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 Do not press two or more products together against their 12 magnetic forces. MBH781 (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 temperature versions of up to 150 C are available on Fig.1 Simplified outline (SOT453B). request. QUICK REFERENCE DATA SYMBOL PARAMETER MIN. TYP. MAX.
