M12 Aviation Plug, Waterproof Connector, 4-core With Wire, Docking Sensor

M12 sensor cable is a common circular connector cable in the field of industrial automation. Due to its durability and stable connection, it is often likened to a "sturdy nerve" between devices, mainly responsible for transmitting power and control signals to sensors, actuators (such as photoelectric switches, cylinder valve islands) and other devices. The following table summarizes its core features for your quick understanding: Specific description of characteristic dimensions The core structure adopts a spiral locking threaded connection (M12 × 1) with a sealing ring to provide stable connection and protection. Internally, there are A code defined pins dedicated to analog/digital signals and low-voltage power supply for sensors/actuators. The number of cores and configurations commonly include 3-core, 4-core, 8-core, 12 core, etc., to meet the power, signal, and bidirectional communication needs of different devices. The protection level generally has IP65, IP67 levels, and some can reach IP68/IP69K, which can prevent dust, water, and temporary immersion, and adapt to harsh working conditions. Many models come with integrated shielding layers, which can effectively resist electromagnetic interference (EMI) and ensure the purity and stability of signals in noisy industrial environments. The sheath material is commonly PUR (polyurethane) or PVC (polyvinyl chloride). PUR is more resistant to oil, wear, hydrolysis, and chemicals; PVC is economical and suitable for dry environments with low requirements. The rated voltage of electrical characteristics is usually ≤ 300 V, and the current carrying capacity varies depending on the number of cores, commonly including 4 A or 1.5 A.
