The DTECH Industrial Connectivity Range: M12 Connectors, Assemblies & Cable Built for the Factory Floor

Standard office-grade connectors and patch leads aren’t built for what a factory floor, plant room or outdoor cabinet throws at them: vibration, washdown, oil mist, temperature swings and constant flexing. DTECH’s industrial range covers the full connectivity chain for these environments — M12 D-code and X-code connectors, made-to-order M12 and RJ45 assemblies, industrial-grade bulk cable, and the plugs, glands and panel hardware that hold it all together. Everything below is UK-stocked and links straight to the product page.

M12 D-Code: the industrial fieldbus standard

DTECH M12 male metal plug, 4-pin D-code, PG9 screw termination.

M12 D-code is the 4-pin connector you’ll find on the vast majority of industrial Ethernet field devices — sensors, drives, I/O modules and PLC ports running PROFINET, EtherNet/IP or general fast Ethernet. It’s rated to 100Mbps, which matches what the D-code standard and the field devices using it are built for.

The D-code connector range covers every orientation and mounting style you’ll need for a control panel build or field repair:

• M12 Male Metal Plug, 4-Pin D-Code, PG9 (Screw)
• M12 Male Angled Metal Plug, 4-Pin D-Code, PG9 (Screw)
• M12 Female Metal Plug, 4-Pin D-Code, PG9 (Screw)
• M12 Female Angled Metal Plug, 4-Pin D-Code, PG9 (Screw)
• M12 Back Mount Shielded Female, 4-Pin D-Code (Solder / Threaded M16×1.5)
• M12 Front Mount Female, 4-Pin D-Code (Solder / Threaded M16×1.5)
• M12 Front Mount Female, 4-Pin D-Code (PCB / Threaded M16×1.5)
• M12 Female to RJ45 Adaptor, 4-Pin D-Code
• M12 Angled Female to RJ45 Adaptor, 4-Pin D-Code

M12 X-Code: 10Gbps in an IP67 shell

DTECH M12 angled male metal plug, 8-pin X-code, with crimp contacts.

Where D-code stops at 100Mbps, X-code picks up. It’s the 8-pin M12 variant built for full duplex Gigabit and multi-gigabit Ethernet — up to 10Gbps — while keeping the same rugged, twist-lock M12 shell. If a machine vision camera, industrial switch uplink or high-speed I/O backbone needs real bandwidth in a harsh environment, X-code is the connector for the job.

• M12 Angled Male Metal Plug, 8-Pin X-Code /w Contacts, PG9 (Crimp)
• M12 Female Metal Plug, 8-Pin X-Code, PG9 (Solder)
• M12 Angled Female Metal Plug, 8-Pin X-Code, PG9 (Solder)
• M12 Shielded Female Back Mount Socket, 8-Pin X-Code (Solder / Threaded M16×1.5)
• M12 Female Front Mount Socket, 8-Pin X-Code (Solder / Threaded M16×1.5)
• M12 Female Front Mount Socket, 8-Pin X-Code (PCB / Threaded M16×1.5)
• M12 Female to RJ45 Adaptor, 8-Pin X-Code
• M12 Angled Female to RJ45 Adaptor, 8-Pin X-Code

Assemblies: made to order, in any length

DTECH 4-pin D-code M12 PROFINET/EtherCAT assembly — shielded, halogen-free, made to your length.

Connectors on their own solve half the problem — the other half is getting a properly terminated, tested cable between two points. DTECH’s M12 assemblies are manufactured to order in the length you specify, not sold off the shelf in fixed 1m/2m/5m increments, so you get exactly what the panel or machine run needs with no slack to manage and no coupler joints to fail.

M12 X-code assemblies are built on Cat6A S/FTP PUR cable, so every made-to-length lead is rated for the full 10Gbps the X-code connector supports — not downgraded by a lower cable category:

• 8-Pin X-Code M12 Male to Male – Cat6A S/FTP PUR
• 8-Pin X-Code M12 Female to Male – Cat6A S/FTP PUR
• 8-Pin X-Code M12 Female to Female – Cat6A S/FTP PUR
• 8-Pin X-Code M12 Female Angled to Female Angled – Cat6A S/FTP PUR
• 8-Pin X-Code M12 Male Angled to Male Angled – Cat6A S/FTP PUR
• 8-Pin X-Code M12 Male to RJ45 – Cat6A S/FTP PUR
• 8-Pin X-Code M12 Female Angled to RJ45 – Cat6A S/FTP PUR

M12 D-code assemblies are built for PROFINET and EtherCAT panels specifically — shielded and halogen-free as standard, in every straight, angled and RJ45-terminated combination:

• 4-Pin D-Code M12 Male to Male – PROFINET Shielded Assembly, Halogen Free
• 4-Pin D-Code M12 Female to Female – PROFINET Shielded Assembly, Halogen Free
• 4-Pin D-Code M12 Female Angled to Female Angled – PROFINET Shielded Assembly, Halogen Free
• 4-Pin D-Code M12 Male to XG RJ45 – PROFINET Shielded Assembly, Halogen Free
• 4-Pin D-Code M12 Female Angled to XG RJ45 – PROFINET Shielded Assembly, Halogen Free

Both families are available in every mix of straight, angled, male, female and RJ45-terminated ends shown on the range pages — if the exact combination you need isn’t linked above, it’s still available to order.

Industrial RJ45: tool-free, on-site termination

DTECH industrial RJ45 connector, 8-pin, tool-free metal shell.

Not every industrial run can be pre-measured. DTECH’s tool-free industrial RJ45 connectors let you terminate on site in minutes, with a metal shell that survives the environment a standard RJ45 boot never would:

• Industrial RJ45 Connector, 8-Pin, Tool-Free Metal
• Industrial RJ45 Connector, 4-Pin, Tool-Free Metal
• Weatherproof RJ45 Male Plug, ≤8.0mm Cable (Threaded)

Industrial Ethernet leads: industrial or marine cable spec

DTECH’s industrial patch leads are available across Cat5e, Cat6 and Cat6A, each in RJ45-to-RJ45 and RJ45-to-keystone terminations — and each can be specified on either industrial-grade or marine-grade cable, depending on the environment. Both are S/FTP PUR-jacketed for mechanical and chemical resistance; the marine spec adds the additional corrosion and UV resistance needed for salt-air and offshore/dockside installs.

• Cat6A Industrial Ethernet Patch Lead – 8-Pin XG RJ45, S/FTP PUR
• Cat6 Industrial Ethernet Patch Lead – 8-Pin XG RJ45, S/FTP PUR
• Cat5e Industrial Ethernet Patch Lead – 8-Pin XG RJ45, SF/UTP PVC
• Cat6A Industrial Patch Lead – RJ45 to Keystone Jack, S/FTP PUR
• Cat6 Industrial Patch Lead – RJ45 to Keystone Jack, S/FTP PUR
• Cat6A Industrial Patch Lead – Keystone to Keystone, S/FTP PUR

The same industrial/marine choice runs through to bulk cable, for anyone terminating their own runs:

Built for the environment: IP ratings explained

Every connector in the range carries an IP rating, and it’s worth knowing what those digits actually guarantee before specifying a panel or outdoor enclosure:

DTECH’s M12 D-code and X-code connectors are rated IP67 when correctly mated — dust-tight and protected against temporary immersion, which covers the overwhelming majority of factory, outdoor cabinet and machine-mounted applications. Where a spec calls specifically for continuous submersion or high-pressure washdown, check the individual product page for the exact IP68/IP69K rating before specifying.

Plugs, glands & panel hardware

DTECH RJ45 panel mount connector, female-to-female angled, Cat5e 8-pin STP shield.

The connectors and cable get most of the attention, but the small parts are what keep an install weatherproof and serviceable long-term:

• M20 Nylon Cable Entry Strain Relief Boot — protects terminations at panel and enclosure entry points, IP68 rated
• Weatherproof Loose Housing for ≤8.0mm Cable (Threaded)
• Weatherproof Loose Housing for ≤3.0mm Cable (Threaded)
• E13 Protective Dust Cover (Threaded)
• RJ45 Port Industrial Protective Dust Cap
• RJ45 Female to Female Straight, Panel Mount, Cat5e 8-Pin STP Shield
• RJ45 Female to Female Angled, Panel Mount, Cat5e 8-Pin STP Shield

For DIN rail-mounted keystone termination in control cabinets, the range covers stainless steel and ABS adaptors in 1, 2 and 3-port configurations:

• Stainless Steel DIN Rail Keystone Jack Adaptor, 1 Port
• Stainless Steel DIN Rail Keystone Jack Adaptor, 2 Port
• Stainless Steel DIN Rail Keystone Jack Adaptor, 3 Port
• ABS 35mm DIN Rail Keystone Jack Adaptor, 1 Port

Industrial fibre: LC and SC in a rugged housing

Where the run needs fibre rather than copper — longer distances, EMI-heavy plant rooms, or hazardous-area separation — the same panel-mount philosophy carries across to LC and SC connectors in threaded and bayonet industrial housings:

• Fibre Optic LC Duplex, Front Mount (Threaded)
• Fibre Optic LC Duplex, Back Mount (Bayonet)
• Fibre Optic SC Simplex, Front Mount (Threaded)
• Fibre Optic SC Simplex, Back Mount (Bayonet)

Frequently asked questions

What’s the difference between M12 D-code and X-code?

D-code is the 4-pin M12 connector used for 100Mbps fieldbus and sensor connections — PROFINET, EtherNet/IP and general industrial Ethernet at device level. X-code is the 8-pin variant built for full duplex Gigabit and multi-gigabit Ethernet up to 10Gbps, typically used for switch uplinks, cameras and high-speed backbone runs.

Can I get a made-to-length M12 assembly rather than a fixed length?

Yes — both the M12 X-code and M12 D-code assembly ranges are manufactured to the length you specify, in any combination of straight, angled, male, female and RJ45-terminated ends.

What’s the difference between the industrial and marine cable spec on industrial Ethernet leads and bulk cable?

Both are S/FTP PUR-jacketed for mechanical toughness. The marine spec adds the additional corrosion and UV resistance needed for salt-air, coastal and dockside environments; the standard industrial spec covers general factory, plant room and outdoor cabinet use.

What IP rating do DTECH’s M12 connectors carry?

IP67 when correctly mated — dust-tight and protected against temporary immersion. Check individual product pages where a spec calls for IP68 (continuous submersion) or IP69K (high-pressure washdown).
