MIL-DTL-26482 SI qualified construction delivers reliable mating in extreme environments, reducing failure rates and enabling use in MIL-grade assemblies across aerospace and defense programs. The business impact is measurable: improved uptime, traceability, and consistency in performance. This design is well-suited for aircraft, ground support equipment, and heavy industrial automation where regulatory compliance and mission readiness drive procurement decisions. The 55-contact capacity enables dense wiring and multi-channel signal routing, supporting complex control networks while maintaining signal integrity and ease of maintenance. Cadmium plating on an aluminium shell provides corrosion resistance and a lighter footprint, translating to lower total cost of ownership in harsh outdoor or vibration-prone deployments. The 1/3 Bayonet coupling allows rapid mating and secure retention, reducing field maintenance time and risk of misconnection. Delivered with connector and a square flange receptacle footprint simplifies panel mounting and reduces installation steps, contributing to faster deployment and improved project schedules. Compatibility with straight backshell configurations enhances install flexibility in restricted enclosures and compact machines, while ensuring robust EMI performance in demanding environments.
