Product Description
Product Overview
The AH49H is a compact and versatile linear Hall-effect sensor that operates based on magnetic fields from permanent magnets or electromagnets. Its output voltage is directly proportional to the magnetic field strength, regulated by the supply voltage. Designed for efficiency and accuracy, it features integrated low-noise circuitry, eliminating the need for external filters, and precision resistors for enhanced temperature stability. With an operating temperature range of -40C to 105C, it is suitable for commercial, consumer, and industrial applications. Available in TO-92S-3 and SOT-23-3 packages.
