M16 2-8 Pin Circular Connectors IP67 Waterproof Screw Locking

LD20/SP20 Industrial Flange Connector Dimensions and Specs

The M16 connector is a rugged, high-performance circular connector designed for reliable power and signal transmission in demanding industrial and outdoor environments. Built with precision-engineered contacts and a robust housing, it delivers excellent mechanical strength, vibration resistance, and long-term durability.

M16 Connector Selection and Configuration

When selecting an M16 connector, the first decision is the number of cores. This series is available in 2 to 8 pin configurations, supporting both male and female genders. The housing is machined from brass with nickel plating, while the contacts are brass plated with silver or gold, depending on the electrical and environmental requirements of your application.

Application Fit and Environmental Protection

With an IP67–IP68 waterproof rating, the M16 connector provides dependable protection against dust, moisture, and temporary water immersion, making it ideal for outdoor LED lighting, solar power systems, industrial automation, sensors, robotics, and marine applications. The threaded M16 locking mechanism ensures a secure and stable connection, preventing accidental disconnection even under heavy vibration.

Electrical Performance and Reliability

Featuring high dielectric strength withstanding up to 1,000–1,500V test voltage, ultra-high insulation resistance (≥ 5,000 MΩ), and low contact resistance (≤ 40 mΩ), the M16 connector ensures efficient, safe, and stable electrical performance over time. The durable PA66 or metal housing offers superior heat resistance, corrosion protection, and mechanical reliability.

Installation and Mating Considerations

Before ordering, confirm the mating-side requirement, pinout or drawing, cable outside diameter, conductor size, and electrical load. These details are essential for matching the correct plug and socket combination. For related flange-mount options, review the LD20/SP20 Industrial Flange Connector Dimensions and Specs.
