The waterproof M12 connecting line / connector uses the signal power transmission connection of LED wiring technology, and the intelligent control LED harness system integrates more and more interconnected equipment, including sensors, brakes, actuators, etc. These devices need to have stable and reliable connection lines to provide power and signal transmission, and need to work in a complex environment, so they need waterproof, dustproof and corrosion-resistant functions. M12 connection line is developing rapidly under the growing demand. M12 connecting line can be divided into welding line type and locking terminal type according to the connection mode; assembly type, forming type and panel type according to the assembly mode; a code, B code, C code, D code, P code, s code, t code and X code according to the anti insertion error coding mode; M12 180 degree straight connecting line, M12 90 degree elbow connecting line, M12 t-connecting line and M12 y-connecting line according to the shape. Line. At the same time, there are two types of shielding and unshielded. According to the number of stitches or cores, there are 3pin, 4Pin, 5pin, 8pin, 12 or 3 cores, 4 cores, 5 cores, 8 cores and 12 cores. The outer materials of the connecting wires are pur, TPE, PVC, etc. The M12 connecting wires of jh-com are RoHS, CE, UL certified, with good quality, affordable price and short delivery time.
