DESCRIPTION handbook, halfpage The KMI15/2 sensor detects (rotational) speed and (1) reference mark detection of magnetized targets . The sensor consists of a magnetoresistive sensor element, a signal conditioning integrated circuit in bipolar technology and a magnetized ferrite magnet. The frequency of the digital current output signal is proportional to the rotational speed of a gear wheel. CAUTION 12 Do not press two or more products together against their MBH780 magnetic forces. (1) The sensor contains a customized integrated circuit. Usage in hydraulic brake systems and in systems with active brake control is forbidden. For all other applications, higher Fig.1 Simplified outline (SOT453A). temperature versions of up to 150 C are available on request. QUICK REFERENCE DATA SYMBOL PARAMETER MIN. TYP. MAX.
