Phoenix 1408609 — D-coded industrial Ethernet

Connect a documented 100Mb/s PROFINET/EtherCAT industrial endpoint with a D-coded M12 interface to its specified RJ45 path.

Also called Phoenix Contact 1408609 configured NBC-M12FRD-R4QC-PN/.../...; opened 93B cable option

A shared M12 shell does not make D and X coding interchangeable; headline enclosure wording may omit mating conditions.

The useful distinction

Match the complete manufacturer identity, endpoint roles and selected length; a similar shell or cable color is insufficient.

Bounded facts, visible unknowns

Specifications and limits

Phoenix 1408609 — D-coded industrial Ethernet facts and limitations
Documented task / modePROFINET/EtherCAT CAT5, 100Mb/s for this configured family and option; not an X-coded 10Gb/s assembly. [C985A]
Construction / lengthOpened option 93B uses shielded PVC stranded star-quad copper, 1×4×AWG22/7; exact selected cable option matters. The opened page offers 0.2–85m configurable length for its displayed option; an earlier search extract said 100m. Select an exact configured part and current sheet before procurement. [C985A]
Verified device listNot included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.

Opened option 93B uses shielded PVC stranded star-quad copper, 1×4×AWG22/7; exact selected cable option matters. M12 technical data lists IP65/IP67, while the RJ45 technical data says IP20 despite headline IP67 wording. Treat the exposed RJ45 environmental scope as unresolved; no wet-location recommendation.

Before you connect

What to check

  1. Resolve RJ45 enclosure/protection with Phoenix for the exact assembly; obtain the generated configuration sheet and endpoint manuals.
  2. Check condition with power disconnected where the equipment guidance permits; stop for damage, heat or unknown powered connections.
  3. Keep published source support separate from physical test results.

Direction and fallback

Industrial Ethernet data is two-way; socket and plug roles describe the connector, not one-way signal flow. A four-position D-coded path does not become four-pair gigabit copper by changing the RJ45 end.

Worked selection example

For a documented D-coded 100Mb/s controller path, choose the configured cable option and length; check the actual RJ45 enclosure and mate before considering environmental suitability.

What to observe next

Resolve RJ45 enclosure/protection with Phoenix for the exact assembly; obtain the generated configuration sheet and endpoint manuals.
