CYD41 High Sensitive Hall effect Switch
IC for high temperature |
 |
CYD41 Series high sensitive Hall Effect
switch IC 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. ICs can convert the
changeable magnetic field signal into digital voltage output.

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 at the leads; keep it
lower in a short time to guarantee good soldering quality.
