HAL58x

current output for two-wire applications
low current consumption: 5 mA ... 6.9 mA
high current consumption: 12 mA ... 17 mA
junction temperature range from 40 °C up to 140 °C.
operates from 3.75 V to 24 V supply voltage
operates with static magnetic fields and dynamic magnetic fields up to 10 kHz
switching offset compensation at typically 145 kHz
overvoltage and reverse-voltage protection
magnetic characteristics are robust against mechanical stress effects
constant magnetic switching points over a wide supply voltage range
the decrease of magnetic flux density caused by rising temperature in the sensor system is compensated by a built-in negative temperature coefficient of the magnetic characteristics
ideal sensor for applications in extreme automotive and industrial environments
EMC corresponding to DIN 40839

The HAL571 is designed for applications with one magnetic polarity and weak magnetic amplitudes at the sensor position such as:
applications with large airgap or weak magnets,
solid state switches,
contactless solutions to replace micro switches,
position and end point detection, and
rotating speed measurement
