MS27473E14B35P Series I MIL-DTL-38999 Circular Connector

OHS Circular Connector

MS27473E14B35P Series I MIL-DTL-38999 Circular Connector Overview

The MS27473E14B35P is a Series I MIL-DTL-38999 circular connector designed for aerospace, defense, and other high-reliability applications. Its rugged construction supports secure connections in environments with high vibration, temperature fluctuations, and demanding operational conditions. This 6-pin connector is available in male or female configurations, with an aluminum alloy housing and gold-plated brass contacts.

Why Choose the MS27473E14B35P for Critical Systems

When selecting a connector for avionics, defense electronics, or industrial systems, engineers evaluate mechanical endurance, electrical stability, and environmental sealing. The MS27473E14B35P addresses these priorities through its Series I MIL-DTL-38999 design, which is recognized for reliable performance in high-vibration and thermal cycling conditions.

• Proven military standard: Series I MIL-DTL-38999 is a widely specified interface for aerospace and defense platforms.
• Lightweight yet durable: Aluminum alloy housing reduces weight while maintaining structural integrity.
• Stable electrical performance: Gold-plated brass contacts support low contact resistance and long-term connection stability.
• Application flexibility: Suitable for avionics, defense electronics, and industrial control systems requiring secure circular interconnects.

Application Scope and Environmental Fit

The MS27473E14B35P is intended for use in systems where connection integrity under mechanical stress is critical. Typical applications include aircraft avionics bays, military communication equipment, and industrial automation where shock and vibration are present. The connector's Series I coupling mechanism provides a threaded mating interface, which is preferred in applications where accidental disconnection must be minimized.

For applications requiring a bayonet coupling style, review the MS27473E12B4P MIL-DTL-38999 Series II 6-Pin Bayonet Coupling Connector to compare mating options. For additional Series I configurations, the MS27473E12B4S MIL-DTL-38999 Series I 4-Pin Circular Connector offers a different pin arrangement.

Selection Considerations and Configuration Boundaries

Before specifying the MS27473E14B35P, confirm the following application requirements to ensure correct mating and installation:

• Mating side: Verify whether the mating connector is a plug or receptacle with the corresponding gender and shell size.
• Pinout and wiring: Provide the required pin assignment and conductor sizes to confirm contact compatibility.
• Cable preparation: Confirm the cable outside diameter and conductor insulation dimensions for proper termination.
• Environmental exposure: Define the operating temperature range and whether the connector will be exposed to fluids or continuous vibration.
• Mounting style: Specify whether panel mounting, cable mounting, or free-hanging installation is required.

Installation and Mating Guidance

Proper installation of the MS27473E14B35P requires attention to the mating interface and cable preparation. Ensure the mating connector is the same Series I MIL-DTL-38999 shell size and insert arrangement. Confirm the contact termination method matches the supplied tooling and that the cable jacket fits within the designated cable entry range. For detailed dimensional and electrical values, refer to the Technical Specifications section.
