*1. BOPN, BOPS: Operation points

BOPN and BOPS are the values of magnetic flux density when the output voltage (VOUT) is inverted after the magnetic flux

density applied to the S-5717 Series by the magnet (N pole or S pole) is increased (the magnet is moved closer).

Even when the magnetic flux density exceeds BOPN or BOPS, VOUT retains the status.

*2. BRPN, BRPS: Release points

BRPN and BRPS are the values of magnetic flux density when the output voltage (VOUT) is inverted after the magnetic flux

density applied to the S-5717 Series by the magnet (N pole or S pole) is decreased (the magnet is moved further away).

Even when the magnetic flux density falls below BRPN or BRPS, VOUT retains the status.

*3. BHYSN, BHYSS: Hysteresis widths

BHYSN and BHYSS are the difference between BOPN and BRPN, and BOPS and BRPS, respectively.

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