“2PNCT is a Japanese-standard rubber cable for domestic equipment, while SO is a UL-certified flexible rubber cord designed for North American industrial use.”
2PNCT (JIS) A Japanese-standard rubber cable used mainly in domestic industrial equipment. Durable and weather-resistant, but not UL-certified, so it cannot be used in North American installations requiring UL/CSA compliance.
SO Cable (UL/CSA) A flexible, heat- and oil-resistant rubber cord widely used in North America. Ideal for machinery, robotics, and temporary power. Fully compliant with UL/CSA, making it suitable for export and OEM equipment.
