HO 100-SW-0100

Current Sensors Overview

The HO 100-SW-0100 is a current sensor from the HO-SW Series by LEM USA Inc. It features an open-loop Hall effect technology with a bidirectional single channel design. The module supports a primary current rating of 100A and operates within a frequency range of DC to 350kHz. It utilizes a single pass-through configuration for installation. The device requires a supply voltage between 4.5V and 5.5V, with a maximum supply current of unspecified but typical low values. Accuracy is rated at ±1%, and linearity is ±0.5%. The operating temperature range extends from -40°C to 105°C.

Current Sensors Feature Summary

• Open-loop Hall effect technology for non-intrusive current measurement
• Bidirectional sensing capability for AC/DC applications
• Single pass-through module design for simplified integration

Current Sensors Applications

• Industrial motor drive control systems
• Power supply monitoring and protection circuits
• Inverter and converter current feedback loops

Current Sensors Procurement Notes

Verify the specific suffix 'SW' indicates panel mount or specific housing variant compared to standard HO 100-S models. Confirm pinout compatibility with target PCB or terminal block designs. Ensure supply voltage stability within the 4.5V to 5.5V range to maintain specified accuracy and linearity performance during operation.

Current Sensors Selection Notes

Select this model when high bandwidth up to 350kHz is required alongside a 100A current capacity. The open-loop architecture offers cost efficiency compared to closed-loop alternatives. Consider the bidirectional nature if negative current flow detection is necessary. Evaluate thermal management requirements given the 105°C upper operating limit.

Current Sensors Part Context

This component belongs to the HO-S series of current transducers, which are designed for general industrial applications. The HO-SW variant specifically denotes a particular mounting or packaging configuration within this family. These sensors provide galvanic isolation between the primary conductor and the secondary output circuitry.

Current Sensors Replacement Considerations

HO 100-S-0100: Standard open-loop variant without SW suffix modifications. HO 100-P-0100: Different package type within the same series. Verify mechanical footprint and pin assignment differences before substitution.
