M Series Circular Connectors: A Catalog for Application-Driven Selection

Selecting the right circular connector for industrial equipment requires matching mechanical, environmental, and electrical specifications to your specific application. This catalog organizes M series connectors by type, core count, and full specifications, enabling you to identify a component that aligns with your system's requirements. The following guide explains how to use the catalog structure to make an informed decision.

Understanding the M Series Connector Range

The M series encompasses a broad family of circular connectors differentiated by shell size, contact arrangement, and performance characteristics. The catalog groups these connectors by type and core count, allowing you to narrow your search based on the physical interface and the number of circuits required. Review the specifications for each series to understand the electrical limits, environmental protection, and termination methods available.

Key Selection Criteria for Your Application

When evaluating M series connectors, focus on the following parameters to ensure a proper fit for your equipment:

• Electrical ratings: Verify the current and voltage ratings for each contact size and arrangement. Consider derating factors based on ambient temperature and altitude as specified in the catalog.
• Environmental protection: Check the IP rating for resistance to dust and water ingress. Confirm whether the rating applies only when mated and locked, as is typical for circular connectors.
• Mechanical durability: Review the mating cycle life and the mechanical locking mechanism to ensure it withstands your application's vibration and plugging frequency.
• Termination and mounting: Select between solder, crimp, or PCB contacts, and choose the appropriate cable entry or panel mounting style for your installation.

Interpreting the Catalog Specifications

The catalog provides detailed tables with rated values and test conditions. Pay attention to the distinction between the maximum rated current and the current carrying capacity under specific operating conditions. Similarly, the insulation resistance and contact resistance values are measured under controlled laboratory conditions; your application's actual performance may vary based on cable length, temperature, and installation quality.

Next Steps for Component Selection

Use the catalog's type and core count filters to create a shortlist of compatible M series connectors. Then, compare the detailed specifications against your application's requirements.
