DESCRIPTION
Pin Assignments Either north or south pole of sufficient strength will turn the output on. While the magnetic flux density (B) is larger than operate point Bop(s), the output1 will be turned on (low), the output is held until B is lower than release point Brp(s), then turned off (high). While the magnetic flux density (B) is larger than operate point Bop(n), the output2 will be turned on (low), the output is held until B is lower than release point Brp(n), then turned off (high).
