CR5211-20

Current Sensors Overview

The CR5211-20 is a DC Hall effect current transducer manufactured by CR Magnetics Inc. It provides non-contact sensing for direct currents up to 20A with unidirectional polarization. The device operates on a 24V supply and draws a maximum of 40mA. It features a response time of 250ms and functions within an operating temperature range of 0°C to 50°C. The unit supports panel or DIN rail mounting.

Current Sensors Feature Summary

• Closed-loop magnetic modulation technology ensures high accuracy in DC current measurement
• Non-contact Hall effect sensing eliminates electrical isolation barriers between primary and secondary circuits
• Supports multiple output configurations including ratiometric voltage signals

Current Sensors Applications

• Industrial automation systems requiring precise DC current monitoring
• Power supply units needing feedback control for output regulation
• Battery management systems for charge and discharge current tracking

Current Sensors Procurement Notes

Verify the specific output type required, as the series offers ±5 VDC, ±10 VDC, or 4-20 mADC options. Confirm that the application involves only direct current, as these devices are not suitable for AC measurements. Ensure the mounting method aligns with standard 35mm DIN rail or panel installation requirements specified in the official datasheet.

Current Sensors Selection Notes

Select this component when unidirectional DC current monitoring is necessary with galvanic isolation. The 20A rating suits moderate power applications. Consider the 250ms response time against system speed requirements. Verify supply voltage compatibility with the 24V specification and ensure thermal conditions remain within the 0°C to 50°C operational envelope.

Current Sensors Part Context

This model belongs to the CR5211 series of solid-core Hall effect transducers. It shares design principles with related models like the CR5211-10 but differs in current capacity. The series utilizes advanced magnetic modulation for stability. It is distinct from the CR5210 series which employs different sensing technologies.

Current Sensors Replacement Considerations

Direct substitutes include other CR5211 variants with matching current ratings. Cross-reference pinouts and output types carefully. No generic industry replacements are confirmed without verifying exact electrical parameters.
