What are Robot cables?
What are Robot cables?
Simply put, Robot cables are cables used inside an industrial robot or for its equipment.
(they are also called movable cables or FA cables.)
At first glance, they look no different from typical standard cables, but there are one big difference.
The point is that Robot cables have the ability to bend and twist.
In the case of 6 axis robot and SCARA robot, each axis moves like a human arm, so the cables wired to the robot are subjected to bending and twisting movements.
Ordinary standard cables cannot withstand this bending and twisting and will break.
However, Robot cables are designed with flexibility and twisting ability so that they can withstand these harsh movements.
This is a major difference from standard cables.
Robot cables structure
So what kind of structure does it have?
The general structure is as follows:
So then, we will introduce the roles of each department.
Conductor
Conductor is responsible for transmitting electricity such as power and signals.
When it comes to the conductor material, DYDEN uses copper for three reasons: low resistance, cost, and light weight.
In addition, the conductor wires are made of ultra-fine wires the size of a hair, and several of these ultra-fine wires are twisted together and then the bundles are twisted together.
This configuration improves flexibility compared to the conductors used in standard cables. *In the case of standard cables, the conductor wires are twisted together as they are.
Insulation
Insulation serves the purpose of blocking the conduction of electricity. We use insulating materials that are "hard and slippery" to prevent wire breakage.
If the insulation is soft, it may bend locally, leading to premature breakage.
Furthermore, if the insulation does not slide smoothly, the assembly of the insulated wire core may become disrupted, which may lead to breakage.
In addition, we use "special elastomers" and "ETFE" as insulating materials that are hard and slippery.
- Robot cable series with special elastomer insulation・・・RMDH, RMDV
- Robot cable series with ETFE insulation・・・RMFEV
Shield
Shield serves the purpose of preventing noise.
We have adopted braided shield after taking into consideration factors such as bending resistance and shielding effect.
Furthermore, Robot cables with braided shield have "-SB" in the model number.
e.g. RMDH-SB、RMFEV-SB
Jacket
Jacket serves the purpose of preventing external damage and providing oil resistance.
For this reason,taking into consideration the flame retardancy and oil resistance of the sheath, we use flame-retardant・oil-resistant PVC.
Moreover,we also offer special conductor, special shield, and special jacket depending on the usage environment. Details are available here.
About DYDEN's Robot cables
Three features
There are several manufacturers of Robot cables, including us, but among them, "What are the features of DYDEN's Robot cables...?" Our Robot cables have three main features.
More than 40 years of experience and data (reliability)
We have been dealing in Robot cables for over 40 years, since we began manufacturing them in 1983.
We have over 80 testing machines capable of ±90° bending, torsion, and cable gude motion, and the know-how and technical capabilities we have accumulated by repeatedly conducting rigorous tests have ensured the long life and durability of our Robot cables.
▼For more information about the test machine, you can check here.
Custom design suggestions!
We also carry out custom designs according to customer requests based on the product lineup listed on our website.
The RMDH Series, RMDV Series, RMFEV Series, and RMCV Series are available as custom series.
For example, we can accommodate a variety of requests, such as combining power lines and signal lines, as shown in the image, or consolidating multiple cables into one.
In particular, consolidating multiple cables into one is ideal for use in tight wiring spaces such as inside robots, and has been well received by many customers.
▼For more information on custom designs, please see this page.
In-house material development!
We develop cable materials in-house that are optimal for each customer's intended use.
For example, the "RMDH Series" uses a special elastomer, an insulating material developed in-house.
The RMDH series is a cable created in response to customer requests such as "I want to make my robots smaller" and "I want to save wiring space." In order to reduce the outer diameter of the cable, the insulation thickness can be thinned, and a thinner cable diameter means a smaller robot and more space-saving wiring.
In this way, we also develop materials in-house to meet the needs of our customers.

Market share in Japan
With these three features, our Robot cables have been highly praised by major robot manufacturers and others.
Despite being in a highly competitive industry, we have maintained the number one market share in Japan for many years.
Summary
This article introduced the overview of Robot cables (how they differ from general standard cables), their structure, three features, and their market share in Japan. Finally, we have summarized the contents of this article below:
▼Summary of this article
