Magnetic Sensors – Hall-Effect Linear Sensor ICs

Constructed from a thin sheet of conductive material, Honeywell linear magnetic sensor ICs generate an analog voltage output proportional to a magnetic flux perpendicular to the surface of the sheet. Quad Hall-Elements design minimizes effects of mechanical or thermal stress on output and provide a stable output (SS490/SS491).

Catalog listings include SS.
