Model MGD-HQW501 High-voltage rated bipolar detection electromagnetic sensor

Application

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

Features

  • 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 DC 15 V to 65 V.
  • 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.
  • The detected poles (N pole and S pole) are output separately.
  • Equipped with protection diodes to protect the sensor from reverse connection to the power supply and output surges.
  • The LEDs displaying the operation (red for N pole detection and green for S pole detection) make it easy to grasp the operation condition.
  • Because of the high power supply voltage specification, it can also be used in the battery voltage DC 48 V.

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.

Usage precautions

Usage precaution

  • If the object on which the electromagnetic sensor is installed is made of magnetic metal, the detection sensitivity may greatly vary. In such a case, place it at 40 mm above the installation surface and verify the detection characteristics before using the sensor.
  • 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.
