Dimensional Drawing

The engineering drawing includes overall length, panel cutout dimensions (diameter and depth), quick-lock sleeve stroke, and pin-1 marking. Cross-sections show the cam mechanism and release travel – hand-tight only, no tools. Max cable OD 4.5mm, tolerances per ISO 2768-m. PDF/DWG files available for CAD.

Product detail

Mating Interface

The detail photo shows two yellow housings during mating, with sleeve partially turned. It demonstrates thumb-operated locking, anti-reverse keyway, and seal compression. An audible click confirms full engagement, reducing misassembly. Useful for installation hand position and rotation direction

Male Plug

This close-up shows the yellow male plug alone. Features include the knurled quick‑lock sleeve, two nickel‑plated brass pins, the rubber O‑ring behind the mating face, and a polarizing key to prevent reverse insertion. The cable entry boot is visible, accepting OD up to 4.5mm.

FAQ

Q1: What is the difference between threaded, quick-latch, and self-locking coupling?

A: Simply put – threaded is the most stable, suitable for high-vibration environments like automotive or industrial machinery. Quick-latch is convenient for frequent mating/unmating, perfect for test equipment. Self-locking requires no tools and works in confined spaces where hands can't reach easily. The choice depends entirely on your actual application scenario.

Q2: What is the difference between male and female connectors?

A: Male connectors have pins (protruding contacts), while female connectors have sockets (recessed contacts). They are designed to mate together – male plugs into female. We offer both types and can provide complete matching sets.
