Current Sensors Procurement Notes

Verify the specific model suffix against official datasheets to confirm the rated current and channel configuration, as variations exist within the CR4260 series. Ensure the application environment falls within the specified operating temperature range and frequency limits. Confirm that the loop power supply meets the required voltage specifications for proper signal generation. Cross-reference part numbers with manufacturer catalogs to avoid confusion with similar models in the CR4210 or CR4400 series.

Current Sensors Selection Notes

Select this component when precise monitoring of low-range AC currents up to 0.5 A is required. The loop-powered design eliminates the need for separate signal power supplies, simplifying wiring in industrial control environments. Consider the bidirectional capability if reverse current flow must be detected. Verify compatibility with existing PLC or instrumentation inputs accepting standard 4-20 mA signals. Evaluate the solid core construction for ease of installation without breaking primary conductors.

Current Sensors Part Context

The CR4260-0.5 belongs to the CR4260 series of solid core current transmitters manufactured by CR Magnetics Inc. This series is engineered for long-range monitoring of AC sinusoidal currents using a robust transformer-based design. The modules are characterized by their loop-powered functionality, which derives energy from the output signal loop itself. The series includes various models differentiated by rated current and channel count, all sharing common features such as high accuracy and DIN rail mountability.

Current Sensors Replacement Considerations

Direct substitutes may include other models within the CR4260 series with matching current ratings, such as CR4260-5 for higher current applications. Compare technical specifications carefully, particularly the rated current, accuracy, and output signal type. Ensure that any replacement maintains the same loop-powered architecture and mounting style. Consult official manufacturer documentation for cross-reference information before implementing changes.
