Shenzhen Fubang Wire Harness Co., Ltd. is a comprehensive OEM & ODM manufacturer that integrates independent mold development, automated cable processing and standardized electrical testing. We focus on the R&D and production of industrial extended wiring and vehicle signal transmission assemblies, delivering stable and reliable wiring solutions to global automation equipment manufacturers, heavy-duty vehicle brands and RV aftermarket suppliers. Our mature production system can flexibly realize customized structural adjustments, enabling us to manufacture high-performance custom automotive wire harness tailored to the long-distance transmission needs of various vehicle-mounted and industrial equipment, with all raw materials complying with RoHS international environmental standards.
This M12 4Pin Male to Female 15M Yellow Waterproof Extension Cable is a long-distance signal extension assembly designed for harsh outdoor and vehicle operation environments, completely different from short-distance conventional jumper wires on the market. Equipped with a pair of threaded locking M12 4Pin male and female aviation connectors with yellow protective sleeves, the cable adopts composite multi-core shielding wire inside, which can stably transmit power and sensor signals over a 15-meter ultra-long distance without signal attenuation. It serves as a durable extension piece of standard car wiring cables, widely used for signal extension between tractor hosts, trailer sensors and outdoor monitoring equipment.

The two ends of the M12 connector are fitted with waterproof silicone sealing rings, and the metal threaded locking structure effectively prevents water, dust and mud from penetrating during long-term vehicle driving and outdoor field work. The internal composite wire is composed of multi-specification tinned copper conductors wrapped with wear-resistant black PVC outer sheath, which can maintain stable electrical performance within the temperature range of -20℃ to +80℃. The complete set of matched automotive cable and connectors ensures tight plugging without loose contact, and we can adjust the total length, wire gauge and pin definition according to customers’ actual installation space to produce exclusive custom automotive wire harness that matches long-distance wiring layout of heavy trucks, agricultural machinery and caravan detection systems.
Every finished extension cable undergoes strict DC 300V withstand voltage test, full continuity inspection and tensile fatigue test before delivery to eliminate hidden dangers such as open circuit, short circuit and poor signal transmission. The injection-molded strain relief at both connector ends strengthens the connection between wire and plug, avoiding core wire breakage caused by vehicle bumping and frequent dragging in daily use. A self-adhesive synthetic label is attached to the cable surface for easy distinction during on-site equipment assembly and maintenance, greatly improving the efficiency of wiring arrangement for construction technicians.
This ultra-long waterproof M12 extension wiring assembly boasts multi-scenario compatibility. It can be used as long-distance signal extension wiring for factory automation sensors, outdoor agricultural machinery power transmission lines, and vehicle-mounted detection equipment connecting cables for heavy trailers and motorhomes. As a special long-distance variant of our full range of car wiring cables, it can be matched with different aviation plugs and terminal accessories to expand multi-channel signal transmission kits. It also forms complete supporting wiring kits with assorted automotive cable and connectors, and our engineering team can optimize the wire shielding structure to develop more targeted custom automotive wire harness for customers with ultra-long distance transmission demands.
