FAQs
Install by aligning the 3-contact layout with the mating connector, engage the straight backshell adaptor, and perform the 1/3 turn bayonet coupling to secure. Ensure solder cup contacts are properly tinned and soldered, with strain relief in the harness. Use the N orientation for correct harness routing and fit.
The unit supports 3 contacts in a 3-cavity layout, uses solder cup contact types, and employs a 1/3 bayonet coupling with a straight backshell. It features an aluminium shell with cadmium plating, 48 mm length, and 21x21 mm footprint, suitable for -40 to 125 °C environments.
Yes. The MIL-DTL-26482 SI qualification, aluminium shell with cadmium plating, and REACH compliance make it appropriate for aerospace ground equipment and vibration-heavy industrial automation where reliability and regulatory alignment are critical.
MIL-DTL-26482 SI qualification indicates the connector series meets specified performance criteria under MIL-DTL-26482, ensuring reliable mating, environmental tolerance, and mechanical robustness. It helps validate suitability for rugged applications and supports compliance with defense, aerospace, and high-reliability systems.
Cadmium plating on an aluminium shell delivers corrosion resistance with lightweight strength, extending service life and reducing replacement costs. Combined with a robust solder cup contact system, this reduces field maintenance, lowers warranty risk, and improves total cost of ownership in demanding environments.
