AIMH021-050A-420B

Current Sensors Overview

The AIMH021-050A-420B is a split-core Hall effect current transducer manufactured by Aim Dynamics. It features a single-pass-through design with a 21mm opening, suitable for non-intrusive installation on busbars or cables. The device provides a 4-20mA analog output signal corresponding to the sensed current. It supports a maximum sensing current of 50A and maintains an accuracy class of ±1%. The module operates within a temperature range of -10°C to 85°C and requires a supply voltage of ±15V, drawing a maximum supply current of 35mA. This configuration allows for bidirectional current measurement in DC applications.

Current Sensors Procurement Notes

Verify that the specific part number includes the '420B' suffix to confirm the 4-20mA output variant. Ensure the application environment remains within the specified -10°C to 85°C operating temperature range. Confirm that the available ±15V supply voltage matches the sensor requirements. Check that the conductor diameter fits within the 21mm split-core opening. Validate that the ±1% accuracy meets the system's precision needs before finalizing procurement.

Current Sensors Selection Notes

Select this model when a non-invasive solution for DC current monitoring is required. Choose this variant specifically for its 4-20mA output compatibility with standard industrial controllers. Consider the 50A rating to ensure it covers the maximum expected load current. Evaluate the split-core design benefits for retrofitting existing installations where breaking the circuit is not feasible. Compare against ±5V output models if different interface standards are preferred.

Current Sensors Part Context

This component belongs to the AIMH021 series of Hall effect current transducers from Aim Dynamics. The series offers various output options including ±5V, 5Vdc, and 4-20mA signals. The AIMH021-050A-420B specifically denotes the 50A sensing capacity with the 4-20mA output configuration. Other variants in the family include unidirectional versions and different current ratings such as 25A, 100A, and 200A, all sharing the same split-core mechanical form factor.

Current Sensors Replacement Considerations

Direct replacements must match the 4-20mA output type and 50A rating. The AIMH021-050A-420T is a related variant but may differ in specific terminal configurations or packaging. Verify pinout compatibility and mounting dimensions before substitution. Ensure the replacement unit also supports bidirectional sensing if required by the application.
