FAQs
The 85100AC1214SW50 is a square flange receptacle designed to mate with MIL-DTL-26482 SI qualified interfaces. It uses a straight backshell with a 1/3 bayonet coupling and 14 solder cup contacts, offering reliable alignment and secure connection in vibration-prone environments. This makes it suitable for standardized aerospace and defense harness assemblies as well as compatible industrial automation panels.
Ideal for high-reliability applications, this connector supports aerospace and defense wiring, as well as demanding industrial automation environments. Its 14-contact layout enables dense interconnects, while the cadmium plating and aluminium shell provide corrosion resistance and lightweight strength. The product is well-suited for mission-critical equipment, avionics, and rugged machinery requiring robust environmental performance.
The 85100AC1214SW50 carries MIL-DTL-26482 SI qualification and REACH compliance, ensuring performance in harsh environments and adherence to environmental safety standards. The combination of these certifications supports aerospace, defense, and industrial programs that require both military-spec interconnect reliability and regulatory compliance, including heavy-use settings with exposure to contaminants.
Installation relies on the straight backshell adaptor and 1/3 bayonet coupling to achieve secure mating under vibration. The contact arrangement is socket (female) with solder cup terminations, and the connector is delivered with the mating accessory option. Ensure correct orientation (W) and verify that all 14 contacts are properly soldered before mating with the corresponding plug, minimizing misalignment risks.
The connector measures 48 mm in length and 26.5 mm in both height and width, with a 14-contact configuration. Weight is approximately 23 g, and operating temperature ranges from -40 °C to 125 °C. Cadmium plating and aluminium shell enhance corrosion resistance and strength-to-weight, reducing maintenance cycles and improving uptime in harsh environments, which directly improves total cost of ownership.
