CYD1024 HALL-EFFECT SWITCH ICs
CYD1024 Hall-effect switch is a monolithic integrated circuit, which is
composed of a reverse protector, voltage regulator, Hall voltage generator,
differential amplifier, Schmitt trigger and an open-collector output on a single
silicon chip. The switch IC can convert a changeable magnetic field signal into
digital voltage output.

Connection
This sensor has an OC (NPN) output voltage. Therefore it is necessary to connect a pull-up resistor
in value from 0.5kΩ to 10kΩ between the power supply Vcc and output pins.

Cautions:
1) It is possible that outside mechanical stress affects the operating point and the release point
of Hall-effect circuit, therefore, mechanical stress should be lessened as far as possible in
the process of assembly;
2) Pay attention to the soldering temperature (<260°C) at the leads; keep it lower in a short
time (<3s) to guarantee good soldering quality.
