FAQs
Panel installation uses a square flange receptacle with a backnut backshell and 32 solder cup contacts. The mating interface is a 1/3 Bayonet coupling with a corresponding plug from the 851 series. Ensure correct orientation (Y) and secure the backnut to seal against environmental ingress; the unit ships delivered with connector for expedient assembly.
This receptacle supports 32 contacts in a 32-position layout with solder cup contact type. It features cadmium plating on an aluminium shell and operates from -40 °C to 125 °C. It is REACH compliant and MIL-DTL-26482 SI qualified, making it suitable for demanding environments in industrial and aerospace applications.
Yes. The 85100E1832SY50 is MIL-DTL-26482 SI qualified, uses a lightweight aluminium shell, and employs cadmium plating for corrosion resistance. Its backnut backshell and 1/3 Bayonet coupling design support rugged, vibration-prone applications, while the 32-contact arrangement accommodates dense signaling and power needs in challenging environments.
The connector is MIL-DTL-26482 SI qualified, indicating compliance with a recognized military standard for metal shell circular connectors converted to square flange receptacles. It also adheres to REACH environmental requirements. While cadmium plating is specified for corrosion resistance, verify local restrictions and RoHS-related guidelines in your region before use.
The aluminium shell and cadmium plating deliver durable, corrosion-resistant operation, reducing maintenance intervals in harsh environments. The 1/3 Bayonet coupling enables quicker mating, saving installation time, while the backnut backshell simplifies mounting. Overall, this design lowers lifecycle costs by improving reliability and reducing field service time in high-density signal/power networks.
