FAQs
This receptacle uses a backnut and straight backshell with a Z orientation to simplify panel mounting. The 1/3 bayonet coupling enables quick mating, while the solder cup contacts provide reliable terminations. Ensure matching connector halves are aligned to achieve proper impedance and seal integrity, and verify panel cutouts accommodate the 40 mm height and 40 mm width.
Key specs include 32 contacts in a 22-shell size aluminium shell, cadmium plating, and 34.5 mm depth with 40 mm height. It supports operating temperatures from -40 °C to 125 °C, features a square flange receptacle design, delivered with connector, and uses solder cup contacts for robust, low-impedance terminations.
Yes. It is MIL-DTL-26482 SI qualified, with an aluminium shell and cadmium plating for corrosion resistance, and a wide operating temperature range. Its 1/3 bayonet coupling and backnut ensure secure mating under vibration, making it well-suited for aerospace, defense, and rugged industrial applications.
The connector is MIL-DTL-26482 SI qualified and REACH compliant, providing confidence in performance under stringent regulatory and environmental expectations. This supports long-term supply chain stability and reduces compliance-associated risk in regulated industries.
With 32 contacts in a compact aluminium shell, quick mating via 1/3 bayonet coupling, and the delivered-with-connector option, installation time and field labor are reduced. The rugged design minimizes field failures and maintenance cycles, while standardized parts simplify spares planning and long-term ROI for OEMs and integrators.
