Threaded and self-locking waterproof connectors can both support reliable industrial connections, but they suit different installation and operating needs. Choosing between them should be based on the application, mating process, available space, cable routing and service expectations rather than on one feature alone.
When a threaded connector is a practical choice
A threaded connector uses a deliberate mechanical engagement process. This approach can be useful where the installer needs a clear, controlled connection method and the equipment provides enough space for mating and tightening. The CONNIXTECH catalogue includes threaded waterproof connector families in M12, M16, M20 and M25 sizes for industrial automation applications.
When a self-locking connector is a practical choice
A self-locking connector can be considered where the application benefits from a faster, guided mating process. CONNIXTECH lists self-locking families in M16, M20 and M25 sizes, including configurations for industrial and outdoor use. The final choice should take account of connection frequency, user handling, vibration exposure and required circuits.
Compare the complete installation
Connector selection should include the full assembly. Review shell size, pin arrangement, cable direction, panel installation, seal position and service access. A connection method that is convenient in a prototype may need adjustment when used in volume production or field service.
Choose based on the system, not only the connector
For industrial automation, outdoor equipment and e-mobility systems, the practical choice depends on how the connection is used in the finished product. Browse the Product Centre or contact CONNIXTECH for a project discussion.
