From Wearables to IoT: Slkor’s SL1609 Hall Sensor Enables Seamless Switching with Record-Breaking Efficiency

Slkor’s engineering team originates from Tsinghua University, bringing world-class expertise to one of China’s earliest developers of silicon carbide (SiC) power devices. Today, Slkor has evolved into a national high-tech enterprise integrating R&D, design, sales, and technical application services. Its culture is inclusive, open, and innovation-driven, and its “SLKOR” brand is recognized worldwide for quality and reliability. Slkor holds ISO9001 certification along with RoHS, REACH, California Proposition 65, and other international compliance credentials.

With R&D hubs in Beijing and Suzhou and a state-of-the-art lab and central warehouse at its Shenzhen headquarters, Slkor delivers three core product lines:

• Diodes & Transistors

• Power Devices

• Power Management ICs

In parallel, the company is expanding into new product categories including Hall sensors, ADCs, BMS, high-speed optocouplers, and passive crystals—serving markets from smartphones, laptops, and robotics to power tools, connected vehicles, 3C electronics, and AIoT systems. By partnering with over 10,000 global customers, Slkor is driving innovation across industries worldwide.

Beyond products, Slkor’s official website has become a knowledge and collaboration hub for the semiconductor sector, creating a digital ecosystem that supports customers, partners, and employees alike. Slkor’s long-term vision is clear: within the next 30 years, become a true global “Semiconductor Leader.”

4. Seamless Integration
The SL1609 Hall sensor easily drops into standard application circuits, enabling precise, energy-efficient position or proximity detection across consumer, industrial, and automotive products.

 

 

4.1 Application Principle

Based on magnetic-induction technology, Slkor Hall elements switch their output from high to low when exposed to a correctly oriented magnetic field. This enables precise, contact-free detection of position or movement. Because of their high sensitivity and ultra-low power consumption, Hall sensors are widely used in:

• TWS earphones & smartphones (lid or wear detection)

• Electronic locks & smart access systems

• Valve position sensing in industrial equipment

• Magnetic keyboards, digital pianos & flow meters

• Other non-contact detection applications

Why Slkor Hall Sensors Stand Out
Models such as SL1609, SL1603X, and SL1613X are ultra-low-power Hall switches designed for modern, battery-driven electronics. With a maximum output current of 5 mA, they can directly drive small signal loads like indicator LEDs or micro-switches without additional circuitry.

Example Circuit:
In a simple application, the sensor connects to a 1 kΩ resistor and LED. When a magnetic field is detected, the LED turns off—providing immediate visual feedback.

Real-World Applications That Power Everyday Life

• Smart Laptops & Tablets – Hall switches precisely coordinate with embedded magnets to enable seamless functions: the screen lights up the moment a laptop lid is opened, and tablets instantly go to sleep when their covers close.

• Wearables & Health Devices – In smartwatches, Hall sensors act as “health assistants,” detecting the strap’s magnetic buckle to confirm the device is being worn—reducing false activity readings and improving health data accuracy.

• Robotics & 3C Manufacturing – Acting as the “eyes” of robotic arms, Slkor Hall switches detect magnet positions on end-effectors with 0.01 mm accuracy, ensuring flawless chip packaging and higher yield rates.

• Industrial Automation & Logistics – In conveyor systems, Hall counting switches can detect material flow up to 2,000 times per second, integrating with PLCs for automated sorting and boosting efficiency by 30% versus manual counting.
