104MG3

MG Series, rare earth pressed bar magnet, 3,96 mm W x 1,98 mm H x 1.02 mm Dia. [0.156 in W x 0.078 in H x 0.04 in Dia.], 125 pieces per tube

The MG Series Magnets are available in various compact configurations, strengths, and magnetic materials and are intended for use as actuators for Hall-effect and magnetoresistive sensor ICs with unipolar or omnipolar magnetic characteristics. These magnets are designed to provide minimum magnetic fields at a specified distance to help system designers match the appropriate magnet to their requirements.

Produkt Merkmale

Kenndaten

  • Variety of sizes, shapes, and packaging options
  • Different magnetic materials allow customers to choose the most suitable option for their applications:
    • Alnico versions exhibit good physical strength
    • Rare earth (SmCo – Samarium Cobalt) versions offer strong magnetic fields
  • Good stability over a wide operating temperature range (-40 °C to 300 °C [-40 °F to 572 °F]) inclusive
  • Wide selection of operating magnetic Gauss levels
  • Metal or plastic threaded bushings available for easy installation

Anwendungsbereiche

Industrial:

  • Door or lid closure detection in appliances and electronically controlled containers: A magnet embedded in the door or lid actuates a unipolar Hall-effect sensor IC recessed in the door frame, providing open and close position information
  • Simple speed and RPM (revolutions per minute) sensing in fitness and industrial equipment: A magnet of appropriate polarity mounted on a treadmill motor shaft actuates a unipolar Hall-effect sensor IC which generates a single digital pulse for each revolution, providing equipment speed or RPM

Medical:

  • Position sensor in hospital beds and medical equipment: Magnets mounted on equipment activator arms provide home or end-of-travel position
  • Medication bin monitor on portable drug carts: A magnet and a unipolar Hall-effect sensor IC mounted on a drug dispensing drawer provide open or close position information
