The KSY 46 is a MOVPE
1)
Hall sensor made of monocrystalline GaAs-material, built into
a SMT package (MW-6). The sensor is outstanding for its high magnetic field sensitivity
and its very low temperature coefficients. While the sensor is operated with constant
current, the output Hall Voltage is directly proportional to a magnetic field acting
prependicular to the surface of the sensor. The 0.35
0.35 mm
2
chip is mounted onto a
non-magnetic leadframe.

Connection of a Hall Sensor with a Power Source
Since the voltage on the component must not exceed 10 V, the connection to the
constant current supply should only be done via a short circuit by-pass. The by-pass
circuit-breaker shall not be opened before turning on the power source. This is to avoid
damage to the Hall sensor due to power peaks.
