N52 offers higher magnetic energy than N35, which can be useful where designers need strong output from a small package. The tradeoff is a lower listed maximum operating temperature for this part, so thermal conditions should be checked carefully in the final assembly.
The listed pull force is a reference value under defined contact conditions. Air gap, steel thickness, contact area, surface finish, temperature, and load direction all affect real-world performance. Use the Magnet Pull Force Calculator for preliminary screening and browse N52 neodymium magnets for related high-energy parts.
