SKU 9810 is a compact 4mm diameter × 1mm thick N35 neodymium disk magnet suited to magnetic sensing, proximity detection and compact position-sensing assemblies where a small axial field source is required. It is axially magnetized through the 1mm thickness and is assigned to Radial Magnets’ Sensor Magnets catalog.

Using This Magnet With a Sensor

For Hall-effect, reed, AMR or TMR sensing, the important design value is usually the magnetic field at the actual sensor location, not the catalog pull-force number. Field strength changes rapidly with gap, alignment and nearby steel, so validate the magnet with the intended sensor and mechanical stack-up.

Use the Sensor Magnet Design Guide to compare sensing arrangements and the Magnet Field Distance Calculator for preliminary field-versus-gap screening. To compare other stock sizes, browse Sensor Magnets.
