Model MGD-HQN202 High-voltage Rated N-pote Electromagnetic Sensor


  • Magnet detection
  • Automatic guided vehicles guidance
  • As it can be used to drive voltage 48 V DC (or less) following electric forklift, refrigeration car, freezer car, etc


  • Uses a magnetism focusing construction (patented) that makes it particularly strong against ambient temperatures.
  • It can be used in a wide range of supply voltage 15 V to 65 V DC.
  • The magnetism focusing construction is very useful as the sensor can detect at a long distance targets with a wide surface but a weak magnetic flux, like belt-shaped rubber magnets.
  • Equipped with protection diodes to protect the sensor from reverse connection to the power supply and output surges.
  • The LEDs displaying
  • Because of the high power supply voltage specification, it can also be used in the battery voltage 48 V DC.

International Standards

  • Our products do not have overseas safety regulations such as CE mark, UL standard, EN standard etc.
  • Products is compliant to the RoHS directive.

* Please consult about "change of specification" and "request of specification" of the product.

Usage Precautions

Usage Precaution

  • When the mounting part or its peripheral materials of the sensor include magnetic metals, separate them from the sensor to the same distance between the magnetic sensor and the magnet tape or more, to ensure the intended detection characteristics.
  • If there is magnetic metal with residual magnetism in the surroundings of the electromagnetic sensor installation location, the detection characteristics may greatly vary. Verify the detection characteristics before using the sensor.
  • See Electromagnetic sensor general usage precautions for other precautions.
