MS27473E14B35S 37-Pin Connector for Naval Radar Control Units

MS27473E14B35S Connector for Naval Radar Control Units

The MS27473E14B35S is a 37-pin circular connector engineered for naval radar control units and other maritime electronic systems. Its aluminum alloy shell and gold-plated brass contacts are designed to maintain secure signal transmission in demanding salt-air environments.

Key Selection Criteria for Maritime Applications

When evaluating this connector for a radar or control system, consider the following decision points:

• Pin count and layout: The 37-pin configuration supports dense signal routing for radar control interfaces; confirm the required contact arrangement against your system pinout.
• Electrical rating: Rated for 600V AC and 5A per contact, with high insulation resistance and low contact resistance for stable signal integrity.
• Environmental sealing: IP67 protection and a -55°C to +125°C operating range suit exposed deck and antenna installations.
• Termination method: Solder and crimp options allow integration with existing cable assemblies or field maintenance procedures.
• Mating compatibility: Verify the mating connector part number and shell size to ensure correct keying and polarization for your application.

Construction and Material Performance

The connector uses a rugged aluminum alloy housing with a corrosion-resistant finish, supported by high-quality thermoplastic or thermoset insulation. Contacts are brass with gold plating, providing consistent electrical performance and resistance to corrosion in humid, salt-laden environments.

Electrical and Environmental Verification

The MS27473E14B35S is rated for 600V AC and 5A per contact. It maintains insulation resistance of at least 5000 MΩ and contact resistance of no more than 5 MΩ, and is tested at 1500V AC for one minute to confirm dielectric strength. With an IP67 rating, the connector is dust-tight and protected against temporary water immersion, supporting reliable operation across a wide temperature range.

Suitable and Unsuitable Applications

This connector is well suited for naval radar control units, communication radar antennas, and other high-performance maritime electronic systems where reliability and precision are critical. It is not intended for subsea or continuously submerged installations, nor for high-current power distribution beyond its 5A per contact rating. For applications requiring higher current or deeper water protection, please consult our team for alternative options.
