MS27467 Circular Connectors

MS27473E8B35S 6-Pin Circular Connector – Shell Size 8, Series II, IP67 Waterproof

The MS27473E8B35S is a 6-pin MIL-DTL-38999 Series II circular connector, engineered for marine, shipboard, and industrial applications where reliability and compact design are critical. With a Shell Size 8 configuration and durable bayonet-coupled socket contacts, this connector ensures stable electrical performance in harsh environments.

Application Scope and Key Benefits

Constructed from a corrosion-resistant aluminum alloy shell, the MS27473E8B35S withstands saltwater, humidity, vibration, and shock, making it suitable for navigation, communication, and control systems on naval and offshore vessels. Its IP67 sealing supports dependable operation in wet or exposed conditions, while crimp termination provides consistent connections and simplifies installation and maintenance.

Selection Considerations for Buyers

• Mating and Mounting: Confirm whether you need a plug or receptacle, and verify the bayonet coupling style matches your existing MS27473 or MS27467 series hardware.
• Contact and Cable Range: The 6-pin layout with gold-plated brass contacts supports signal and low-power circuits; check your cable diameter against the recommended crimp contact range before ordering.
• Environmental Fit: The IP67 rating is verified for mated conditions; for unmated protection or prolonged submersion, confirm your application requirements with the factory.
• Installation Planning: Crimp termination requires appropriate tooling and backshell selection; review the assembly drawing to ensure your panel or cable entry matches the shell size 8 footprint.

Construction and Reliability Highlights

The compact 6-pin layout allows designers to integrate multiple signal paths without increasing panel space, offering a space-efficient, high-reliability solution for critical systems. The aluminum alloy housing and gold-plated contacts are selected for corrosion resistance and stable conductivity in salt-laden atmospheres.

Suitable and Unsuitable Use Cases

This connector is well suited for shipboard electronics, offshore instrumentation, and industrial control cabinets where a compact, sealed, and vibration-resistant interface is required. It is not intended for high-current power distribution, subsea permanent immersion, or applications requiring frequent unmated exposure to water; for those, confirm the appropriate series and sealing options with your engineering team.
