N35SH Neodymium Sensor Rod Magnet 4 × 8 mm – SKU 9017

SKU 9017 is an N35SH neodymium sensor rod magnet measuring 4 mm in diameter × 8 mm long. It is axially magnetized, placing the north and south poles on the two circular end faces. Its compact cylindrical geometry and 150°C maximum operating temperature suit sensors, position detection, switching, encoders, instrumentation, and high-temperature assemblies.

Design notes for sensor applications

Confirm pole orientation, operating air gap, sensor 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 3.73 lb pull force is a comparison value under defined contact conditions, not a guaranteed safe working load. Air gaps, surface roughness, coating, thin target steel, temperature, and shear loading can reduce usable force.

Use the magnet pull force calculator for preliminary magnet-to-steel 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.
