Product Overview

The VCS1301 is a highly integrated, ultra-low power, omnipolar magnetic switch sensor. It combines an AMR magnetic sensor with high-precision CMOS processing circuitry in a miniature package. The CMOS circuitry features precisely controlled BOP/BRP offset voltage compensation and a push-pull output, offering an industrial operating temperature range (-40 to 125), a wide voltage supply range (1.8V to 5.5V), and nanoampere current consumption. Its omnipolar nature simplifies installation by not requiring polarity identification of the magnet. Leveraging AMR's high-speed response, the VCS1301 offers high response frequency, low power consumption, small size, and excellent temperature characteristics, making it ideal for various handheld and battery-powered applications.
