Hardware Specifications

Industrial Network Connectivity and Signal Integrity

The YCB141-M025 is engineered to maintain low-latency data flow within Yokogawa CENTUM VP and ProSafe-RS architectures. The cable utilizes intrinsic safety (Ex i) barrier-compatible construction where required and provides DIN-rail mounting stability when used in conjunction with secondary conduit routing. The coaxial structure offers surge voltage protection limits necessary for maintaining communication link stability in high-EMI industrial zones. By adhering to 10BASE-2 standards, the cable ensures protocol conversion latencies are kept within the precise millisecond tolerances required for deterministic V net communication.

Frequently Asked Questions

Q: Can the cable be spliced if a shorter distance is required?

A: No. Splicing or modifying the coaxial length alters the characteristic impedance of the cable, which will cause signal reflections, packet loss, and potential failure of the V net or ER bus communication link.

Q: Are there specific bending radius requirements for this coaxial cable?

A: Yes. To prevent physical damage to the internal conductor or shielding, maintain a bending radius of at least 10 times the outer diameter of the cable during installation in control cabinets or rack systems.

Field Installation Guidelines

1. Inspect the BNC connectors for any debris or oxidation before mating; ensure a firm, locking connection is achieved to prevent intermittent signal drops.
2. Route the cable through dedicated electrical conduits or cable trays, maintaining physical separation from high-voltage power lines to prevent induced electromagnetic noise.
3. Ensure the cable shields are grounded at the designated common potential points within the cabinet to maintain the EMI-resistant properties of the coaxial design.
4. Avoid excessive tension during the pulling process; use appropriate cable lubricants if routing through constrained conduit paths to prevent structural deformation of the dielectric.
5. Once installed, verify the continuity of the shield and the center conductor to ensure no shorts or open circuits exist prior to energizing the network segment.
