M16 3 Core Panel Mount Threaded Waterproof Connector IP67

The M16 3‑core panel‑mount threaded connector is a high‑current bulkhead interface for industrial power distribution, motor controls, and heavy‑duty outdoor equipment – rated 20A/250V AC, the highest in the M16 series. The M16×1.0 thread provides secure locking under vibration. Electrical performance: contact resistance ≤10mΩ, insulation ≥500MΩ at DC 500V, dielectric withstand 1.5kV AC, stable after 1,500 mating cycles. IP67 sealing with nickel‑plated brass pins and PVC housing ensures operation from –20°C to +85°C. Mounts through a panel cutout with threaded bushing and sealing washer – no cable pass‑through, reducing moisture ingress. Parallel circuit supports flexible wiring. Custom configurations available for OEM projects.

Core Configuration Diagram

Dimensional Drawing

The dimensional drawing provides key mechanical data per attached CAD extract. Male panel‑mount plug: overall length 24.3mm (with nut), mating thread length 12.5mm, coupling nut width 25.7mm across flats. Female receptacle: mating thread depth 14.8mm, seal compression zone 6.6mm. Both use M16×1.0 threads. The core configuration chart indicates for this 3‑pin version: 20A/250V (2‑pin also 20A/250V). Custom pin configurations and mechanical dimensions are available – we can tailor housing length, thread profile, nut size, and contact arrangement to match your specific panel thickness and cable requirements. Tolerances per ISO 2768‑m. PDF/DWG available for CAD integration.

Circular Connector Ring

This photo shows the circular connector ring accessory. The ring provides additional mechanical support and alignment during mating, ensuring proper engagement of the M16×1.0 threads. The black PVC finish matches the connector housing for a consistent appearance and corrosion resistance.

Threaded Interface (Black PVC)

This photo shows the threaded mating interface with black PVC housing. The M16×1.0 external thread and the internal thread profile are clearly visible. The black PVC material provides robust insulation and corrosion resistance for industrial environments.
