Magnets for Sensor

Magnets for Sensor

We can design magnets to provide specific field strengths at a required position relative to the magnet. We can design magnets to trigger Hall Effect devices at different locations compared to the magnet that may have come with the Hall Effect device (to expand the Hall Effect capability). We can work with you to design a magnet to trigger a Reed Switch correctly (so you do not need to use the reed manufacturer test coils). Because Reed Switches have ampere-turn trigger levels instead of Gauss or Tesla values, it is not simple to convert from A-t to mT (there is no equation that can be applied for any Reed Switch device there are many variables to factor in which makes an equation impossible) but we do have a simple test method that will determine the actual required mT trigger values that can then allow a re-design using a magnet to trigger the Reed Switch at the required location in your application.

Multipole ring magnets for sensor

Multipole Ring Magnets

Multipole ring magnets are custom solutions It is always used together with Hall for speed, location sensor application .The multipole magnet magnetizing on outdiameter , on inner diameter and axial all can be available.

Diametric Disc Magnets for sensor    Axial Disc Magnets for sensor

Diametric Disc Magnets / Rod Magnets

The diametric disc or rod magnets are available with NdFeB and Ferrite. We are happy to work with you to provide your custom the magnet for your application requires.

Axial Disc Magnets / Rod Magnets

Axial disc or cylinder magnets are available in SmCo , NdFeB and Ferrite magnet per your detail application situation . With advanced modeling capabilities to determine the ideal magnet for your application, we guarantee superior performance.

If you have a magnet that works but not quite well enough we can help you get a magnet that will work as you want. And we can supply test samples to approve and then mass produce afterwards. Here to contact us: Call Us Today! 86-574-27667267  / EMAIL: info@hsmagnets.com
