| Hall Sensor KSY 13 Version 2.0 Features * * * * High sensitivity High operating temperature Low offset voltage Low TC of sensitivity and internal resistance * Plastic miniature package SOT 143 for surface mounting (SMT) Typical Applications * Digital speed sensors * Digital position sensors * Commutatorless DC motors Dimensions in mm Type KSY 13 (E 7502) Marking S 13 Ordering Code Q62705-K209 (taped on 18-cm reel) 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 x 0.2 mm and is placed approx. 0.3 mm below the plastic surface of the package. The chip carrier is softmagnetic.
