M16 3 Pin Threaded Waterproof Connector IP67

The M16 3‑pin threaded connector sits right in the sweet spot for LED lighting, motor drives, and outdoor distribution gear that runs on 8A/250V. The M16×1.0 thread bites hard against vibration – we've seen these hold up well on pump skids, conveyor lines, and channel letter signs. Electrically, you're looking at ≤10mΩ contact resistance, ≥500MΩ insulation at DC 500V, and 1.5kV dielectric withstand – all validated over 1,500 plug/unplug cycles. IP67 rating with nickel‑plated brass pins and PVC jacket means it handles -20°C to +85°C without complaint, and accepts cable up to 8.0mm OD. Parallel circuit makes daisy‑chaining straightforward. If you need different pinouts, longer leads, or a tweaked housing, we can do that too. It's a solid, no‑nonsense connector for everyday industrial power jobs.

Dimensional Drawing

Key callouts from the CAD: male plug runs 42.6mm overall, with 12.8mm of mating thread and 14.0mm on the panel side – coupling nut flats measure 19.18mm. Female side: 41.2mm overall, thread depth 18.5mm, mounting section 16.2mm. Both use M16×1.0. Current derating for this 3‑pin version is 8A/250V – for reference, 2‑pin does 10A, 4‑pin drops to 6A, 5‑pin 4A, 6‑pin 3A. Tolerances follow ISO 2768‑m. We can supply PDF or DWG if you need to drop it straight into your CAD. And if your cable gland or panel cutout calls for something off‑spec – housing length, thread profile, contact pitch – we can adjust.

Product detail

Male and Female Side‑by‑Side (5‑Pin Version)

This photo shows the male plug and female receptacle of the 5‑pin variant (for illustration purposes) placed side‑by‑side for direct visual comparison. The five nickel‑plated brass contacts are clearly visible on both halves. Both share the same black PVC housing and M16 thread profile. This image helps verify contact alignment and orientation before assembly.

Male and Female at 45°Angle

This 45° angled view shows the male plug and female receptacle separated at an angle, revealing both M16×1.0 metal threads – male external and female internal, both nickel‑plated brass. The black PVC housings and the sealing O‑ring on the male thread root are clearly visible. This image aids in inspecting thread condition and seal position before mating.
