PLCs, Power Supplies & Others

This Yokogawa insulating bush provides electrical isolation for mounting components on I/O modules. It prevents unwanted current paths between circuit boards and chassis ground planes. Engineers can rely on this component for maintaining system integrity in critical applications. Its precision molding ensures consistent dimensions for reliable panel installations. The bush simplifies assembly through straightforward press-fit insertion into standard mounting holes.

Physical Dimensions and Material Composition

The insulating bush measures 6.0 mm in outer diameter and 3.0 mm in height. Its inner diameter accommodates M2.5 screws for secure component fastening. The unit weighs approximately 0.5 grams for minimal impact on overall assembly. A high-grade polyamide material provides excellent dielectric strength for electrical insulation. This material resists chemical degradation from common industrial solvents and cleaning agents.

Electrical Characteristics and Dielectric Performance

The bush offers a dielectric strength of 500 VAC for reliable voltage isolation. Its insulation resistance exceeds 1000 MΩ under standard test conditions. The component withstands continuous operating voltages up to 250 VAC. This rating ensures safe operation within standard Centum VP I/O modules. The bush maintains its insulating properties across varying temperature and humidity levels.

Thermal Stability and Operating Ranges

The bush operates reliably from -20 to 85 degrees Celsius ambient temperature. Its material retains dimensional stability throughout this wide thermal range. The component withstands short-term exposure to 105 degrees Celsius during soldering operations. This thermal tolerance simplifies automated assembly processes considerably. The bush does not soften or deform under normal operating heat conditions.

Mechanical Durability and Installation Specifications

The bush accepts standard M2.5 screws with a maximum torque of 0.3 N·m. This torque specification prevents material damage during installation. The component accommodates panel thicknesses from 0.8 to 1.6 millimeters effectively. Its flanged design provides positive seating and prevents over-insertion. The bush supports repeated screw insertion and removal cycles without degradation.

Packaging and Delivery Configuration

The manufacturer supplies these bushes in quantities of 100 pieces per package. Each package includes a sealed anti-static bag for contamination protection. The plastic bag also prevents moisture absorption during storage and transit. This packaging ensures component cleanliness upon arrival at installation sites. The bush requires no special storage conditions beyond normal warehouse environments.

Application and System Compatibility

The insulating bush finds primary use in Centum VP and ProSafe-RS I/O modules. It functions as a mounting isolator for termination boards and interface units. The component also suits general industrial electronic equipment requiring PCB isolation. Its compatibility extends to various third-party industrial control systems. This versatility reduces inventory requirements for maintenance stockrooms.
