Key specs include 41 contacts in a 41-cavity layout, cadmium-plated aluminium shell, shell size 20, and a 44 mm length with 36.9 x 36.9 mm footprint. Contacts are Pin (Male) with Solder Cup terminations. Operating temperature ranges from -40 °C to 125 °C, and the coupling is 1/3 Bayonet for fast mating and secure retention.
Yes. The MIL-DTL-26482 SI qualification and REACH compliance make it suitable for aerospace, defense, and rugged industrial automation. Its high-contact density (41 circuits), lightweight aluminium shell, and corrosion-resistant cadmium plating support long-life deployments in harsh environments while maintaining reliable signal integrity in control cabinets and harness assemblies.
This connector is MIL-DTL-26482 SI qualified, signifying compliance with a recognized military standard for interconnects. It is also REACH compliant, supporting environmental and regulatory requirements for European supply chains. No CE or IP rating is specified in the provided data, so verify additional certifications as needed for your application.
The combination of a high-density 41-contact layout, cadmium plating, and an aluminium shell offers extended service life with reduced corrosion and maintenance needs. The straight adaptor and delivered-with connector simplify installation, reducing labor time and spare-parts variety, which translates to lower total cost of ownership in automated systems and mission-critical equipment.
