M12 D-Coded Industrial Ethernet PUR Cable
M12 D-Coded Male to Female | Cat5e | PROFINET Type C | PUR | Drag Chain

The M12 D-Coded male to female Ethernet cable provides a secure Industrial Ethernet connection for factory automation, industrial machinery, machine vision, robotics and compatible PROFINET networks. The assembly combines a straight 4-pin M12 D-coded male plug with a straight M12 D-coded female jack for reliable device-to-device Ethernet connectivity.
Built with shielded Cat5e PUR cable, this M12 D-coded Ethernet cable is engineered for demanding industrial environments involving continuous movement, repeated bending, vibration and abrasion. Its flexible construction makes the cable suitable for drag chain systems with up to 3 million bending cycles according to the supplied cable specification.
Designed for PROFINET Type C applications, the M12 D-coded PUR cable offers resistance to oil, UV, ozone, hydrolysis, abrasion, seawater, microbes, acids and alkalis. Standard cable lengths are 1 m, 2 m, 5 m and 10 m, while custom M12 cable lengths are available for OEM machinery and industrial automation projects.

Pin Assignment & Wiring
M12 D-Coded 4-Pin Male to Female
According to the supplied wiring drawing, the M12 plug and M12 jack use a straight-through pin configuration. Each conductor connects to the corresponding pin number at the opposite connector.
| Male Pin | Wire Color | Female Pin | Connection |
| Pin 1 | Yellow | Pin 1 | 1 → 1 |
| Pin 2 | White | Pin 2 | 2 → 2 |
| Pin 3 | Orange | Pin 3 | 3 → 3 |
| Pin 4 | Blue | Pin 4 | 4 → 4 |
The straight-through wiring provides a direct connection between compatible M12 D-coded Industrial Ethernet interfaces. The mating interface and pin assignment of the target equipment should always be confirmed before installation.
Mating & Compatibility
M12 D-Coded Industrial Ethernet Interfaces
This M12 D-coded male to female cable is intended for equipment using compatible 4-pin M12 D-coded Ethernet interfaces. The male plug can mate with a compatible female device interface, while the female cable connector accepts a compatible M12 D-coded male plug.
