Application fit

Is M12 D-coded / X-coded right for your machine?

Engineered for vibration-proof machine-level PROFINET/EtherCAT fieldbus, GigE machine-vision cameras, and EN 50155 rolling-stock backbones.

Energy chain / drag chain

Suitable

PROFINET Type C 7-strand/19-strand tinned copper core and PUR-HF jacket pass 3–5 million drag-chain cycles.

Switchgear & control cabinet wiring

Suitable

M12-to-RJ45 transition cordsets bridge IP67 field switches/cameras directly to IP20 cabinet PLC ports.

Fixed installation

Suitable

EN 45545-2 HL3 cross-linked RADOX/EM104 variants serve onboard railway passenger information and CCTV networks.

Motorised monospiral reel

Not suitable

Pre-terminated M12 patch cords are intended for machine/bogie links rather than long crane supply drums.

Construction

Layer by layer

D-coded uses PROFINET 1×4×22 AWG SF/UTP star-quad; X-coded uses 4×2×26/7 AWG S/FTP with an internal die-cast X-shaped pair separator inside the M12 shell.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

When should I choose M12 D-coded versus M12 X-coded Industrial Ethernet assemblies?
Use 4-pin M12 D-coded (IEC 61076-2-101, Cat 5e) for 100 Mbps deterministic real-time fieldbuses such as PROFINET RT/IRT, EtherCAT, and EtherNet/IP that only require two twisted pairs (TX+ / TX- / RX+ / RX-). Use 8-pin M12 X-coded (IEC 61076-2-109, Cat 6A) when you need 1 Gbps or 10 Gbps bandwidth (GigE vision cameras, LiDAR, train backbone switches) or 4-pair PoE+/PoE++ power delivery.
How does the M12 X-coded connector achieve Cat 6A (500 MHz) performance inside a 12 mm shell?
Inside the M12 X-coded connector body, a precision die-cast metal X-shaped cross-shield physically isolates each of the four differential pairs right up to the contact PCB/crimp zone, suppressing near-end cross-talk (NEXT) and alien cross-talk up to 500 MHz.
What is the pin mapping on an M12 D-coded to RJ45 transition cable?
Standard PROFINET M12 D-coded to RJ45 patch cords wire M12 Pin 1 (TD+, Yellow) to RJ45 Pin 1, M12 Pin 2 (RD+, White) to RJ45 Pin 3, M12 Pin 3 (TD-, Orange) to RJ45 Pin 2, and M12 Pin 4 (RD-, Blue) to RJ45 Pin 6, with 360° shield continuity between both connector shells.
Are EN 50155 / EN 45545-2 HL3 railway versions available?
Yes. Specify the -RAIL suffix (e.g., M12D-MM-5M-RAIL or M12X-MM-10M-RAIL) to substitute the industrial green PUR jacket with an electron-beam cross-linked halogen-free RADOX/EM104 railway jacket certified to EN 45545-2 Hazard Level 3 (HL3) and EN 61373 bogie/carbody vibration.
