Yokogawa KS1-20 Style B Signal Cable (40-40 Pins)

Product Overview

The Yokogawa KS1-20 acts as a high-integrity signal transmission bridge between I/O modules and terminal boards within the CENTUM series architecture. This 40-to-40 pin interface cable handles multi-channel analog and digital data routing with minimal signal attenuation. Engineered for long-distance cabinet-to-cabinet patching, this cable ensures seamless communication across the process control network. We supply this product as 100% Brand New, ensuring factory-certified conductivity and insulation for mission-critical applications.

Part Number Breakdown

The KS1 series follows a modular nomenclature to define connector type, length, and hardware revision:

Technical Specifications

The KS1-20 provides a robust physical link designed to withstand the rigors of industrial cabinet environments.

• Manufacturer: Yokogawa

• Interface Type: 40-pin to 40-pin connectors

• Cable Length: 20 Meters (Maximum standard length)

• Style Code: Style B (Current revision)

• Application: Connects I/O modules to terminal units or power distribution boards

• Signal Type: Multi-core signal transmission

Engineering Advantages

The KS1-20 addresses critical wiring challenges in large-scale plant deployments:

• Extended Reach for Remote Racks: The 20-meter length permits flexible positioning of terminal boards relative to the CPU or I/O rack. This solves the problem of rigid cabinet layouts and allows engineers to centralize field wiring in separate enclosures.

• High-Density Connector Design: The 40-pin interface consolidates multiple signal loops into a single assembly. This reduces cable clutter, simplifies cable management, and significantly cuts down on labor hours during system commissioning.

• Signal Cross-talk Suppression: The Style B revision incorporates improved internal twisting and shielding techniques. These features reject electromagnetic interference (EMI) from nearby power cables, maintaining the accuracy of sensitive 4-20mA analog loops.

• Secure Connection Locking: The industrial-grade connectors include mechanical fastening mechanisms. This prevents accidental disconnection caused by vibration or cable strain, ensuring 24/7 process uptime.

FAQs

Can I cut the KS1-20 to a shorter length in the field?

We strongly advise against field modifications. Yokogawa factory-terminates these cables with precision-molded connectors and rigorous continuity testing. Altering the cable length manually voids the warranty and risks signal integrity issues due to improper shielding termination.

How does Style B differ from the original Style A?

Style B represents a hardware improvement in materials and shielding effectiveness. While typically backward compatible with Style A applications, Style B offers superior mechanical durability and better resistance to environmental degradation in harsh industrial atmospheres.

What is the minimum bend radius for the KS1-20?

During installation, technicians must maintain a bend radius of at least six times the cable diameter. Sharp bends can damage the internal 40-core structure, leading to intermittent signal failure or permanent conductor breakage.
