MIL-DTL-38999 MS27467 Circular Connectors

MS27473E14B35P Circular Connector for Engine Room and Monitoring

The MS27473E14B35P is a 37-pin MIL-DTL-38999 Series II circular plug connector, engineered for marine, shipboard, and industrial environments where high-density, reliable electrical connections are critical. Its Shell Size 14 housing allows integration of numerous signal and low-power circuits while maintaining a compact and rugged design.

Constructed from a corrosion-resistant aluminum alloy, this connector withstands saltwater, vibration, and harsh industrial conditions, making it ideal for navigation, communication, and control systems. The bayonet coupling ensures secure mating and unmating, providing vibration-resistant and stable connections.

Featuring crimp termination and IP67 sealing, the MS27473E14B35P delivers consistent electrical performance while protecting against dust, moisture, and environmental contaminants. Its wide temperature range from -65°C to +175°C guarantees reliable operation even in extreme conditions.

Key Advantages for Engine Room and Monitoring Applications

• 37-Pin High-Density Plug – Efficiently supports multiple circuits in limited space, ideal for engine room control and monitoring systems.
• Robust Environmental Sealing – IP67 protection for harsh marine and industrial conditions, safeguarding connections from moisture and contaminants.
• Durable Aluminum Alloy Shell – Corrosion-resistant and long-lasting, suitable for saltwater and demanding industrial environments.
• Bayonet Locking Mechanism – Ensures secure, vibration-resistant connections, critical for engine room equipment subject to continuous vibration.
• Wide Temperature Range – Reliable operation from -65°C to +175°C, accommodating extreme thermal conditions found in engine compartments.

Selection Considerations

When selecting the MS27473E14B35P for your application, verify the following:

• Mating Connector: Confirm the corresponding receptacle (socket) part number and shell size to ensure proper mating compatibility.
• Contact Arrangement: Verify the 37-pin layout matches your circuit requirements, including signal and power distribution.
• Cable and Termination: Ensure your cable diameter and wire gauge are compatible with the crimp termination contacts specified for this connector.
• Mounting Configuration: Determine whether a straight or angled plug, or a specific mounting style, suits your panel or bulkhead installation.

Application Boundaries

This connector is well-suited for engine room monitoring, shipboard control systems, navigation equipment, and industrial automation where high-density signal connections and environmental protection are required. However, it is not intended for high-current power distribution applications; verify current ratings against your load requirements. For applications exceeding the IP67 rating or requiring submersion, consult our team for alternative sealing options.

Installation and Maintenance Guidance

Proper installation is essential for achieving the rated environmental protection and mechanical reliability:

• Use the specified crimp tooling and follow the contact insertion and removal procedures to avoid damaging the gold-plated brass contacts.
• Ensure the bayonet coupling is fully engaged until a positive stop is felt, confirming a secure, vibration-resistant connection.
• Periodically inspect the sealing grommet and O-rings for wear or damage, especially in high-temperature engine room environments.
• When unmated, use protective caps to maintain the IP67 sealing integrity and prevent contamination of the contact cavity.
