SKU 9049 is an N35SH neodymium sensor disk magnet measuring 6 mm in diameter × 2.5 mm thick. It is diametrically magnetized, placing the north and south poles on opposite sides of the curved circumference. This pole orientation and its 150°C maximum operating temperature suit rotational sensing, encoders, position detection, switching, instrumentation, and high-temperature assemblies.

Design notes for diametrical sensor magnets
Confirm the circumferential pole orientation, sensor axis, operating air gap, switching threshold, temperature exposure, adhesive selection, and dimensional stack-up in the final assembly. Sintered neodymium magnets are hard and brittle, so avoid impact, snap-together collisions, uneven clamping, and excessive mechanical stress.
The listed 1.74 lb pull force is a comparison value under defined contact conditions, not a guaranteed safe working load. Diametrical magnetization, air gaps, surface roughness, coating, target geometry, temperature, and shear loading affect usable force.
Use the magnet pull force calculator for preliminary screening and compare material options in the neodymium magnet grades chart. Browse our magnet catalog or submit the magnet RFQ builder for volume pricing or a custom requirement.
