MIL-DTL-38999 MS27467 Circular Connectors

MIL-Spec MS27467 Circular Connectors for Military and Industrial Systems

MS27467 circular connectors are high-performance interconnect solutions built to MIL-DTL-38999 specifications, designed for secure electrical connections and reliable operation under demanding conditions. These connectors are suited for aerospace, defense, transportation, and advanced industrial machinery where mechanical robustness and environmental resistance are critical.

This page helps engineers and procurement teams evaluate the MS27467 series by covering construction, coupling, contact arrangements, application fit, and the information needed to confirm a compatible configuration.

Rugged Construction for Harsh Environments

The MS27467 series is built with a durable aluminum alloy housing and PTFE insulators, providing strong resistance to mechanical stress, moisture, and vibration. This construction protects internal contacts and supports stable operation in environments with temperature fluctuations and continuous movement.

Key environmental advantages include:

• Strong vibration resistance for mobile and rotating equipment
• Reliable operation across extreme temperature ranges
• High mechanical durability for repeated mating and unmating
• Protection against moisture and contaminants

These features make MS27467 connectors suitable for critical systems where connection integrity cannot be compromised.

High-Density Multi-Pin Connectivity

MS27467 connectors support multiple contact arrangements, allowing power, signal, and data to be transmitted within a single compact circular interface. The 19-pin configuration with gold-plated brass contacts provides stable electrical performance and corrosion resistance.

This high-density design offers several benefits for system designers:

• Reduced wiring complexity compared to multiple single-pin connections
• Efficient use of installation space in confined equipment
• Simplified equipment assembly and maintenance
• Reliable multi-channel signal transmission

With various shell sizes and contact configurations available, MS27467 connectors can be adapted to meet the needs of different electrical systems.

Secure Bayonet Coupling for Stable Connections

MS27467 connectors feature a bayonet coupling mechanism that ensures a firm and reliable connection between mating parts. This locking system helps prevent accidental disconnection and maintains stable electrical contact during operation, particularly in environments where equipment experiences continuous vibration, movement, or mechanical stress.

The secure connection mechanism helps maintain signal integrity and consistent power transmission in demanding applications.

Integration with Standard Military Connector Systems

Because MS27467 connectors follow established military specifications, they are designed to mate with standardized components used in aerospace and defense systems. This compatibility allows engineers to integrate the connectors into existing systems without extensive modifications, supporting consistent performance and interchangeability across different equipment platforms.

Selection Considerations and Inquiry Checklist

To confirm the correct MS27467 connector for your application, verify the following details before ordering:

• Mating requirement: Confirm whether you need a plug or receptacle, and the gender of the contacts (male or female)
• Pinout or drawing: Provide the wiring diagram or contact arrangement to ensure correct pin assignment
• Cable outside diameter: Specify the cable diameter to confirm proper strain relief and sealing
• Conductor size: Provide the wire gauge to verify contact compatibility
• Electrical load: State the operating current and voltage for your application
• Environmental conditions: Describe the temperature range, vibration, and moisture exposure
• Order quantity: Indicate the required volume for pricing and lead time

Suitable and Unsuitable Applications

MS27467 connectors are well suited for military, aerospace, and industrial systems that require rugged, high-density connections with secure bayonet coupling. They are less suitable for applications requiring frequent rapid disconnection, where a push-pull or breakaway design may be more appropriate, or for environments where a non-metallic, lightweight housing is preferred.
