The 16A/3P-637a IP67 40V–50V Low Voltage Industrial Plug is a three-pole connector designed according to the IEC 60309 international standard. Operating within the 40–50V SELV (Safety Extra Low Voltage) range, it provides enhanced electrical safety and stable low-voltage power distribution.
With its IP67 waterproof and dustproof rating, the plug is built for harsh outdoor conditions, temporary immersion, and environments with high moisture or dust exposure.
Its flame-retardant PA6 housing ensures excellent durability, while nickel-plated copper pins deliver superior conductivity and corrosion resistance.
The grey color coding follows IEC 60309 standards for 40–50V low-voltage identification.
