Yokogawa KS1-20 Signal Cable

Product Introduction

The Yokogawa KS1-20 Signal Cable is a high-performance, shielded signal cable designed for industrial automation and process control environments. As a heavy-duty variant within Yokogawa’s KS series, the KS1-20 provides enhanced signal integrity and mechanical strength for critical applications where signal reliability is non-negotiable.

This cable is specifically engineered for use in Yokogawa Distributed Control Systems (DCS), field instrumentation, and high-noise environments where electromagnetic interference (EMI) is a major concern. The KS1-20 is widely recognized for its robust construction, superior shielding, and long-term operational durability, even in harsh industrial conditions such as petrochemical plants, offshore rigs, and power stations.

Its thick conductor, reinforced insulation, and double shielding make it suitable for both analog and digital signal transmission across extended distances, ensuring minimal signal loss and high resistance to noise.

Product Applications

The KS1-20 Signal Cable is used extensively in demanding industrial sectors where both mechanical endurance and high-quality signal transmission are required. Its primary application domains include:

  • Distributed Control Systems (DCS): Ideal for long-distance analog/digital signal transmission from field instruments to the central control room.

  • Field Instrumentation Wiring: Connects transmitters, sensors, analyzers, and final control elements in hazardous zones.

  • Power Plants: Used for instrumentation in turbines, boilers, and auxiliary equipment monitoring.

  • Petrochemical and Refinery Operations: Designed to handle environmental challenges including EMI, temperature changes, and vibration.

  • Water & Wastewater Treatment: Carries sensor feedback (e.g., pH, pressure, flow) in SCADA-integrated systems.

  • Marine and Offshore Rigs: Corrosion-resistant design makes it suitable for salt-laden air and vibration-prone installations.


Key Advantages

  • Superior Noise Immunity
    Dual shielding with aluminum foil and copper braid drastically reduces susceptibility to electromagnetic interference.

  • Durability in Harsh Conditions
    XLPE insulation and rugged outer sheath provide resistance against oil, chemicals, abrasion, and high temperatures.

  • Reliable Signal Integrity
    The thick copper conductor ensures low attenuation, preserving signal quality over long distances.

  • Versatility
    Suitable for both analog and digital signal types across a wide range of industrial protocols (e.g., HART, 4–20 mA, RS-485).

  • Safety-Compliant
    Flame-retardant and low-smoke materials reduce fire hazard and ensure regulatory compliance.

  • Mechanical Strength
    Withstands cable tension, compression, and vibration—ideal for fixed and dynamic installations.

  • Seamless Integration
    Designed to work with Yokogawa’s full suite of I/O modules, controllers, and terminal panels.


Frequently Asked Questions (FAQ)

1. What is the main difference between KS1-10 and KS1-20 cables?
The KS1-20 uses a thicker conductor (1.25 mm² vs. 0.75 mm²) and dual shielding, offering better noise protection and signal performance over long distances.

2. Can the KS1-20 be used for both analog and digital signals?
Yes, it is suitable for both analog (e.g., 4–20 mA) and digital protocols (e.g., RS-485, Modbus).

3. Is this cable flame-retardant?
Yes, the standard sheath is flame-retardant PVC, and LSZH versions are available for fire-critical zones.

4. Can I use this cable outdoors?
While designed for industrial interiors, KS1-20 can be used outdoors if installed in protective conduits or trays.

5. Does this cable support HART communication?
Yes, its low capacitance and shielding quality make it ideal for HART-enabled instrumentation.

6. What is the expected lifespan of the KS1-20?
Under normal industrial conditions, the cable can last 10–15 years or more without significant degradation.

7. Is it compatible with third-party control systems?
Yes, it can be used with other systems as long as voltage and insulation parameters match.

8. Can I terminate the cable myself?
Yes, standard tools and connectors compatible with 1.25 mm² cores are sufficient for field termination.

9. Is the shielding grounded?
The cable includes a drain wire for proper grounding of the shield to reduce interference.

10. Is customization possible for color coding or length?
Yes, Yokogawa and its distributors offer custom color coding and roll lengths based on project requirements.
