Push-Pull Self-Locking vs. M-Series Connectors: 4 Dimensions for Quick Selection

Push-Pull Self-Locking vs. M-Series Connectors: 4 Dimensions for Quick Selection

1. Comparison of Installation Convenience

◦ Push-Pull Self-Locking Connectors: Adopt a "push-pull" operation mode without rotation, enabling plugging and unplugging within 3 seconds. They operate flexibly in narrow spaces (such as dense wiring areas inside equipment) and are suitable for scenarios requiring frequent assembly and disassembly (e.g., medical testing equipment, stage lighting modules).

◦ M-Series Connectors: Mostly feature a threaded locking design, which requires 3-5 rotations to fix. They operate stably in spacious spaces but tend to have the issue of "being hard to twist" in narrow environments, making them more suitable for long-term fixed connections (e.g., fixed wiring of industrial equipment).

1. Differences in Vibration Resistance

◦ Push-Pull Self-Locking Connectors: Fixed by a latch structure, they can remain stable under normal vibration (such as slight vibration of office equipment). However, there is a risk of latch disengagement under extreme vibration (e.g., automobile engine compartments, large machine tools).

◦ M-Series Connectors: With deep thread engagement and high mechanical strength, they can withstand continuous strong vibration (vibration frequency: 50-2000Hz) and offer better reliability in high-frequency vibration scenarios such as industrial automation production lines and engineering machinery.

1. Distinctions in Sealing Performance

◦ Push-Pull Self-Locking Connectors: Mainstream products can reach an IP67 protection rating (protection against short-term immersion), and some high-end models can achieve IP68. Nevertheless, their sealing life is relatively short in environments with long-term immersion or high-pressure flushing.

◦ M-Series Connectors: Most models have a default IP67 rating, and some industrial-grade products support IP69K (protection against high-pressure and high-temperature flushing). They perform better in humid/watery scenarios such as food processing equipment (requiring frequent flushing) and outdoor water conservancy monitoring instruments.

1. Recommendations for Application Scenario Adaptation

◦ Priority for Push-Pull Self-Locking Connectors: Scenarios with frequent plugging/unplugging, limited space, and normal environments (e.g., medical equipment modules, small electronic instruments, temporary wiring for exhibitions).

◦ Priority for M-Series Connectors: Scenarios requiring long-term fixation, strong vibration resistance, and high sealing performance (e.g., industrial automation equipment, automotive electronic control systems, outdoor heavy machinery).
