FAQs
This 85100A2236S50 uses a 1/3 Bayonet coupling with a square flange receptacle, straight backshell adaptor, and a N orientation. Panel cutouts should accommodate a 36-contact, 22-shell-size module with a 40 mm x 40 mm footprint. Ensure proper alignment with the 36-position contact array and secure latching to achieve vibration resistance. Using the included connector with a compatible panel mount and mating connector ensures reliable field installation and reduces assembly time.
The unit provides 36 solder cup contacts within a 36-cavity layout, housed in an aluminium shell with cadmium plating. It operates from -40 °C to 125 °C, offering robust performance across extreme temperatures. The solder cup contacts facilitate straightforward soldering to harnesses, while the 1/3 Bayonet coupling ensures secure electrical continuity under vibration and shock.
Yes. The 85100A2236S50 is MIL-DTL-26482 SI qualified, which is a key military specification for high-reliability interconnections. It also carries REACH environmental compliance and cadmium plating for corrosion resistance, making it well-suited for aerospace, defense, and demanding automation environments where long service life and reliability are critical.
Core certifications include MIL-DTL-26482 SI qualification and REACH compliance. Material considerations include an aluminium shell, cadmium plating for corrosion protection, and a square flange receptacle design. These factors collectively support offshore, airborne, and harsh-environment deployments while meeting industrial health and safety expectations.
The combination of high-contact density, rugged aluminium housing, and robust environmental protection reduces maintenance frequency and field repair time. The SI qualification and durable plating minimize downtime during mission-critical operations, delivering lower lifecycle costs and higher uptime in aerospace, defense, and automated manufacturing environments.
