描述
MG Series, Alnico V cast cylinderical magnet, 31,75 mm W x 6,35 mm Dia. [1.25 in W x 0.25 in Dia.].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.
特性
·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
应用
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 RPMMedical:
·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
