M12 D-Code 4-Pin PROFINET Industrial Ethernet Cable
M12 D-coded 4-pin to RJ45 PROFINET Type C Ethernet cable, 100 Mbps Fast Ethernet, Cat5e SF/UTP 24 AWG, IP67 per IEC 61076-2-101, PUR green jacket. For PROFINET controllers, distributed I/O and sensor-actuator networks. Built to length.
Last updated: 7 September 2026
Overview
M12 D-code 4-pin cable assembly wired for PROFINET Type C industrial Ethernet. D-coding is the IEC 61076-2-101 keying for 100 Mbps Fast Ethernet on two twisted pairs. The green PUR jacket and SF/UTP (overall braid + foil) construction match the PROFINET installation guideline for cabinet-to-machine cabling in factory automation.

| Jacket | PUR halogen-free, drag-chain rated, green (PROFINET color) |
Construction and Materials
Two twisted pairs of 24 AWG stranded copper, aluminum-foil pair shielding plus an overall tinned-copper braid giving SF/UTP performance to ISO/IEC 11801 Class D (Cat5e). Characteristic impedance 100 ohm, suitable for 100BASE-TX. The green PUR jacket is oil- and coolant-resistant per EN 50363-10-2 and rated for drag-chain use on request. D-coded 4-pin assignment: pin 1 TX+, pin 2 RX+, pin 3 TX-, pin 4 RX-.
Typical Applications
- PROFINET network drops between PLC, distributed I/O (ET200, ET200AL), field-mounted switches and PROFINET-capable drives; machine-to-machine Ethernet links on automated cells; sensor and actuator networks carrying 100 Mbps real-time traffic; replacement for fixed installation PROFINET Type C cable runs where drag-chain flexing is required.
Compatibility and Fitment
Compatible with PROFINET Type C devices from Siemens, Phoenix Contact, Beckhoff, Wago and other vendors that use the M12 D-coded 4-pin form factor. Not compatible with A-coded sensor sockets, B-coded PROFIBUS, X-coded Cat6A or T/L-coded Power M12 connectors.
Custom Builds and Ordering
Length, connector pin count, coding and jacket material are all configurable. Common builds are listed in the attributes table above; everything else can be specified when requesting a quote. We do not publish a fixed list price because most M12 / M8 assemblies are quoted to a specific build. Lead time depends on length and connector tooling.
Packaging and Shipping
Each cable is individually bagged and labeled with coding, length and lot. Bulk packaging is used for OEM volume orders. Shipments leave our facility within the lead time confirmed on the order acknowledgement.
Quality and Compliance
This product family is designed around the connector codings listed above. The IEC standards referenced (IEC 61076-2-101, IEC 61076-2-109, IEC 61076-2-111, IEC 63171-7, ISO 20653 for IP69K) define the mechanical keying, electrical ratings and sealing performance. Compliance verification (UL, CE, RoHS, REACH) is documented per build on request.
