Product Description
Product Overview
The A3213 and A3214 are ultra-sensitive, pole-independent Hall-effect switches with a latched digital output, designed for low-power, battery-operated equipment. They offer superior reliability and ease of manufacturing by replacing reed switches, eliminating the need for signal conditioning. Their chopper stabilization technology ensures improved stability and reduced offset voltage.
