YMB18T7Z1P1 Corrosion and Waterproof Circular Electrical Connector, designed for a tight waterproof fit, the head housing and socket feature fine threads to prevent loosening, and it contains two layers of waterproof seals. As the housing threads are tightened, the seal becomes more effective. The plug's tail is aluminum-coated, fully enclosed with the cable, formed in one piece for waterproof and tensile resistance. This series of aviation connectors is used for equipment and cable connections in harsh environments such as moisture and immersion. It can achieve a waterproof seal at depths of up to 50 meters underwater, and operates normally on the basis of ship movement. It is the preferred product for ships, offering waterproof and corrosion-resistant properties at an affordable price. The line spring pins provide smooth insertion and removal, have low resistance during contact, excellent shielding, noise-free transmission, and are particularly suitable for signal transmission.
