The position sensor KSY 13 is an ion-implanted Hall generator made of mono-crystalline
GaAs material. Enclosed in a miniature package (SOT 143), it is suitable for surface
mounting (SMT).
If the sensor is operated with a constant supply current, the output Hall voltage is directly
proportional to a magnetic field acting upon the sensor. This sensor is outstanding for its
high magnetic field sensitivity and very low temperature coefficient.
The active area of the GaAs chip is approx. 0.2 mm
×
0.2 mm and is placed approx.
0.3 mm below the plastic surface of the package. The chip carrier is softmagnetic.
