What does MIL-DTL-38999 compliance mean?

It ensures the connector meets military standards for environmental sealing, electrical performance, vibration resistance, and durability in extreme conditions.

What is the difference between socket (S) and plug connectors?

Socket contacts (S) receive pins. This part mates with a complementary MS3101A plug connector with the same shell size and pin arrangement.

What is the operating temperature range?

-55°C to +125°C, meeting military environmental specifications for extreme thermal cycling.

Is this connector rated for vibration and shock?

Yes, MS3101A connectors are designed to withstand vibration, shock, thermal cycling, and moisture typical of aerospace and defense applications.

What industries use this connector?

Primarily aerospace, defense, military equipment, but also industrial control, marine, and off-road equipment requiring sealed, rugged connections.

Can I substitute this with a commercial circular connector?

Not recommended. Military connectors have superior sealing, contact reliability, and environmental specifications. Substitution requires engineering review.
