Advanced Hall Sensors (AHS)
Hall sensors are used in a variety of applications.
An exhaustive list would be: automotive, elevators, automated teller machines, equipment fans, vending machines, mail sorters, joysticks, door interlocks, disk drives, automatic door openers, cameras, copiers, sewing machines, washers, dryers, etc.
AHS 2-DEG do not wear out and are unaffected by dirt and other contaminants, allowing ease of use where optical sensing is not practical. The small size, durability, and low cost make the 2-DEG elements an ideal choice for difficult applications. The AHS 2-DEG sensors are ideally suited for very wide temperature range and extreme of temperatures applications (-200°C to +200°C).
The AHS sensors are designed to meet the most rigorous requirements for accuracy, repeatability and high (low)-temperature capability for the harshest automotive applications as well as for exotic cryogenic applications.
Linear Hall sensors can be used in for the same applications as Hall Switches* and Hall Latches*. Providing more sophisticated switching electronics or analog data for:
multiple air gap alarms
measuring position etc...
*In switching configurations (see graph), the voltage is amplified, then processed through a Schmitt trigger and an output transistor, which supplies an open-collector output that turns on and off at specific magnetic flux densities.
How to Use
When the Hall-Effect is combined with circuit technology, many useful magnetic sensing products are possible.
AHS can design and produce miniature circuit boards by automated pick-and-place assembly methods for anciliary electronics to enhance the Hall chip's capabilities.
