Product Description
DiodesZetex AH1903-FA-7 is a surface mount Hall Effect sensor designed for precision and reliability in electronic sensing applications. This device features chopper stabilized Hall Effect technology to provide stable and accurate switching responses to magnetic fields. It is enclosed in a compact 4-pin X1-DFN package, measuring 1.65mm in length, 1.25mm in width, and 480μm in height, making it suitable for space-constrained PCB layouts.
The sensor operates across a supply voltage range of 1.6 V to 3.6 V, allowing compatibility with low voltage digital circuits. It detects omnipolar magnetic fields, enabling it to respond to either polarity of magnets, making it versatile for a wide range of magnetic sensing needs. The device sustains reliable operation under a broad temperature range of -40°C to 85°C, suitable for demanding industrial and automotive environments.
With a supply current of only 4.3μA, the AH1903-FA-7 sensor helps minimize total system power consumption. A rapid response time of 50 microseconds allows it to quickly react to changing magnetic conditions, which is essential for motion detection, position sensing, and switching applications.
This Hall Effect sensor is RoHS-compliant and lead-free, assuring adherence to environmental standards. It is manufactured in China under strict quality controls. Utilizes chopper stabilized Hall Effect technology for accurate sensing.
Omnipolar magnetic sensing detects both north and south poles. Compact 4-pin X1-DFN surface mount package suitable for modern electronics. Wide operating temperature range from -40°C to 85°C ensures robust performance. Low power consumption with only 4.3μA supply current.
Fast 50μs response time ideal for dynamic switching applications. Lead-free and RoHS certified for environmental compliance. Ideal for automotive, industrial, and electronic equipment requiring contactless magnetic sensing.
