GMRB6

Giant Magneto Resistive Position Sensor Version 2.0 GMR B6 This angle sensor is based on the Giant Magneto Resistive (GMR) technology. It is outstanding for the huge tolerances it offers to the user in assembly. 2.6 max 10˚ max Features GMR sensor in SMD package Sensitive to the direction, not to the intensity of the magnetic field Constant TC of basic resistance R and magneto resistance ∆R Applications Rotation and linear sensing with large airgaps Angle encoders Contactless potentiometers Incremental encoders Pin Configuration 6 3 B 2.9 ±0.1 1.9 0.6 +0.1 -0.05 6 5 4 2˚ ... 30˚ 1.1 max 0.08 ... 0.15 0.1 ±0.3 A 10˚ max 0.1 max M 1 2 3 0.2 0.35 ±0.15 0.3 -0.05 +0.1 0.25 M B 0.20 A Reflow soldering 0.8 0.3 1 4 R1 R3 0.5 0.45 OHS00429 0.9 R2 R4 1.2 3 Directions of internal magnetization GPW06957 2/5 Dimensions in mm 6, 3 5 (= 2) 1, 4 Type GMR B6 supply ground GMR bridge access Marking B Ordering Code Q62705-K5004 Data Sheet 1 2000-07-01 1.3 ±0.1 GMR B6 The GMR B6 is an angle sensor based on sputtered metallic multilayer technology. 4 resistors are monolithically integrated on 1 chip. They can be used as a fullbridge or, if 2 external resistors are added, as 2 halfbridges. The outstanding feature of this magnetic sensor is the fact, that it is sensitive to the orientation of the magnetic field and not to its intensity as long as the field is in a range between 5 … 15 kA/m. This means, the signal output of this sensor is ind...
