The M12-K Coding Board Rear Mount 3PIN(2+PE)Female Socket Plug plate type connector is made of high-quality metal materials with excellent corrosion resistance and durability. Its circular design is compatible with industrial standards to ensure wide applicability. The welding installation method makes the connector firmly fixed, reducing the risk of loosening and disconnection. At the same time, it meets the IP67/IP68 protection level and is suitable for use in harsh environments.
The connector design takes into account parameters such as on-resistance, maximum voltage and current to ensure a stable and reliable electrical connection. The rated current can reach up to 16A, and the rated voltage is suitable for AC and DC applications, with the function of transmitting data signals and power supply. The insulation resistance and contact resistance meet industry standards to ensure good electrical performance.
This connector is widely used in the field of industrial automation, including the connection needs of PLC control systems, sensor networks, robotic systems and other equipment. At the same time, it is also suitable for various industrial scenarios such as manufacturing, logistics warehousing and mechanical processing, providing a reliable solution for stable electrical connection between equipment.
