FAQ

Q1: How do I choose between Male socket (P) and female socket (S) contacts for my MS3112 panel receptacle?
The choice depends on the direction of power or signal flow. For safety, pin (male) contacts are typically placed on the fixed panel receptacle if the primary power source comes from the cable plug side, preventing exposed live voltages when unmated.

Q2: Will Staconnector MS3112 receptacles mate with standard plugs from international brands?
Yes, absolutely. Because our connectors are manufactured to the strict geometric and performance criteria of MIL-DTL-26482 Series I, our pin or socket receptacles will mate seamlessly with any qualified brand plug matching the same standard.

Q3: Can Staconnector customize cable assemblies for both pin and socket receptacles?
Yes. As a direct factory manufacturer, we offer full OEM/ODM wire harness services. We can solder or crimp high-temperature cables directly to your chosen MS3112 configurations to deliver plug-and-play interconnect solutions.
