Mil-DTL-26482 SI qualification provides a robust interface for high-vibration and wide-temperature conditions, reducing field failures and maintenance costs. In practice, this translates to longer mean time between failures and lower replacement part spend on critical projects. This is ideal for heavy equipment, aircraft ground support, and military panels where reliability is non-negotiable. The backnut with a square flange simplifies mounting and alignment, delivering a secure, sealed connection that speeds installation and minimizes rework in confined enclosures. The 34 solder cup contacts via the 34-position layout offer a dense, soldered interface with consistent electrical performance and signal integrity under shock. Cadmium plating and an aluminium shell deliver corrosion resistance and lightweight durability for demanding environments. The 1/3 bayonet coupling and W orientation enable quick mating and remating cycles, reducing maintenance downtime and service costs across fielded systems.

FAQs
This square flange receptacle uses a backnut mounting arrangement, simplifying panel installation and alignment in confined spaces. The 34-contact layout and W-oriented connection support clean cable routing and straightforward mating with compatible 1/3 bayonet couplings.
MIL-DTL-26482 SI qualification ensures a high-reliability interface under vibration, thermal cycling, and harsh environmental conditions. It reduces risk of intermittent connections and supports mission-critical applications in aerospace and industrial equipment.
Yes. The operating temperature range extends from -40 °C to 125 °C, enabling use in applications with substantial thermal variation common in aerospace, military, and heavy industrial equipment.
The receptacle is configured with Pin (Male) contacts delivered loaded in solder cups, providing a reliable soldered interface suitable for field assembly and maintenance.
The combination of inductive reliability (SI qualification), corrosion resistance (cadmium plating), and robust mounting reduces downtime, extends service life, and lowers lifecycle costs by minimizing replacements and rework in demanding environments.
