N40 Neodymium Magnet disc : Packs of 30mm OD x 3mm H with 3M VHB Self Adhesive
Abbreviations and Conventions used Storewide
All Dimensions are in Metric Scale (mm); Conventions and abbreviations used throughout the Store:
L : Length | OD : Outer Dia | ID : Inner Dia | W : Width | H : Height | T : Thickness (also Height) | CS : Countersunk | G : Gauss
The terms Force or Pull Force are used interchangeably throughout the store and refer to the maximum observable or tested force against a 10mm thick grinded finish mild steel plate. The pull force will depreciate with thinner plates or sheets. The Pull force or Force is expressed in lbs, Kg or N.
[10N (Newtons) = approx 1 Kg = approx 2.2 lbs Pull Force]
Dimensional tolerances
Typical dimensional tolerances for sintered magnets (depending on size and complexity are as follows
Neodymium (NdFeB) : ± 0.1
Samarium (SmCo) : ± 0.1
Ferrite / Ceramic : ± 0.2
AlNiCo : ± 0.01
