  • Q The malfunction of magnetic sensor
    A

    Check wiring

    ■  Correct：Remove magnetic sensor from cylinder, and use a magnet to test the sensor.
    1. Sensor works：the magnetic field of the magnet inside the cylinder is not enough or the sensitivity of magnetic sensor is too weak. Please contact our RD  department.
    2. Sensor doesn't work：Please send back for examination.

    ■  Wrong：Please correct it.

      
  • Q Contact point is unbreakable
    A

    Check whether the magnetic sensor is overloaded.

    ■  No：Check the wire distance between the magnetic sensor and the load is more than 10M or not.
    1. Over 10M：Add an inductor (About 1000uH) to eliminate to capacitor impulse caused by long wiring.
    2. Below 10M：Please send back for examination.

    ■  Yes：
    1. Exchange magnetic sensor with larger rated operating voltage, current, and contact rating.
    2. Use relay or PLC to drive the load indirectly.
  • Q The LED flashes and turns off
    A

    Check whether the loading current is too high.

    ■  Yes：
    1. Exchange magnetic sensor with larger rated operating voltage, current, and contact rating. 《Please refer to the figure below》
    2. Use relay or PLC to drive the load indirectly.
    ■  No：Please send back for examination.
  • Q Magnetic sensor operates twice continuously
    A
    The magnetic field of magnet is too strong or the sensitivity of magnetic sensor is too high.
    Please contact to our RD department.
