Model MGD-QW501/QW202 Bipolar detection high-sensitivity electromagnetic sensor

Application

  • Magnet detection
  • Automatic guided vehicles guidance

Features

  • Uses a magnetism focusing construction (patented) that makes it particularly strong against ambient temperatures.
  • 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.

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

  • 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.
