7 General Electronics Applications: Suitable for business equipment, information devices, and non-safety-critical industrial gear

注意事项 PRECAUTIONS

1 Power Supply: Do not exceed the absolute maximum supply voltage (±18V); incorrect polarity will damage the sensor

2 Installation: Ensure the primary conductor fully fills the through-hole area to achieve specified accuracy; avoid placing near other magnetic field sources (may affect measurement precision)

3 Wiring & Connections: Use twisted or shielded cables for output lines to reduce noise interference; select mating connectors with equivalent terminal plating to prevent galvanic corrosion

4 Operation & Maintenance: Perform zero offset adjustment at startup and regularly (especially after long operation or significant temperature/humidity changes); avoid using in environments with high temperature/humidity, corrosive gases, direct sunlight, liquids, static electricity, electromagnetic radiation, or sealed resin

5 Safety Precautions: The sensor lacks built-in protection circuits; for safety-critical applications, add external protection (fuses, protective circuits) to prevent overheating or ignition in case of failure (short/open circuit)

6 Storage Guidelines: Avoid high-temperature/humidity storage; if stored for over 6 months, check soldering integrity before use (for board-mounted products)

7 Application Restrictions: Not intended for use in medical devices, transportation equipment, high-risk industrial control systems, in-vehicle safety systems, or any application where product failure could lead to loss of life or bodily injury.
