Detail Information
M12 K code circular connectors characteristic

Description
- Standards: M12 K Coded Female 4+PE Circular Connector follow specific standards, which allow them to provide higher current carrying capacity. Coded connectors can support voltages up to 800VAC/DC and currents up to 16A per pole for applications requiring high power inputs.
- High-performance materials and design: Manufactured with high-quality materials, including gold-plated contacts and corrosion resistant housings. It not only improves the electrical conductivity, but also extends the service life of the connector and enhances its durability in harsh environments.
- Protection level: IP67 level of protection, can effectively prevent dust from entering and resist underwater immersion in a short time.
- Application scenario: Due to its powerful power transmission capability and rugged design,M12 K Coded Female 4+PE Circular Connector are widely used in servo drives, robotics, and other fields requiring high power input. Ideal for replacing traditional power interfaces, especially when space is limited.
- Installation Flexibility: A variety of shape design options are available, including straight and angular shapes, to suit different installation needs. The most suitable product can be selected according to the specific application scenario, thus simplifying the installation process and improving the overall efficiency of the system.
