FP412D250

Differential Magneto Resistor FP 412 D 250 Dimensions in mm Features Accurate intercenter spacing High operating temperature range High output voltage Signal amplitude independent of speed Compact construction Available in strip form for automatic assembly Typical applications Detection of speed Detection of position Detection of sense of rotation Angular encoders Linear position sensing Type FP 412 D 250 Ordering Code Q65412-D 250 Semiconductor Group 1 07.96 FP 412 D 250 The differential magneto resistor FP 412 D 250 is a magnetically variable resistor in Dtype InSb/NiSb semiconductor material. The MR is glued onto a ferrite substrate and is supplied in a "MICROPACK" copper/polyimide film package. The basic resistance of each of the magneto resistors is 250 Ω. The series coupled MRs are actuated by an external magnetic field or can be biased by a permanent magnet and actuated by a soft iron target.
