The S-57B1 Series, developed by CMOS technology, is a high-accuracy Hall effect switch IC that operates with a high-sensitivity, a highspeed detection and low current consumption. The output voltage changes when the S-57B1 Series detects the intensity level of flux density. Using the S-57B1 Series with a magnet makes it possible to detect the open / close and rotation state in various devices. High-density mounting is possible by using the small SOT-23-3 package. Due to its high-accuracy magnetic characteristics, the S-57B1 Series can make operation’s dispersion in the system combined with magnet smaller.
