The first feature is the high-density contact count, with 39 solder cup pins in a square flange receptacle design. This enables more versatile I/O in compact panels, reducing enclosure footprint and simplifying wiring harnesses, which translates to faster assembly and lower assembly costs on the line. The business impact is clearer panel layouts and improved system reliability in control cabinets used for industrial automation, aerospace ground support, and rugged machinery. A second feature is the 1/3 bayonet coupling paired with a straight backshell and adaptor; the application benefit is quick, secure mating with predictable alignment, minimizing mis-mates and maintenance downtime in field installations. Third, cadmium plating on an aluminium shell delivers corrosion resistance while keeping weight low, supporting longer service life in aggressive environments and reducing total cost of ownership. Fourth, an operating temperature range from -40 °C to 125 °C ensures performance across harsh climates and thermal cycles common in aerospace and automated plants, which reduces warranty claims and spare part requirements. Fifth, the compact dimensions—53 mm length and 36.9 mm width/height with a 54.7 g weight—facilitate easier integration into space-constrained equipment and enclosures, improving overall equipment effectiveness. Finally, the option to deliver with connector accessories and the Y-oriented configuration aids routing and cable management, cutting installation time and enabling scalable multi-connector architectures for growing automation projects.
