AIMH040-800A-420

Current Sensors Overview

The AIMH040-800A-420 is a Hall effect current sensor manufactured by Aim Dynamics. It features a single channel design with unidirectional measurement capability for DC currents up to 800A. The device utilizes a split-core module configuration with a 40mm single pass-through opening, facilitating non-intrusive installation on busbars or cables. It provides a 4-20mA analog output signal proportional to the measured current. The unit operates within a temperature range of -10°C to 85°C and has a maximum supply current of 35mA.

Current Sensors Feature Summary

• Hall effect sensing technology for accurate current measurement
• Split-core module design allowing easy installation without circuit interruption

• Standardized 4-20mA output signal for industrial integration

Current Sensors Applications

• DC power distribution systems monitoring
• Battery management system current tracking
• Industrial motor drive current feedback
• Renewable energy inverter input current measurement

Current Sensors Procurement Notes

Verify that the specific part number matches the required 4-20mA output variant, as the AIMH040 series includes other output types such as 5V or ±5V. Confirm the unidirectional specification aligns with your application's current flow direction. Ensure the 40mm aperture size accommodates the target conductor diameter. Check operating temperature requirements against the -10°C to 85°C rating. Always request the official datasheet from Aim Dynamics or authorized distributors to confirm electrical characteristics and pinout definitions before procurement.

Current Sensors Selection Notes

Select this model when a non-invasive solution for high-current DC measurement is required. The 800A rating suits heavy-duty applications where standard shunt resistors may introduce excessive loss. The 4-20mA output is preferred for long-distance transmission in noisy industrial environments due to its immunity to voltage drops. Consider the split-core form factor if retrofitting existing installations is necessary. Compare with bidirectional variants if reverse current flow needs to be detected.

Current Sensors Part Context

This component belongs to the AIMH040 series of split-core Hall effect current transducers from Aim Dynamics. The series offers various current ratings including 500A, 800A, and 1000A, with different output options like 5V, ±5V, and 4-20mA. The AIMH040-800A-420 specifically denotes the 800A capacity with 4-20mA output. Similar models include the AIMH040-500A-420B and AIMH040-800A-5V, differing in current rating or output type.

Current Sensors Replacement Considerations

Direct substitutes within the same family include the AIMH040-500A-420B if lower current capacity is acceptable, provided the output remains 4-20mA. Cross-manufacturer replacements require matching the 40mm aperture, 800A rating, and 4-20mA output. Verify mechanical dimensions and mounting style compatibility. Ensure the replacement maintains the same accuracy class and operating temperature range.
