*1.

magnetic flux density applied to the S-5713A Series by the magnet (N or S pole) is increased (the magnet is moved

closer).

*2.

magnetic flux density applied to the S-5713A Series by the magnet (N or S pole) is decreased (the magnet is moved

further away).

*3.

Remark The unit of magnetic density mT can be converted by using the formula 1 mT = 10 Gauss.
