Feature → MIL-DTL-26482 SI qualification provides mission-critical reliability in extreme environments. This certification supports consistent electrical performance under vibration, EMI exposure, and wide temperature ranges, reducing field failures and warranty costs. Application: aerospace, defense, and rugged industrial automation equipment require this level of interconnect assurance for mission success. Feature → 27 contacts in a compact 27-position arrangement with pin (Male) solder cup contacts. Business impact: high-density signal and power paths with reliable solder terminations improve harness integrity and minimize assembly time. Application: panel-to-harness connections in control panels, robotics, and outdoor machinery where space is at a premium. Feature → Cadmium plating on an aluminium shell delivers corrosion resistance with lightweight construction. Business impact: longer service life in humid or chemical environments and easier field maintenance. Application: outdoor installations, maritime applications, and aerospace equipment where weight and durability matter. Feature → 1/3 Bayonet coupling with a straight backshell adaptor enables quick, tool-free mating and secure retention. Business impact: reduces installation time, lowers training requirements, and minimizes risk of mis-mating. Application: on-site assembly in confined spaces and rapid field replacements in automation systems. Feature → Operating temperature range from -40 °C to 125 °C accommodates broad industrial and aerospace applications. Business impact: expanded operational envelope lowers the need for multiple part numbers and simplifies spares. Application: automation equipment, HVAC, heavy machinery, and rugged control cabinets.

FAQs
The installation begins with aligning the square flange receptacle to the mating interface, then engaging the 1/3 bayonet coupling to secure the connection. Ensure the backshell adaptor is properly seated and the connector is delivered with the mating hardware. This design supports quick, tool-free mating while maintaining a robust mechanical lock for vibration-heavy environments.
This receptacle uses pin (Male) contacts with Solder Cup terminations, loaded for immediate integration into harnesses. Solder cups provide reliable, repeatable terminations with good strain relief when soldered correctly, reducing the risk of loose connections in rugged applications and enabling solid signal integrity for 27-contact configurations.
The series supports an operating range from -40 °C to 125 °C, enabling use in extreme temperatures and challenging environments. It also features cadmium plating and aluminium shell to enhance corrosion resistance and weight efficiency, with REACH compliance to meet environmental and regulatory expectations in many regions.
Yes. The MIL-DTL-26482 SI qualification specifically targets high-reliability interconnects used in aerospace and defense. Its 27-contact, 1/3 bayonet coupling, and square flange receptacle format also aligns with rugged industrial automation requirements, making it a versatile choice for systems needing durable, field-serviceable connectors.
This is a square flange receptacle with straight backshell orientation (Adaptor). It includes a delivered-with-connector option for streamlined integration, and its 27-contact layout fits compact assemblies. The standard mounting footprint simplifies compatibility with existing panels and interface hardware, reducing custom mounting time and ensuring reliable alignment during installation.
