Whether clients need a stable custom automotive wire harness for vehicle-mounted industrial equipment or a compact d sub cable adapter for cabinet signal switching, our R&D team can adjust wiring layout, shielding structure and connector collocation to match exclusive equipment parameters. All finished assemblies comply with RoHS environmental standards, and each batch of automotive wiring assembly undergoes strict high-voltage insulation and bending durability tests before delivery, serving factory integrators, auto electronic manufacturers and network detection equipment suppliers worldwide.
This Industrial M12 to RJ45 Ethernet Cable 4Pin D Coded Female Adapter is engineered to solve long-distance stable network transmission demands between field industrial sensors and control hosts, standing out from ordinary unshielded network jumpers with its dual-end fully shielded design. The D-coded M12 metal circular plug on one side locks tightly with vehicle-mounted and factory industrial interfaces, effectively resisting vibration, dust and oil pollution in workshop or onboard operation environments, while the shielded RJ45 female terminal on the other end connects directly to industrial switches and data acquisition modules without signal attenuation.

The internal wire adopts CAT5E shielded twisted pair with 24AWG conductors, supporting high-speed EtherCAT and PROFINET bus signal transmission. Its outer PVC jacket withstands temperatures from -40℃ to 105℃, perfectly adapting to the extreme temperature conditions of commercial vehicle chassis and outdoor automation workshops. Every terminal inside the connectors uses nickel-plated brass to maintain low contact resistance, and the built-in copper foil shielding layer eliminates electromagnetic interference generated by surrounding power lines, a critical advantage when matched with any complete automotive wiring assembly for vehicle industrial control systems.
If your project requires multi-channel signal simultaneous transmission or longer wiring distances, we can expand this single Ethernet line into a complete cable set paired with a tailored d sub cable adapter, realizing unified transmission of network signals and power signals inside equipment cabinets. For clients developing vehicle-mounted industrial detection devices, we can further optimize this cable’s structural layout to create a dedicated custom automotive wire harness integrated with power supply branches, simplifying onboard wiring layout and reducing assembly difficulty.
Widely applicable to machine vision cameras, heavy-duty truck industrial monitoring modules, factory automation servo equipment, roadside intelligent sensing devices and offline industrial debugging workstations, this M12 to RJ45 transmission cable balances industrial durability and network transmission stability. Unlike purely vehicle-focused wiring products we supply, this assembly targets cross-scene industrial Ethernet connection, and we offer full customization of cable length, pin definition and connector appearance to fit different brands of automation and vehicle-mounted control equipment.
