Cable Structure

Yoshinogawa Electric Wire & Cable is long-lasting.

Robot cables require durability for various types of movements,
but no any single cable is universally suitable for all motions.
We design cables tailored to our customers' specific movement needs.

Examples

For Bending Motion

Uses an elastic sheath material to reduce repeated stress on the cable.
Designed to alleviate localized stress concentration.

EXAMPLE：
Tensile load: W = 500g
Bending radius: R = 20mm
Durability test: Withstood 5 million twisting cycles

For U-Bending Motion

A soft sheath material is used to reduce friction between cables and with its guide holder
The bending radius (R) is also important being considered

EXAMPLE：
Stroke (S) = 500㎜
Radius (R) = 50㎜
Durability test: Withstood 20 million U-bending cycles

For Twisting Motion

Among movable conditions, where cables are subjected to significant stress, the cable is designed with a twisted structure that minimizes the torsional stress applied to the conductor.

EXAMPLE：
Twisting θ = ±280°
Stroke (L) = 700㎜
Durability test: Withstood 20 million Twisting Motion cycles

Example of Composite Cables

Features

We can integrate different types of wires , including signal wires, power lines, coaxial cables, tubes, compensating copper wires, and tension members into a single cable.

Application

• Perfect for narrow spaces.
• Cases where the cable must support its own tension, such as in logistics cranes.
• Wiring requiring cable self-support.

Example of Curling (coiling) cables

• Rotational absorption
• Axis or Swivel
• High-Flex and High-Speed

We offering curling (coiling) processing on cables of various sizes and core counts, including composite cables.
For cable sheath , we using polyurethane as material to we ensure long-term shape retention in addition to standard one.

Example of Self-Supporting Cables

Features

Self-supporting cables integrate necessary power lines, signal lines, and air tubes into a single composite cable with controlled rigidity.
This design enables flex-free wiring in twisting and bending movements.

• Reduces weight and size
• Simplifies wiring work

Application

Ideal for applications requiring self-supporting wiring, such as SCARA robots and Cartesian robots

Example of Flat Cables

• Reduces stress
• Improved durability
• Longer lifespan

Using flat cables in cable carriers eliminates the friction between individual round cables, reducing sheath abrasion and dust generation.

Adhesive-Bonded

• Allowing modification of specific sections as needed such as branching or 90-degree bends during installation.
• Ideal for applications such as wiring consolidation for XY stages.

Fully Molded Types

• Compatible with long-length applications.
• More cost-effective than adhesive types.

Yoshinogawa Electric Wire & Cable's durability

Yoshinogawa Electric Wire & Cable's durability is based on a wealth of experience, enabling us to design cables that are optimally suited to our customers' usage conditions.
Furthermore, we conduct durability and evaluation tests on actual cables in accordance with customer requests.
