Its flexible configuration ensures reliable, precise performance across a variety of demanding use cases. See the illustration below for details:

The SL1603SH is a high-sensitivity, omnipolar Hall effect switch sensor, part of the versatile SL1603 series. It detects both South and North magnetic poles — outputting a low-level signal when the magnetic flux density exceeds its operate point (Bop), and returning to a high-level signal once the field drops below its release point (Bep).

Engineered with a built-in temperature compensation circuit and clock logic, the SL1603SH ensures consistent, stable performance and precise switching frequency across varying conditions. Its reliability and compact design make it ideal for a wide range of civil applications and consumer electronic products. See the diagram below for a visual overview.

The SL1603SH offers full-polarity sensitivity, enabling precise detection of both North and South magnetic fields — making it a reliable choice for a wide range of magnetic sensing and control systems. Engineered for energy efficiency, it operates smoothly with a 6V supply while consuming an ultra-low 3.3μA of current, making it ideal for battery-powered devices like smartphones, tablets, smartwatches, and other portable electronics where power conservation is essential.

Designed for fast, reliable response, the SL1603SH features a 5Hz scanning frequency, ensuring quick detection and immediate feedback — perfect for applications in high-speed motion control, position sensing, and system wake-up functions. Housed in a compact, durable SOT-23 package, it delivers excellent mechanical strength, thermal stability, and complies fully with RoHS environmental standards, making it a dependable, eco-friendly solution for modern electronic designs.

The SL1603SH is a versatile, high-sensitivity Hall effect sensor widely adopted across both consumer electronics and civil applications. In smart utility meters — such as water and gas meters — it plays a crucial role by detecting magnetic field changes and converting them into precise electrical signals. This allows for accurate measurement of flow rates and consumption data, improving efficiency and reliability in modern metering systems.

In consumer electronics, the SL1603SH enhances user experience in devices like smartphones, tablets, laptops, and headphones. For example, it can detect headphone insertion, automatically switching audio output modes without user input, or enable smart wake-up and proximity detection functions in mobile devices.

With multiple magnetic field thresholds, adjustable operating frequencies, and flexible packaging options, the SL1603SH is engineered to meet the diverse demands of space-constrained, power-sensitive applications — making it a smart, reliable choice for next-generation electronic products and smart infrastructure solutions.

Beyond the SL1603SH, SLKOR offers a diverse portfolio of high-performance Hall effect sensors, including models like SLSS360–3, SLSS49E-3, SL-322B, SLOH49E-9, SLSS451A-9, SL1623SH, SLSS41F-9, and many others. These sensors are engineered to deliver precise magnetic field detection with ultra-low power consumption, catering to the growing demand for energy-efficient, high-reliability solutions across various industries.

SLKOR remains dedicated to advancing innovation in sensor technology, continuously expanding its product lineup to support the evolving needs of modern electronic applications — from smart devices and industrial automation to intelligent metering and beyond.
