Magnetic Sensors - Position, Proximity, Speed (Modules) are commonly used in a wide range of applications, ranging from consumer electronics to automated industrial production processes. The 55505-00-03-C is a module specifically designed to detect the relative position of two objects using magnetic fields. In this article, we will look at the applications for this type of sensor and its working principle.

Application field

The 55505-00-03-C magnetic sensor is designed for use in applications requiring the measurement of the relative position or movement of two objects. Commonly found applications include the detection of the relative position of a movable object (such as a robotic arm) and a fixed object (such as a door). Industrial tasks include the detection of the movement of parts on a conveyor belt, the identification of faulty parts in an assembly line, and the detection of changes in product weight. Other applications include the detection of the relative movement of an encoder and a spline shaft in a printer, the detection of the relative position of instrument and table in a laboratory environment, and the mapping of the relative position of a machine component in a virtual model of the system.

The 55505-00-03-C also has applications in the detection of the relative positions of two objects in 3-D space. In this case, the sensors conventionally mounted in two fixed locations to detect the vector between them. Such sensors are used in computer-controlled manufacturing, robotics, and computer vision applications.

Working principle

The 55505-00-03-C magnetic sensor operates on the principle of detecting changes in magnetic fields. Two coils, or electromagnets, are mounted in a fixed position relative to each other, with one being the sensing element and the other being the reference element. The sensing element is connected to a circuit that produces a constant magnetic field. This magnetic field is measured by the reference element, and any change in the field is detected by the reference element and used to infer the relative position of the two objects.

The reference element in the 55505-00-03-C is an eddy-current inductance sensor. This type of sensor includes a winding of copper wire mounted in a magnetic material such as iron or steel. When a magnetic field passes through the winding, eddy currents are created in the conductor, which in turn induce a magnetic field in the material. The magnitude of this magnetic field is proportional to the current passing through the conductor, and any change in the field is detected by the reference element and used to calculate the relative movement of the objects.

The 55505-00-03-C also includes a frequency-to-digital converter, which converts the frequency of the magnetic field to a digital signal. This signal is then used to calculate the position and relative movement of the two objects. The output from the sensor is typically a voltage signal that can be read by a microcontroller, which can then be used to control the position of the object in relation to the reference point.

The 55505-00-03-C offers high sensitivity and accuracy in a compact module. This makes it an ideal choice for use in applications that require precise and reliable measurements of the relative position of two objects.
