure mechanical and electrical connection, then secure the backshell adaptor and route conductors as specified. The solder cup contacts should be soldered with proper temperature control to ensure reliability in high-vibration environments.
Yes. The 85100A1623S50 is designed for MIL-DTL-26482 SI qualified interfaces, supporting a 23-position configuration with socket (female) contacts. Ensure correct mating polarization and backshell orientation, and verify that the connector family and shell size are compatible with your enclosure and panel cutouts.
The connector operates from -40 °C to 125 °C, covering extreme cold start conditions and hot-environment operation typical in aerospace and heavy industry. Plan for thermal cycling and ensure soldered joints are rated for repeated cycling within this range.
Industrial automation, aerospace, and defense applications benefit most. It is well-suited for high-density signal distribution in control consoles, aircraft assemblies, and rugged machinery where a compact, corrosion-resistant, MIL-spec receptacle is required.
The part is REACH compliant and uses cadmium plating, so verify your procurement and disposal practices align with environmental regulations and cadmium handling guidelines. Ensure compatibility with your project’s safety, quality, and regulatory requirements, including supplier qualifications for MIL-SPEC components.
