MS27467 Circular Connector Overview

The MS27467 series is a family of circular, bayonet-coupling connectors designed for military and industrial applications where reliable power and signal transmission under demanding conditions is required. This page details the materials, waterproof ratings, operating temperature, electrical performance, and termination options available across the series, helping you identify the correct configuration for your project.

Key Selection Criteria for MS27467 Connectors

When choosing an MS27467 connector, evaluate these core decision points against your application requirements:

• Mating Interface and Coupling: The series uses a bayonet coupling mechanism for quick, secure mating. Confirm the plug and receptacle styles match your panel or cable mounting needs.
• Core Count and Contact Layout: Available in various core counts, the contact arrangement must match your circuit requirements. Verify the pinout and gender (pin or socket) for each part number.
• Electrical Ratings: Check the current and voltage ratings for the specific contact size and configuration. These values are defined per contact and must be derated based on ambient temperature and altitude.
• Environmental Protection: The connectors offer specific Ingress Protection (IP) ratings when mated. Confirm the required IP rating for your application, noting that the rating applies only when the connector is fully mated and locked.
• Termination Method: Options include solder, crimp, or PCB contacts. Select the termination that aligns with your assembly process and serviceability needs.

Material and Construction

The MS27467 series is constructed from corrosion-resistant materials suitable for harsh environments. The shell is typically aluminum with a conductive plating, while insulators are high-temperature thermoset materials. Contact plating is specified to ensure low contact resistance and durability. Verify the specific material and plating options for your chosen part number, as they affect weight, conductivity, and environmental resistance.

Electrical and Environmental Performance

Electrical performance is defined by contact resistance, insulation resistance, and dielectric withstanding voltage. These parameters are tested under controlled conditions. Operating temperature ranges are specified for the connector materials and must be considered alongside the derating curves for current. The waterproof rating, typically IP67 when mated, indicates protection against dust and temporary immersion. Always confirm the tested conditions and derating factors from the manufacturer's datasheet for your specific configuration.

Termination and Installation

Termination options for MS27467 connectors include crimp and solder styles. Crimp terminations require specific tooling for consistent results, while solder terminations offer a simpler field repair option. Proper installation requires attention to backshell selection, cable strain relief, and mating torque to achieve the rated environmental seal. For detailed specifications on types, core counts, and termination, refer to the MS27467 Circular Connectors catalog.

Application Boundaries

This series is suited for applications requiring a rugged, quick-disconnect circular interface. It is not intended for high-speed data transmission or applications requiring a threaded coupling for high-vibration resistance. For those needs, consider other series within the military connector family. If your application involves extreme temperature or specific vibration profiles, verify the connector's performance against your system requirements.

Next Step: Verify Your Configuration

To proceed, confirm your required core count, contact type, mounting style, and termination method. Cross-reference these with the part number system to ensure compatibility.
