Current Sensors Procurement Notes

Verify the specific model suffix against official manufacturer documentation to confirm exact electrical characteristics and mounting requirements. Ensure that the procurement channel provides valid traceability for industrial components. Cross-reference the part number with the latest datasheet to confirm availability status and any potential obsolescence notices before finalizing orders.

Current Sensors Selection Notes

Select this component when measuring AC currents up to 500mA with high precision is required. The 4-20mA output facilitates easy integration into existing PLC or SCADA architectures. Consider the bidirectional nature if reverse current flow must be monitored. Verify that the operating temperature range and environmental conditions match the installation site specifications.

Current Sensors Part Context

This part belongs to the CR4220S series of current transducers from CR Magnetics Inc., which covers a wide range of AC current measurements from 10A to 6000A. The series is known for its modular design and reliability in industrial environments. The CR4220S-0.5 specifically addresses the lower end of the current spectrum, offering a specialized solution for sensitive low-amperage applications where standard higher-range sensors would lack necessary resolution.

Current Sensors Replacement Considerations

Direct substitutes may include other models within the CR4220S series with similar current ratings, such as CR4220S-1 or CR4220S-5, depending on the specific application current. Always verify pinout compatibility and output signal type before substitution.
