HK401 Datasheet | SZWKW

HK401 High Voltage Hall Effect Switch Sensor Introduction HK401, designed with Bipolar technology, includes on-chip Hall element voltage generator, a voltage regulator for operation with supply voltages of 3.8 to 60V, reverse voltage protection, temperature pensation circuitry, small-signal amplifier, Schmitt trigger and an open-collector output. The sensor is designed to respond to North and South poles. While the magnetic flux density(B) is larger than operate point Bop, the output will be turned on with low output level. Then the output is held until the magnetic flux (B) is lower than release point Brp. The output will be turned off with high output level. HK401 offers a variety of packages, including TO-92, SOT-23. All packages are RoHS pliant.
