Product Overview
The Yokogawa YCB141-M025 serves as a high-performance 25-meter coaxial interconnect designed specifically for the V net and ER bus communication backbones. As a vital component of the CENTUM VP and ProSafe-RS Distributed Control Systems (DCS), this cable facilitates high-speed data exchange between human interface stations (HIS), control stations (FCS), and safety instrumented systems. It adheres to strict 10BASE-2 Ethernet standards, providing the low attenuation and high signal-to-noise ratio required for mission-critical industrial networking.

Engineering Advantages
-
Superior EMI/RFI Suppression: The dual-layer shielding architecture (combining foil and high-density braiding) aggressively mitigates electromagnetic interference. This design prevents signal corruption in environments dominated by high-voltage switchgear and variable frequency drives (VFDs).
-
Minimal Signal Attenuation: The foamed polyethylene dielectric maintains consistent 75 Ω impedance across the entire 25-meter run. This optimizes signal propagation and ensures that the V net communication pulses remain sharp and readable, even at high frequencies up to 3 GHz.
-
Mechanical Integrity in Harsh Zones: High-conductivity copper cores provide excellent tensile strength and flexibility. The cable resists the mechanical stresses of installation in congested cable trays and prevents signal drops caused by vibration or thermal expansion.
-
Optimized for Safety Systems: Because the YCB141-M025 supports the ProSafe-RS platform, it meets the stringent reliability requirements for SIL-rated safety loops. It ensures the constant uptime of safety buses where failure is not an option.
FAQs
Q1: Can I use the YCB141-M025 for standard commercial Ethernet networking?
A1: No. While it adheres to 10BASE-2 standards, Yokogawa tunes this 75 Ω cable specifically for V net and ER bus protocols. Standard commercial Ethernet (10BASE-T/100BASE-TX) uses 100 Ω twisted pair or 50 Ω coax; using this cable in non-Yokogawa systems will cause impedance mismatches and packet loss.
Q2: Does the cable come with pre-installed BNC connectors?
A2: The YCB141-M025 typically arrives factory-terminated to ensure the highest possible connection quality. We recommend against field-cutting or re-terminating this cable, as improper crimping can introduce impedance bumps that disrupt high-speed bus communication.
Q3: How should I handle the minimum bend radius during installation?
A3: To maintain the foamed polyethylene dielectric's structure and the 75 Ω impedance, avoid sharp kinks. Follow the standard industrial guidelines for coaxial cables (typically 10 times the outer diameter) to prevent internal reflection and signal degradation.
Q4: How do I verify the authenticity of this cable?
A4: We supply only 100% Brand New and Original Yokogawa YCB141-M025 cables. Each unit features factory markings along the jacket, including the part number and manufacturer's code, and ships in original Yokogawa packaging with full traceability.
