Ceramic Ferrite Ring Magnets
Ceramic Ferrite Ring Magnets
Ceramic Ferrite Ring Magnets are widely used in loud speakers, motors, relays, switches, pot magnets and also in conjunction with proximity meters to record speed or degrees of rotation. Large ring magnets are used inside head rollers on conveyors for tramp iron removal and also around water pipes to help prevent deposits of minerals on the inside of the pipe walls and descale the existing deposits. In stock, diameter sizes range between 27mm and 220mm and thicknesses from 5mm up to 20mm. An advantage is the high maximum operating temperature of 250 degrees Celsius. Alternative sizes can be made if required.
