Magnetic Sensors for Safety and Powertrain Applications

Differential Hall ICs are designed specifically for gear tooth and magnetic pole wheel speed and timing se nsing such as crankshaft, transmiss ion orwheel-speed applic ations.

In industrial applications, tese Hall ICs may be used for rotational seed and position sensing.

For camshftposition sensing a high precision device using a chopped mono Hall cell is offering the benefit of ture power on information.
