Position Sensors - Usage in Angle and Linear Position Measuring

Position sensors are used in a wide range of applications from industrial automation to automobile driving assistance technologies and are an essential part of modern-day equipments. The 3048L-3-103, a Hall effect sensor, is a versatile and popular option among position sensors as it provides simple and reliable data output regardless of external environmental conditions, and is cost-effective. This article will cover the application areas and the working principle of the 3048L-3-103.

Application Fields

Position sensors find applications in many industries as the primary source for measuring variables like distance, position, displacement, velocity, force and torque. The 3048L-3-103 is among the widely used position sensors for various applications due to its compact size, reliable output, and low cost.

A few of the common applications of the 3048L-3-103 include position sensors employed in automotive and aerospace rollers for measuring the actual rotational angle of the roller, for mapping the motion of robots and robot arms in industrial automation, and home and commercial automation applications like power windows.

Working Principle

The 3048L-3-103, a Hall effect sensor, is designed to measure the angular displacements accurately. It works on the principle of the Hall effect, which states that when a magnetic material is placed in a perpendicular magnetic field, an electric voltage potential exists across the material perpendicular to both the application of the magnetic field and the direction of current flow.

The 3048L-3-103 has a built-in integrated circuit (IC) and a Hall element. When the sensor is exposed to a magnetic field, the output of the Hall element is converted into a voltage potential, which is in turn amplified by the built-in IC to provide an amplified voltage at the output, proportional to the magnetic flux density, referred to as a Hall voltage or output. This output is then used to measure angular displacement, linear position, force or torque.

The sensor has several advantages over its competitors. It can accurately measure angular displacement over a full 360° range, uses low power and requires very little external space or components for its operation. Also, its low-cost and minimal size makes it a highly attractive option for many applications.

Conclusion

The 3048L-3-103 Hall effect sensor is widely used for measuring linear and angular positions across a variety of industries. Along with its miniaturized size, it is very cost-effective, accurate, and reliable. It works on the principle of the Hall effect, and its output is proportional to the flux density of the magnetic field.
