MDC Circular MS Connectors are approved under the MIL-C-5015 military specification, with the MS prefix indicating compliance with stringent military standards.

The MS-3106A series are solid shell straight plug threaded connectors with polarizing keyways, designed for female socket type connections that mate with male pin receptacles.

The standard dielectric material is Diallyl Phthalate, providing dimensional stability, high arc resistance, and excellent insulation resistance under both humidity and thermal stress. Contacts are silver-plated with pretinned solder pockets, ensuring reliable electrical performance and corrosion resistance in demanding environments.

Industry Applications

Circular MS Connectors are widely used in aerospace, defense, industrial automation, telecommunications, and vacuum technology systems. Their high voltage and current ratings, rugged MIL-C-5015 compliance, and wide temperature tolerance make them ideal for aircraft power systems, radar and communication equipment, industrial machinery, and critical research instrumentation. These connectors provide secure, long-lasting electrical performance in harsh and mission-critical environments.
