FHS AH 600

Current Sensors Overview

The FHS AH 600 is a coreless, open-loop Hall effect current sensor manufactured by LEM USA Inc. It functions as a galvanically isolated transducer that senses the magnetic field generated by measured current and converts it into an output voltage. The device is designed as a surface-mounted component in an 8-pin SOIC package. It supports bidirectional current measurement with a detection range of up to 100A. The sensor operates on a single supply voltage and provides a proportional voltage output signal for integration into electronic control circuits.

Current Sensors Feature Summary

• Galvanic isolation between primary current path and secondary electronics
• Coreless open-loop Hall effect sensing technology
• Surface-mount device (SMD) construction for automated assembly

Current Sensors Applications

• Industrial motor drive current monitoring
• Power supply output current sensing
• Battery management system current measurement

Current Sensors Procurement Notes

Verify the specific suffix and pin configuration against the official LEM datasheet to ensure compatibility with the target PCB footprint. Confirm that the operating temperature range and supply voltage requirements align with the system design specifications before finalizing procurement decisions.

Current Sensors Selection Notes

Select this component when a compact, surface-mount solution is required for high-current applications up to 100A. The open-loop architecture offers a balance between cost and performance suitable for general industrial monitoring where extreme precision is not critical compared to closed-loop alternatives.

Current Sensors Part Context

This part belongs to the FHS series of coreless current sensors from LEM. Unlike through-hole modules, the FHS AH 600 utilizes a small form-factor SOIC package. It is distinct from the FHS 40 evaluation kit, serving instead as a standalone active component for mass production designs requiring integrated current sensing capabilities.
