Introducing our high-performance 49E Linear Hall Effect Sensor, designed for accurate and proportional magnetic field detection. This essential component offers a reliable solution for a wide range of electronic and automation projects where precise magnetic sensing is critical.

Key Features:

• Linear Output: Unlike simple ON/OFF Hall switches, the 49E provides a linear analog output voltage that varies directly with the strength and proximity of a magnetic field. This allows for more nuanced and precise measurements of magnetic pole distance.
• Wide Operating Voltage: Works efficiently with a supply voltage range of 3V to 6V, making it compatible with various microcontrollers and power sources (e.g., Arduino, Raspberry Pi, ESP32).
• Low Power Consumption: With a minimal operating current of just 5mA, this sensor is energy-efficient, perfect for battery-powered or low-power applications.
• Proximity Sensing: Ideal for applications requiring detection of magnetic pole proximity, where the output voltage changes proportionally as a magnet approaches or moves away from the sensor.
• Reliable Performance: Built for consistent and stable operation in diverse environments.
• Convenient 3-Pack: Each order includes three (3) individual 49E Linear Hall Effect Sensors, providing excellent value for multiple projects or replacements.

How it Works: The 49E Linear Hall Effect Sensor operates on the principle of the Hall effect. When exposed to a magnetic field perpendicular to its sensitive surface, it produces a voltage proportional to the strength of that field. The closer a magnetic pole gets to the sensor, the stronger the magnetic field it detects, resulting in a corresponding change in the output voltage. This analog output allows you to read varying magnetic strengths and distances.

Ideal Applications:

• Magnetic field strength measurement
• Position sensing (e.g., linear displacement, rotary encoders)
• Current sensing (with appropriate magnet setup)
• Security systems
• Motor control feedback
• Fluid level detection
• Non-contact switching where proportional response is needed
