Dimensional Drawing

The drawing shows overall length, M8×1.0 thread profile, panel cutout and depth, plus polarising key location. Sectional views indicate thread engagement and O‑ring compression for IP67 sealing. Pin‑out diagram marks pin‑1 and contact order. Tolerances per ISO 2768‑m. Available in PDF or DWG for CAD. Check cutout clearance and thread fit before layout, especially for multiple connectors.

Product detail

Male and Female Connectors Side by Side

This photo shows the male plug (left) and female receptacle (right) side‑by‑side. The threaded nut, mating thread, and sealing ring behind the male thread are visible. Size differences are clear – helpful for cabinet clearance planning. Colour contrast (green male, black female) aids field identification. Both cable boots accept up to 4.5 mm OD.

Male Plug Close‑up (Green Interface, 5‑Pin)

This close‑up shows the male plug with green mating face, revealing five contacts in standard M8 circular layout – a 5‑pin variant, but thread size, sealing, and envelope match our 3‑pin model. Nickel‑plated pins and recessed O‑ring are visible. Knurled nut allows tool‑free tightening. Polarising key prevents mis‑insertion. Use this photo to check pin condition and seal integrity before assembly.

FAQ

Q1: What does IP67 waterproof rating actually mean in practice?

A: IP67 means fully dust-tight and capable of withstanding temporary immersion – up to 1 meter for 30 minutes. This applies to outdoor lighting, industrial equipment, marine applications, or any environment exposed to rain, moisture, or occasional submersion.

Q2: What is the difference between IP67 and IP68?

A: IP67 protects against temporary immersion – 1 meter for 30 minutes. IP68 is a higher level – it supports continuous submersion beyond 1 meter. If your application involves underwater lighting or marine equipment that requires long-term immersion, IP68 is the way to go.
