HXS20-NP - LEM

HXS20-NP Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the HXS20-NP?
  LEM Holdings SSA recommends a symmetrical PCB layout with a solid ground plane, and keeping the high-frequency signals away from the low-frequency signals. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is also recommended.
• How do I ensure accurate current measurement with the HXS20-NP?
  To ensure accurate current measurement, it's essential to follow the recommended PCB layout, use a low-impedance current path, and minimize the distance between the current conductor and the sensor. Additionally, calibrate the sensor according to the datasheet instructions.
• What is the maximum operating temperature range for the HXS20-NP?
  The HXS20-NP can operate within a temperature range of -40°C to 125°C. However, the accuracy and linearity of the sensor may degrade at extreme temperatures. It's recommended to operate the sensor within the specified temperature range for optimal performance.
• Can I use the HXS20-NP in a high-vibration environment?
  Yes, the HXS20-NP is designed to withstand high-vibration environments. However, it's essential to ensure that the sensor is properly mounted and secured to the PCB to prevent mechanical stress and damage.
• How do I handle electromagnetic interference (EMI) when using the HXS20-NP?
  To minimize EMI, use a shielded cable for the current conductor, keep the sensor away from high-frequency sources, and use a ferrite bead or common-mode choke to filter out high-frequency noise.
