Micronas offers the world’s broadest range of Hall-effect sensors, which are increasingly being utilized in a variety of industrial applications, including factory and process automation; building, home, and office automation; medical applications; mobility and robotics controllers; agriculture and heavy machinery; garden and power tools; and household items such as washing machines, tumble dryers, induction cookers, and heating and cooling (HVAC) systems.
The HAL 506 is produced in CMOS technology. All sensors include a temperature compensated Hall plate with active offset compensation, a comparator, and an open drain output transistor. The active offset compensation leads to magnetic characteristics which are robust against mechanical stress effects. In addition, the magnetic characteristics are constant in the full supply voltage and temperature range. The comparator compares the actual magnetic flux through the Hall plate (Hall voltage) with the fixed reference values (switching points). Based on the reading, the output transistor is switched on or off.
The sensors are designed for industrial applications and operate with supply voltages from 3.8 V to 24 V in the ambient temperature range from –40 °C up to 150 °C.
