MS27467 Circular Connector Types and Core Counts

MS27467 Circular Connectors: MIL-DTL-38999 Series Overview

This catalog page presents the MS27467 Series of MIL-DTL-38999 circular connectors, covering available types and core counts for industrial and military applications. The information below helps engineers and procurement specialists evaluate key specifications including materials, waterproof ratings, operating temperature, electrical properties, and termination methods before selecting a part number.

Series Scope and Interface

The MS27467 designation refers to a specific connector configuration within the MIL-DTL-38999 standard. These connectors are designed for high-density circular interfaces requiring reliable performance in demanding environments. The catalog details multiple types and core counts so you can match the connector to your wiring layout and signal or power requirements.

Key Specifications to Review

When comparing MS27467 connectors, verify the following parameters against your application requirements:

• Materials: Shell, insulator, and contact plating options affect corrosion resistance and conductivity.
• Waterproof rating: Confirm the IP rating and whether it applies only when mated with the correct plug.
• Operating temperature: Check the continuous temperature range against your ambient and heat-rise conditions.
• Electrical properties: Review rated current, voltage, insulation resistance, and contact resistance for each core count.
• Termination method: Confirm whether the connector supports crimp, solder, or PCB termination for your assembly process.

Selecting the Right Core Count

Core counts determine how many circuits the connector can carry. Choose the configuration that matches your pinout without over-specifying, as larger shells add weight and panel space. The catalog lists available core counts so you can identify the smallest option that meets your circuit count and current requirements.

Application Fit and Environmental Limits

MS27467 connectors are commonly used in military, aerospace, and industrial equipment where vibration, moisture, and temperature extremes are present. However, verify that the specific part number's environmental ratings match your installation conditions. Derating may apply at elevated temperatures or when the connector is used at higher altitudes, so confirm tested values rather than assuming maximum ratings apply across all conditions.

Termination and Installation Considerations

Before ordering, confirm the termination method matches your production capability. Field-wireable versions allow on-site assembly, while factory-terminated versions require specifying cable length and contact arrangement in advance. Also verify the mounting style—whether the connector is a plug or receptacle, straight or angled—to ensure it fits your panel layout and cable routing.
