Matters needing attention:

  • The wrong connection may cause sensor damage. After the sensor is energized, the same phase voltage is measured at the output when the current wire cross the sensor center according the direction arrow indicating label.

  • The output range of the sensor can be adjusted according to the user's needs.

  • During the installation process, before closing the jaw, make sure the connecting interface is aligned, not forcibly closed
