MS27467 Circular Connectors

MS27497E8B35P Circular Connector for Bridge and Navigation Systems

The MS27497E8B35P is a 6-pin MIL-DTL-38999 Series II circular plug connector engineered for marine, shipboard, and industrial environments where compact, reliable electrical connections are required. Its Shell Size 8 housing allows integration of multiple signal lines in a small and rugged design.

Constructed from corrosion-resistant aluminum alloy, this connector is built to withstand vibration, saltwater, and harsh industrial conditions, making it ideal for navigation, communication, and control systems. The bayonet coupling ensures secure, vibration-resistant mating, while crimp termination guarantees stable electrical performance.

With IP67 sealing, the MS27497E8B35P protects against dust, moisture, and environmental contaminants, ensuring consistent operation in extreme conditions. Its wide temperature range from -65°C to +175°C makes it suitable for demanding marine and industrial applications.

Key Selection Considerations

• Pin Count and Layout: The 6-pin configuration suits moderate signal or low-power control circuits typical of bridge instrumentation and navigation repeaters.
• Mating Interface: As a MIL-DTL-38999 Series II plug, it mates with the corresponding Series II receptacle; confirm the exact shell size and insert arrangement before ordering.
• Environmental Rating: IP67 sealing supports exposed deck or equipment-room installations where splash, spray, or dust ingress is a concern.
• Mounting and Termination: Crimp termination requires the correct contact tooling and backshell for cable entry; verify the recommended wire gauge range for your harness.

Application Fit and Boundaries

This connector is well suited for navigation consoles, communication interfaces, sensor links, and control loops on vessels and offshore equipment where space is limited but reliability is critical. The aluminum alloy shell and gold-plated brass contacts provide a stable signal path in salt-laden air.

It is not intended for high-current power distribution, subsea (continuously submerged) use, or applications requiring frequent unmating under load. For underwater or high-vibration rotating applications, confirm the sealing and locking requirements with your engineering team before selection.

Configuration and Mating Dependencies

Before ordering, confirm the following with your supplier:

• Mating receptacle part number and shell size compatibility
• Insert arrangement and contact positions for your wiring diagram
• Required backshell, strain relief, or conduit adapter for cable entry
• Wire gauge and crimp tooling for the contacts
