27-position, 27 cavity arrangement with solder cup contacts enables high-density interconnects and reliable signal paths in space-constrained panels. This directly reduces harness complexity and panel footprint, translating to faster assembly, easier maintenance, and lower installation costs in aircraft, defense equipment, and industrial automation harnessing. Cadmium plating paired with an aluminium shell delivers corrosion resistance and durability across operating temperatures, extending service life in harsh environments and reducing lifecycle costs. The backshell adaptor with a straight backshell simplifies mounting on flat panels, while the X orientation guarantees correct mating alignment, minimizing mis-mates during field servicing. The 1/3 bayonet coupling speeds assembly and field replacement, improving throughput during production lines and on-site repairs. MIL-DTL-26482 SI qualification alongside REACH compliance ensures regulatory alignment and traceability for aerospace programs and compliant supply chains.
