Robot Arm Cable – Highly Flexible, 3-Pair 28AWG, PUR Shielded

Engineered for automated industrial machinery, this high-flex robot cable is built to withstand continuous reciprocating motion, frequent bending, and torsional stress in robotic arms, pick-and-place systems, and moving machine parts. It delivers reliable signal integrity in both dry and damp environments, indoors or outdoors, without the risk of core breakage under repetitive flex cycles.

Key Performance Features

The USA-imported PUR jacket gives this robot cable outstanding mechanical toughness and environmental resistance, enabling it to handle the most demanding automated motion:

• Exceptional flexibility and torsion resistance – withstands high-speed, multi-axis robotic arm movements without jacket deformation or conductor fatigue

• High abrasion and cut resistance – survives contact with machine frames and cable carriers

• Oil and chemical resistance – performs reliably in environments exposed to mineral oils, coolants, acids, and alkalis

• UV and weather resistance – fully qualified for outdoor installations with prolonged sun exposure

• Cold temperature flexibility – remains pliable down to -40°C, making it suitable for cold storage and unheated factory areas

• Long flex life – optimized lay length, fine copper stranding, and tough PUR jacket dramatically reduce downtime caused by cable failure

Recommended Applications

• Internal wiring of articulated robot arms and multi‑axis robots

• Automated production lines, packaging machinery, and pick-and-place modules

• Cable tracks and energy chains exposed to constant bending and acceleration

• Industrial signal transmission under continuous motion – sensors, encoders, and control circuits

• Dry and damp indoor areas, as well as outdoor installations requiring UV‑stable cabling

Frequently Asked Questions

What is the minimum bend radius for this robot cable, and how does it affect service life?
For fixed wiring, the bend radius should not be less than 5 times the outer cable diameter. In flexing applications – such as inside a cable carrier or on a robotic arm – maintaining a radius of 8–10 times the outer diameter is critical to achieving maximum flex life. Tighter bends accelerate fatigue and may shorten the cable’s service life.

Can you provide this cable with different AWG sizes, pair counts, or jacket colors?
Yes. Our engineering team regularly customizes robot cables. You can specify alternative conductor sizes, additional twisted pairs, and special jacket colors. Black is standard, but we can match your equipment color scheme. Minimum order quantities may apply, and we are happy to advise on the optimal configuration for your motion requirements.

Is this cable suitable for high-speed cable carrier (drag chain) applications?
Absolutely. The extra-fine Class 6 copper strands, specially formulated PUR jacket, and optimized lay length are specifically designed for continuous flexing in cable tracks. To ensure the best match, please share the travel distance, acceleration, and target bending radius of your application – our application engineers will verify suitability and recommend the ideal cable construction.

What certifications and test reports can you supply?
This product is manufactured and tested in accordance with UL758 and JB/T 8734. We provide standard factory test reports and certificates of conformance. Should your project require full UL listing, CE marking, or other regional certifications, please contact us with the specific requirements – our team will guide you through the available compliance documentation.
