Linear Hall Effect Sensor 49e Oh49e Ss49e Hall Element In Pakistan

SS49E / 49E Linear Hall-Effect Sensor – Analog Magnetic Field Detection

The SS49E is a high-sensitivity linear Hall-effect sensor that outputs an analog voltage in response to the strength and polarity of a magnetic field. Designed for precision and stability, it is ideal for applications like motor control, position sensing, current sensing, and magnetic code detection.

📦 Package Includes:

• ✅ 1 x SS49E Linear Hall Effect Sensor (also known as 49E / OH49E / A3144 Analog Variant)

🛠️ Key Features:

• 📏 Analog Output: Voltage varies linearly with magnetic field strength

• 🧭 North/South Pole Detection: Distinguishes polarity and strength

• ⚙️ Wide Voltage Range: Operates from 2.3V to 10V

• ⚡ Low Power Consumption: Draws only ~4–8mA (depending on Vcc)

• 🌡️ Temperature Range: -40°C to +85°C

• 🔧 Solid-State Reliability: No mechanical wear or contact bounce

• 📶 High Sensitivity & Low Noise Output: No external filtering required

🧪 Typical Applications:

• 🌀 Motor Control & Speed Sensing

• 🧲 Rotational Position Detection

• 💡 Magnetic Code Reading

• ⚡ Current Flow Detection in Wires

• 🚪 Door Position Sensing

• 🔍 Ferrous Metal Detection

• 🖲️ Joystick and Linear Position Feedback

📌 Pinout Configuration (Flat Face with Label Side Up):

⚙️ How It Works:

• When no magnetic field is present, the output voltage is ~½ of Vcc (e.g., ~2.5V for 5V supply).

• Bringing the South Pole of a magnet near the sensor increases the voltage toward Vcc.

• Bringing the North Pole near decreases the voltage toward GND.

• Output is continuous and linear, making it perfect for analog feedback systems.

💻 Microcontroller Compatibility:

• Compatible with Arduino, ESP32, Raspberry Pi, STM32, and more

• Connect Vout to an analog input pin

• Ideal for ADC-based (Analog to Digital Converter) measurements

• Can also be interfaced with comparators (like LM393) for threshold-based digital outputs

🧰 Example Use Case: Motor Rotation Sensing

Mount a small magnet on a rotating shaft and place the SS49E nearby. As the magnet rotates, the sensor detects the change in magnetic field and outputs a varying voltage. By analyzing this waveform using an ADC pin on an Arduino, you can determine speed, position, and direction.

🧠 Pro Tips:

• 🔧 Mounting is critical – the face with the printed label is the active sensing surface

• 🎯 Calibrate your sensor for 0V baseline using code if needed (subtract zero offset)

• 🧲 Keep ferromagnetic objects away to avoid interference in readings

🔁 Alternative Options:

• A3144 Digital Hall Effect Sensor – for on/off magnetic detection

• LM393 Comparator Module – for adjustable threshold digital triggering

• Current Sensor Modules (ACS712/ACS758) – for dedicated current measurements
