A factory-grade M12 cable assembly is more than a connector and a cable
The right M12 cable assembly survives 15 years of vibration, washdown chemicals and drag-chain bending — without ever being the reason your line stops. We build every M12 cable assembly as a complete engineering deliverable: the connector coding (A, B, D, T or X) matches the bus you actually run, the cable jacket is rated for the chemistry your plant uses, the overmold geometry clears the bracket your CAD shows, and the assembly carries a serial number traceable to the spool of wire it came from. That is the difference between a cable that ships and a cable that survives a PPAP audit.
D-coded vs. X-coded vs. A-coded — pick the right one and we will build it
A D-coded M12 cable assembly is the workhorse of Fast Ethernet — 100 Mbit/s Profinet, EtherNet/IP, Modbus TCP — and remains the most-shipped variant in industrial automation. When the protocol moves to 1 Gbit/s or 10 Gbit/s (machine vision, GigE Vision, robotics teach pendants), the X-coded M12 cable assembly is the only IEC-61076-2-109 variant rated for it. A-coded handles power and IO-Link sensors; B-coded covers legacy Profibus; T-coded is the new high-current power variant up to 12 A. Send us the bus, the current and the IP rating — we ship the right coding the first time.
In-house capabilities
Engineering-to-shipping under one roof
DFM, prototyping, PPAP, 100% electrical test — no subcontracted assembly, no black-box outsourcing. Your program stays inside the same IPC/WHMA-A-620 Class 3 lines.
D-coded & X-coded Ethernet
D-coded for 100 Mbit/s Profinet & EtherNet/IP; X-coded for 1/10 Gbit/s GigE Vision and Cat 6a — full IEC 61076-2-109 compliance with TIA-568 channel tests.
A/B/T-coded power & signal
A-coded for sensor + IO-Link, B-coded for Profibus DP, T-coded for 12 A power distribution. Pin counts 3, 4, 5, 8 and 12 — male/female/right-angle/straight.
IO-Link & Profinet stacks
PUR-jacketed IO-Link masters and IO-Link Class A/B devices. We crimp, twist and overmold to keep the differential pair impedance inside the SDCI spec.
IP67 / IP68 overmolding
In-house PUR and TPU overmolding tooling for IP67 (continuous) and IP68 (submerged) ratings. Drop-test, dust-chamber and washdown validation on request.
Drag-chain & continuous-flex
5-million-cycle drag-chain rating verified on robot dress packs and gantry axes. PUR jackets with TPE strain relief, tested per IEC 61156-6 flex cycles.
100% Cirris / DIT-MCO test
Every M12 assembly runs through Cirris or DIT-MCO fixtures — continuity, hi-pot to 500 VDC, insulation resistance and (for X-coded) full TDR + return loss.

Why OEMs choose us
17 years building for engineers who don't accept “close enough”
- Engineer-to-engineer. Every quote routes through a harness engineer, not a sales rep. Your DFM feedback comes from someone who has built the variant — bus protocol, IP rating, drag-chain or static run.
- No black-box assembly. Your M12 cable assembly stays inside our IATF 16949 lines — we do not farm assembly to third parties. Every operator is IPC/WHMA-A-620 Class 3 certified.
- PPAP-level documentation on automotive and Tier-1 industrial programs by default, FAI on every NPI build, traceable BOM down to the wire spool lot codes and connector batch.
- Cirris / DIT-MCO 100% test. Every assembly — prototype or production — runs through full continuity, hi-pot and insulation resistance tests. X-coded variants get TDR and return-loss reports.

FAQ
Common questions before placing your first order
What is an M12 cable assembly and where is it used?
An M12 cable assembly is a sealed industrial interconnect using a 12 mm threaded screw-lock connector. It is the dominant connector for factory-floor sensors, actuators, vision cameras, IO-Link devices and Industrial Ethernet (Profinet, EtherNet/IP, EtherCAT). The threaded coupling holds vibration immunity to IEC 60068-2-6, and the overmolded jacket reaches IP67 or IP68 sealing for washdown and dusty environments.
Can you build D-coded, X-coded, A-coded and T-coded variants?
Yes. We stock A-coded (sensor / IO-Link, 3–5 pins), B-coded (Profibus DP), D-coded (100 Mbit/s Industrial Ethernet, 4 pins), X-coded (1/10 Gbit/s Cat 6a, 8 pins) and T-coded (12 A power, 4 pins). Pin counts 3, 4, 5, 8 and 12 are all supported. Male, female, straight, right-angle and field-attachable variants ship from the same line.
What is the minimum order quantity?
None. We build single-unit prototypes for validation and pilot batches of 10–50 cables while you qualify the design. Production scales from a few hundred to 50,000+ M12 cable assemblies per month on the same overmold tooling — no MOQ penalty.
How fast can you ship a prototype?
Standard prototypes ship in 48 hours from a signed-off drawing or BOM. M12 assemblies that require custom overmold tooling typically take 5–7 working days for the first article. Production lead time is 1–5 weeks depending on connector lead time from Phoenix Contact, TE, Murr or our own stocked inserts.
What IP rating can you guarantee on the overmold?
Standard offering is IP67 (1 m water immersion, 30 minutes) on PUR overmold with TPE strain relief. IP68 (continuous submersion to 5 m) is available with double-shot PUR and is validated per IEC 60529 in our own dust and water chamber. IP69K (high-pressure washdown) is offered on request with PUR-jacket and EPDM seal.
Can you provide testing reports for X-coded Gigabit Ethernet?
Yes. Every X-coded M12 cable assembly ships with a Cirris or DIT-MCO test report covering continuity, hi-pot (500 VDC) and insulation resistance. On request we add TIA-568 channel tests, TDR impedance plots and return-loss curves so your integrator can drop the assembly into a 1000BASE-T1 or 10GBASE-T network without rework.
