N35SH Diametric Sensor Magnet 4 × 2.5 mm, 3° Max Deviation – SKU 9083

N35SH neodymium sensor magnet, 4 mm diameter × 2.5 mm thick, Ni-Cu-Ni plated and diametrically magnetized. Listed as 100% sorted with a maximum 3° angle deviation. SKU 9083.

Diametric magnetization runs across the diameter, placing opposite poles on opposing sides of the curved surface. Use this field orientation when evaluating a compact position or rotary sensing assembly.

Design and assembly guidance

The listed maximum 3° angle deviation describes magnet sorting; it does not establish the accuracy of a completed sensor system. Validate sensor alignment, working gap, mechanical runout and field strength at the actual sensing location. A listed surface field is a reference, not the field at every distance.

The listed maximum magnet temperature is 150°C. Allowable operation depends on the magnetic circuit, opposing fields and required performance. Validate the complete assembly at its intended temperature and check adhesives and housing materials against their own limits.

Protect the brittle magnet and plated surface during handling. Provide clearance instead of forcing an interference fit. Listed pull force is a comparison value rather than a safe working load; air gaps, target steel and load direction affect actual retention.
