N35 Neodymium Disk Magnet 5 x 3 mm Axial – SKU 9809

SKU 9809 is an N35 neodymium disk magnet measuring 5 mm diameter × 3 mm thick for Hall-effect, reed-switch, AMR/TMR, proximity, and position-sensing applications. Axially magnetized through the 3 mm thickness, it offers more magnetic volume than an ultra-thin sensor disk while retaining a compact cylindrical form.

Sensor design considerations

The listed surface-gauss and pull-force values do not by themselves define sensor performance. For a magnetic sensor, specify and validate the field magnitude and orientation at the actual working gap. Mechanical offset, nearby ferromagnetic material, temperature, and tolerance stack-up can change the field seen by the sensor.

See How Sensor Magnets Work for Hall, TMR, AMR, and rotary-sensing guidance. Use the Magnet Field Distance Calculator for preliminary gap analysis, or browse Sensor Magnets to compare stock sizes.

Procurement and custom sensor magnets

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