*1. BOP: Operation point
BOP is the value of magnetic flux density when the output voltage (VOUT) changes after the magnetic flux density applied
to the S-5725 Series by the magnet (S pole) is increased (by moving the magnet closer).
VOUT retains the status until a magnetic flux density of the N pole higher than BRP is applied.
*2. BRP: Release point
BRP is the value of magnetic flux density when the output voltage (VOUT) changes after the magnetic flux density applied
to the S-5725 Series by the magnet (N pole) is increased (by moving the magnet closer).
VOUT retains the status until a magnetic flux density of the S pole higher than BOP is applied.
*3. BHYS: Hysteresis width
BHYS is the difference between BOP and BRP.
Remark The unit of magnetic density mT can be converted by using the formula 1 mT = 10 Gauss.
