9810 – N35 Neodymium Disk Magnet 4 x 1 mm Axial

SKU 9810 is an N35 neodymium disk magnet measuring 4 mm diameter × 1 mm thick for compact Hall, reed, AMR/TMR, proximity, and position-sensing applications. Axially magnetized through the 1 mm thickness, it provides a very small magnetic field source for tightly packaged sensor assemblies.

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.

Procurement and custom sensor magnets

For alternate diameters, thicknesses, grades, coatings, or production quantities, compare the Neodymium Magnet Grades Chart and use the Magnet RFQ Builder.
