They are designed to respond to alternating North and outh poles. While the magnetic flux density(b) is larger than operate point (Bop), the output will be turned on (Low), the output is held until the magnetic flux density(b) is lower than release point (Brp), then turn off (High). The MT1401 family provides a variety of packages to customers: OT-23/OT-89B for surface mount and TO-92 flat for through-hole mount. All packages are RoH compliant. 01/10

4 Electrical and Magnetic Characteristics Absolute Maximum Ratings Absolute maximum ratings are limiting values to be applied individually, and beyond which the serviceability of the circuit may be impaired. Functional operability is not necessarily implied. Exposure to absolute maximum rating conditions for an extended period of time may affect device reliability.
