Hardware Specifications

Industrial Network Connectivity and Signal Integrity

The YCB111-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 assembly offers surge voltage protection limits necessary for maintaining communication link stability in high-EMI industrial zones. By adhering to 10BASE-5 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 YCB111-M025 be used in areas with high vibration?

A: Yes. The industrial-grade flame-retardant jacket and robust shielding allow for installation in high-vibration areas, provided the cable is securely fastened at regular intervals to prevent mechanical fatigue at the termination points.

Q: What is the minimum bending radius for this cable during installation?

A: The minimum bending radius for permanent installation is 100 mm. Exceeding this limit by creating tighter bends will cause deformation of the coaxial core, leading to impedance mismatch and signal reflection.

Field Installation Guidelines

1. Inspect the M4 screw terminals and solderless lugs for cleanliness before termination; ensure a torque consistent with industrial terminal block standards to provide a gas-tight connection.
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/RFI rejection properties of the high-density braid.
4. Use appropriate cable pulling equipment to avoid exceeding the maximum tensile strength of the cable during installation in long conduit runs.
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.
