- Cable spec — gauge, conductor count, jacket material, shielding
- Drag-chain bend radius (minimum dynamic radius in mm)
- Cycle-life requirement (target flex cycles + axis of bend)
- Connector spec — series, contact count, gender, IP rating
A robotics cable assembly is not the same as an industrial control cable. The cable inside a six-axis robot arm flexes, twists, and torsions millions of times across its service life. Choose the wrong conductor stranding or jacket material and the harness fails inside the warranty window — usually with the robot live on a customer line. We build robotics cable assembly for OEMs who have already learned that lesson once and don't intend to relearn it.
Every robotics cable assembly we ship is built on an IPC/WHMA-A-620 Class 3 line. Class 3 is the highest acceptability standard the IPC publishes and is required by procurement teams in medical, aerospace and Tier-1 automotive robotics programs. We renew the certification annually and ship the audit summary with the first PO.
Engineering review is the first step in every quote. A cable engineer who has built drag-chain harnesses before looks at your drawing — bend radius, axis of flex, cycle-life target, jacket chemistry, connector environment — and sends DFM notes back before quoting. That is why our first-pass FAI acceptance rate sits above 96% across the programs we have run for the last three years.
In-house capabilities
Engineering-to-shipping under one roof
DFM, prototyping, PPAP, 100% electrical test and continuous-flex validation — no subcontracted assembly, no black-box outsourcing. Your build stays inside the same Class 3 lines from sample to series.
Drag-chain testing 5M+ cycles
In-house dynamic flex rigs validate every build to IEC 60332 / EN 50396 conditions. Reports shipped with the FAI sample.
Continuous-flex copper alloy
Bunched fine-strand tinned copper with PUR or TPE jacket — rated for 10M+ bend cycles at 7.5× cable diameter. Optimised for six-axis robot arms.
Servo motor cables
Pre-assembled servo power + brake + signal cables for major drive families. Pre-fab connectors on the motor side, flying leads on the cabinet side.
Encoder cables
Foil + braid shielded twisted pairs for incremental, SSI, EnDat and BiSS encoders. Drain conductor terminated to shell — no ground loops on the controller side.
Shielded twisted pair
EtherCAT, PROFINET, CC-Link IE and SERCOS III data cables with M12 X-coded or D-coded terminations. 100 Ω impedance verified on every spool.
IP67/68 rated connectors
Sealed M8, M12, M16 and M23 circular connectors. Overmoulded transitions when the application sees coolant, oil or wash-down chemistry.

Why OEMs choose us
17 years building robotics cable assembly for engineers who don't accept “close enough”
- Engineers respond, not sales reps. Every RFQ is routed to a cable engineer who has built six-axis arm harnesses before. You get DFM notes back — not a templated brochure.
- No MOQ — prototype to 50K sets on the same line. Run one verification sample on Monday, scale to 5,000 PPAP-released units by month end. Same operators, same QMS, same IPC/WHMA-A-620 Class 3 acceptance.
- Real flex testing — not data-sheet borrowing. We bench-test each harness under the actual bend radius and axis the design specifies. Reports go in your FAI binder with photographs and date stamps.
- Documentation procurement signs off on. PPAP Level 1–3, FAI per AS9102, material declarations, UL component traceability, ISIR — packaged the way buyers in regulated industries expect to receive it.

FAQ
Common questions before placing your first order
What flex-cycle life can I expect from a continuous-flex robotics cable assembly?
Properly engineered continuous-flex constructions reach 5–10 million bend cycles in 7.5× cable-diameter drag chains and 3–5 million on torsional axes. The actual number depends on bend radius, acceleration, jacket material, conductor stranding and how the strain relief is anchored. We bench-validate the exact configuration before shipping the first production lot and ship the test report with the FAI.
Can you build EtherCAT, PROFINET and SERCOS III cable assemblies?
Yes. All three protocols ship from the same line using 100 Ω impedance-controlled twisted pairs with foil + braid shielding. We hold M12 X-coded, D-coded and A-coded tooling for IP67 termination, and TDR-verify impedance on every assembled cable before it leaves the cell.
What is the lead time for a prototype build?
Prototypes ship in 48 hours when connectors and cable are in our standard stock list (M8, M12, M16, M23 circular; HARTING Han series; D-sub; most servo motor connectors). Custom hybrid connectors or overmould tooling add 2–3 weeks. We confirm the exact lead time on the quote, not after the PO.
Do you sign NDAs before reviewing a robot harness drawing?
Yes — NDA is the first step for every new program. Bilateral templates available, or sign on yours. Drawings, BOMs and FEA results sit behind access control and are not shared outside the engineering review group.
How do you handle PPAP and FAI for automotive-fed robotics programs?
Our IATF 16949 line runs PPAP Level 1–5 on request. Standard package includes DFMEA, PFMEA, control plan, capability studies (Cp/Cpk on crimp height and pull force), dimensional layout per AS9102, material certs and appearance approval. We submit electronically through Covisint, IATF portals or buyer-side systems.
Which side of the world do you ship from, and what is the freight option?
Production is in Shenzhen, China. Air freight via DHL/FedEx (3–5 days door to US/EU), sea freight (28–35 days door to door) and US-stocked buffer programs are all available. Buffer-stock contracts are commonly used by AGV and cobot OEMs to keep field MTBF predictable without holding inventory themselves.
