Giant magnetic resistor sensor for contactless detection of rotary/linear motion of relatively movable parts has stationary part with GMR cell of variable GMR resistance, magnet element rotary part

摘要

The giant magnetic resistor rotation angle sensor has stationary and rotary parts. The stationary part has at least one giant magnetic resistor cell (10') of a variable giant magnetic resistor or GMR resistance (R10) and the rotary part (8) is at least one magnet element (5). They are movable arranged relative to each other with a gap (6) between them and the variable giant magnetic resistor resistance is arranged in a resistance network.
