AIMH021-200A-420

Current Sensors Overview

The AIMH021-200A-420 is a Hall Effect current sensor manufactured by Aim Dynamics. It features a single-channel, unidirectional design with a split-core module configuration for single pass-through installation. The device provides a 4-20mA analog output signal corresponding to measured current. It has a maximum primary current rating of 200A and includes a 21mm opening diameter for conductor passage. The unit requires an external 12Vdc power supply with a maximum consumption of 35mA.

Current Sensors Feature Summary

• Utilizes Hall Effect technology for non-contact current measurement
• Features a split-core module design allowing installation without disconnecting conductors
• Provides a standard 4-20mA analog output signal
• Factory calibrated to eliminate offset noise voltage

Current Sensors Applications

• Low frequency AC current measurement
• Industrial equipment monitoring
• Power electronics applications
• Electrical instrumentation systems

Current Sensors Procurement Notes

Verify the specific model suffix against official Aim Dynamics documentation to confirm the output type. The 420 suffix indicates a 4-20mA unidirectional output, whereas other variants may offer different signals or bidirectional capabilities. Ensure the required 12Vdc power supply is included in the system design as it is not part of the sensor module itself. Confirm the 21mm aperture size matches the target conductor dimensions before procurement.

Current Sensors Selection Notes

Select this component when a unidirectional current measurement up to 200A is required with a 4-20mA interface. The split-core architecture is suitable for retrofits where breaking the circuit is not feasible. Consider the 1% accuracy specification for precision requirements. Verify that the application operates within the low-frequency range where traditional current transformers are ineffective. Ensure the system can provide the necessary 12Vdc supply at 35mA maximum consumption.

Current Sensors Part Context

The AIMH021 series comprises Hall Effect current transducers designed for accurate current sensing. This specific model belongs to the 420 output variant family, distinguished by its 4-20mA signal generation. The series is characterized by factory calibration and split-core construction, offering flexibility in installation compared to solid-core alternatives. Aim Dynamics positions these sensors for industrial and electronic applications requiring reliable non-invasive monitoring.

Current Sensors Replacement Considerations

Cross-reference with other AIMH021 variants such as the 420T or 5V series if different output signals or bidirectional functionality are needed. Verify that substitute models maintain the 21mm aperture and 200A rating. Ensure any replacement supports the same 12Vdc power requirement and 4-20mA interface compatibility.
