With in-house production capabilities covering precision wire cutting, terminal crimping, circular connector overmolding, waterproof sealing treatment and comprehensive electrical testing, the company delivers reliable connection products to global clients in automotive, industrial automation, outdoor equipment and electronic manufacturing sectors. Its product portfolio covers various auto cables and accessories, professional car wire harness solutions and diverse automotive cable assembly products for passenger vehicles, commercial vehicles and industrial electronic equipment, all fully complying with RoHS environmental standards and strict quality inspection procedures.
This M11 8Pin female to male extension cable is a compact waterproof signal transmission harness designed for short-distance connection between industrial sensors, outdoor electronic modules and vehicle on-board devices. Different from long OBD2 diagnostic cables and multi-branch data transmission harnesses, this product focuses on a concise straight-through extension architecture with a total length of just 77±10mm, making it ideal for confined installation spaces where long cables would cause unnecessary clutter, interference or installation difficulty. One end features an M11 8Pin female connector with front-panel keyed core for secure orientation, while the other end is fitted with an M11 8Pin male connector with threaded locking nut and waterproof rubber ring, providing reliable IP-rated sealing and vibration-resistant connection for outdoor and industrial environments.

The internal conductor adopts UL2464 certified 20AWG 6-core shielded cable with black semi-matte PVC outer jacket, integrating aluminum foil shielding layer to suppress electromagnetic interference and ensure stable signal transmission in electrically noisy industrial and vehicle environments. The cable is rated for operation between -40℃ and +80℃, adapting to severe temperature fluctuations in outdoor equipment housings and vehicle engine compartments. Each conductor is color-coded (black, brown, red, orange, blue, green) for clear pin function identification, and a printed number tube is pre-attached on the cable body for quick model recognition and installation sorting. The connector transition points are reinforced with heat shrink tubes for strain relief and additional sealing, preventing wire breakage and moisture intrusion at the most vulnerable stress points.
Every finished cable undergoes strict 100% electrical testing before delivery, including full continuity inspection, DC 300V withstand voltage test, insulation resistance measurement and conduction resistance verification to eliminate open circuits, short circuits and pin misalignment. Insulation resistance is maintained above 10MΩ while maximum conduction resistance is controlled within 2Ω, ensuring stable and low-loss signal transmission across all connected channels. The keyed orientation feature ensures correct mating alignment every time, preventing pin damage from incorrect insertion. All raw materials fully comply with RoHS environmental requirements, and connector housings are visually inspected for cracks, deformation and surface defects before shipment. The product is individually packaged in PE bags for convenient storage and transit protection.
This M11 waterproof extension cable is widely applied in industrial sensor connection, outdoor monitoring equipment wiring, vehicle on-board sensor signal extension, construction machinery electronic control, marine instrument connection, agricultural equipment wiring and harsh-environment industrial control projects. It serves as a reliable short-distance signal extension medium for installers and technicians requiring secure, waterproof connection in confined spaces. For projects requiring adjustable cable length, different pin counts, custom connector types or enhanced shielding structures, the engineering team can develop exclusive solutions using tailored automotive cable assembly technology to match specific equipment configurations. The company continuously optimizes the waterproof sealing performance and mechanical durability of every product in its car wire harness lineup, and its comprehensive auto cables and accessories portfolio supports various custom interconnection projects for industrial and automotive applications.
