MIL-DTL-38999 MS27467 Circular Connectors

MS3116F14-19S Circular Connector for Autopilot Control Systems

The MS3116F14-19S is a 19-pin circular connector designed for reliable signal and power transmission in autopilot control systems and other marine and shipboard electronics. Its bayonet coupling and corrosion-resistant construction support secure, vibration-resistant connections in demanding maritime environments.

Key Selection Considerations

• Pin Configuration: 19-pin layout with brass contacts plated in gold for stable conductivity and corrosion resistance.
• Coupling Mechanism: Bayonet quick-lock coupling provides secure mating and reduces the risk of loosening under shock or vibration.
• Environmental Protection: IP67-rated sealing supports operation in wet or humid conditions typical of marine installations.
• Temperature Tolerance: PTFE insulation and housing materials support a wide operating range from -55°C to +200°C.

Application Scope and Suitability

This connector is suited for autopilot control systems, navigation equipment, communication interfaces, and other shipboard electronics where dependable signal integrity is required. Its aluminum alloy housing with optional stainless steel construction offers durability against saltwater exposure and mechanical stress.

For system integrators and marine engineers, the MS3116F14-19S provides a practical solution when a 19-pin interface with bayonet locking and IP67 protection is specified. It is less suitable for applications requiring high-current power distribution or where a threaded coupling is mandated by installation standards.

Installation and Mating Guidance

Before specifying, confirm the mating plug or receptacle configuration, contact arrangement, and cable entry requirements. Provide the following details to ensure correct matching:

• Mating connector part number and gender (plug or receptacle)
• Pinout diagram or contact assignment for your autopilot system
• Cable diameter and termination method (solder, crimp, or PCB)
• Required mounting style (panel, cable, or in-line)

Quality and Reliability Notes

The connector uses PTFE insulators and gold-plated brass contacts to maintain low contact resistance and high insulation resistance. These material choices support stable performance across the rated temperature range. For detailed electrical ratings and dimensional data, refer to the Technical Specifications section.

Inquiry Checklist

When requesting a quotation or sample, include your application environment, mating connector details, cable specifications, and any specific test or certification requirements. This helps confirm the correct configuration before ordering.
