Position sensors are designed to measure position or motion of a mechanical object. Angle and linear position sensors are two of the most commonly used types of position sensors. In this article, we will discuss the application field and working principle of the 421SL10K position sensor.The 421SL10K is a linear position sensor that uses a Hall effect technology to measure the linear position. It uses the Hall effect to measure the magnetic field created by a potentiometer that is used to adjust the linear position. The potentiometer is connected to a slider which can be adjusted to change the magnetic field at the sensor and thus the output signal.The 421SL10K can be used in a variety of applications such as monitoring the position of a production line, measuring linear displacement of a machine element, and providing feedback to a closed loop system. It can also be used to measure relative position or absolute distance of the potentiometer measurement system. The working principle of the 421SL10K is based on the Hall Effect. The Hall Effect is a fundamental effect in which an electric current flows transversely to an applied magnetic field. This effect occurs when an electric current is applied to a material that has a magnetic field applied to it. When the current is applied, the electrons in the material experience a Lorentz force which causes the charges to drift apart from their rest location. This creates an electric current perpendicular to the applied magnetic field. The electric current that is produced is proportional to the applied magnetic field.The Hall effect sensor contains two main components, the Hall Plate and the circuitry. The Hall Plate is a flat disk made of a conductor containing a magnetic field. The second component is the associated circuitry which measures the output voltage generated by the Hall Plate. The circuit of the sensor contains a reference voltage source, a series of switching components, and a set of output transistors. The voltage source is used to provide a stable voltage to the circuit. The switching components control the selection of which output transistors will be used to measure the Hall effect signal. The output transistors will then measure the Hall signal and provide the output voltage proportional to the magnetic field.The 421SL10K is a linear position sensor which means that the output voltage is proportional to the magnetic field generated by the potentiometer. This enables the sensor to provide the relative position or the absolute distance of the object being measured in its output voltage.The 421SL10K transforms the output voltage from the Hall effect sensor into a linear position. This is done by amplifying the Hall effect signal and then applying a mathematical relation between the Hall voltage and a linear position value. This provides a linear output voltage proportional to the position sensed by the Hall effect.In conclusion, the 421SL10K is an angle and linear position sensor that uses Hall effect to measure magnetic fields created by potentiometers. It is capable of providing an accurate measure of the relative position or absolute distance of an object being measured. This position sensor is widely used in various applications such as production line monitoring, and providing feedback to a closed loop system.
