The HE-016-MS B(17-32) is a heavy-duty male industrial circular connector engineered for high-reliability power and signal transmission in rugged industrial environments. Built with a durable metal housing and rated IP67 for ingress protection, it effectively resists dust, water immersion, and mechanical shock, ensuring consistent operation even in harsh outdoor or factory settings.
It comes with 16 gold-plated male contacts that minimize contact resistance and deliver stable connectivity. The connector supports a rated current of 7A per contact and a rated voltage of 350V AC/DC, with a broad operating temperature range from -40°C to 125°C to adapt to extreme thermal fluctuations.
Featuring a B-type bayonet locking mechanism, it enables tool-free, quick mating and unmating while providing vibration-resistant connections. Its 17–32 wire gauge compatibility makes it ideal for industrial automation lines, power distribution units, and heavy-duty machinery that demand secure, long-lasting multi-channel connectivity.
