Sensor arrangement for use in wheel speed sensor system for detecting wheel speed of truck, has sensitive structures with magnetoresistive conductor segments, where two segments are electrical conductive connected with one another

摘要

#CMT# #/CMT# The arrangement has a sensor (5) for detecting a magnetic field that is produced and/or modulated by an encoder (7). The sensor comprises a sensor element (Sa, Sb) with a sensitive main plane, and a magnetic unit for producing a magnetic supporting field (8) with a main magnetization direction parallel to the sensitive main plane. The sensor element has sensitive structures (6a-6d) that include magnetoresistive conductor segments, where two of the segments are aligned parallel to one another, switched in series and electrical conductive connected with one another. #CMT#USE : #/CMT# Sensor arrangement for use in a wheel speed sensor system of a motor vehicle (all claimed) e.g. truck, for detecting relative movement and/or angular displacement and/or for detecting corresponding speed of the vehicle. Can also be used for a motorcycle and a trailer. #CMT#ADVANTAGE : #/CMT# The arrangement comprises the sensor element with magnetoresistive structures without barber pole, thus manufacturing the sensor arrangement in a cost effective, compact and/or in robust manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a sensor and sensitive structure with magnetoresistive conductor segments.
