SS351AT

The SS351AT is a high-performance magnetic sensor produced by Honeywell Sensing and Productivity Solutions, designed for a variety of applications that require precise magnetic field detection. This sensor is part of the Hall-effect sensor family, which operates based on the principle of the Hall effect, where a voltage is generated perpendicular to both the magnetic field and the current flow in a conductor.

Key Features:

1. Type and Functionality:

   • The SS351AT is a unipolar Hall-effect sensor, meaning it activates in the presence of a magnetic field of a specific polarity. It is designed to detect the presence or absence of a magnetic field, making it ideal for applications such as position sensing, speed detection, and proximity sensing.

2. Operating Voltage:

   • The sensor typically operates within a voltage range of 4.5V to 24V, allowing for flexibility in various electronic designs and applications.

3. Output Type:

   • The SS351AT provides a digital output, which means it switches between high and low states based on the magnetic field's presence. This output is compatible with various microcontrollers and digital systems, facilitating easy integration into electronic circuits.

4. Sensitivity:

   • The sensor features a high sensitivity level, allowing it to detect weak magnetic fields. This makes it suitable for applications where precise detection is crucial.

5. Temperature Range:

   • The SS351AT is designed to operate effectively across a wide temperature range, typically from -40°C to +85°C. This robustness makes it suitable for use in harsh environments.

6. Package and Mounting:

   • The sensor is available in a compact, surface-mount package, which is advantageous for space-constrained applications. Its small footprint allows for easy integration into various devices and systems.

7. Applications:

   • The SS351AT is widely used in automotive applications (such as position sensing for throttle and transmission), industrial automation (for detecting the position of moving parts), consumer electronics (like door and lid position sensing), and security systems (for detecting the opening of doors and windows).

8. Reliability:

   • Honeywell's SS351AT is designed for high reliability and durability, ensuring long-term performance in demanding applications. Its solid-state design means it has no moving parts, reducing wear and tear over time.

Conclusion:

The SS351AT from Honeywell Sensing and Productivity Solutions is a versatile and reliable magnetic sensor that excels in various applications requiring precise magnetic field detection. Its combination of high sensitivity, wide operating voltage, and robust temperature range makes it an excellent choice for engineers and designers looking to implement effective sensing solutions in their projects.
