MS27467 Circular Connectors

MS27473E12B4S Series I Circular Connector Overview

The MS27473E12B4S is a MIL-DTL-38999 Series I circular connector designed for reliable electrical connections in mission-critical equipment. Its rugged shell and precise contact configuration support stable signal and power transmission in demanding environments.

Key Selection Criteria

When evaluating this connector for your application, consider the following decision points:

• Configuration: This model is a 4-pin socket (female) variant. Confirm your mating plug requirement, such as the MS27467 series, to ensure correct pairing.
• Environmental Fit: The aluminum alloy housing and gold-plated brass contacts are suited for applications requiring corrosion resistance and stable conductivity. Verify your operating temperature and vibration levels against the specification.
• Application Scope: Typical uses include aerospace electronics, military communication systems, and industrial control equipment. Assess whether your specific environment demands additional sealing or strain relief.

Application and Installation Guidance

This connector is intended for high-reliability systems where secure coupling and vibration resistance are critical. For installation planning, confirm the following with your design team:

• Cable outside diameter and conductor size for proper termination.
• Required pinout or wiring diagram to match your system's signal and power layout.
• Mounting style and panel cutout dimensions to ensure mechanical fit.

For related configurations, review the MS27467 Circular Connectors to understand mating plug options. If your project involves a different pin count, the MS27473 10-Pin MIL-DTL-38999 Series II Circular Connector may offer an alternative.

Suitable and Unsuitable Use Cases

Suitable: This connector is appropriate for fixed or limited-motion installations in controlled industrial or military environments where its rated electrical and mechanical performance is not exceeded.

Unsuitable: It is not recommended for applications requiring frequent mating cycles under high vibration without additional locking mechanisms, or for environments where continuous submersion is expected unless the system provides external protection.
