Packing: Taped on 18 cm reel, 3K parts per reel, date code on the label.

The KSY 46 is a MOVPE¹⁾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 mm²chip 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.
