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 applications. They are ideal for hand-held equipment like cell phones and palmtop computers, offering superior reliability and ease of manufacturing by replacing reed switches. Their unique clocking scheme significantly reduces average operating power requirements.
