Essential details：PR6424/000-030+CON021 8mm Eddy Current Sensor
The PR6423/014-140+CON021 8mm eddy current sensor is a sensor for the measurement of physical quantities. A few things can be inferred from the name:
PR6423/014-140: This part may be the model or number of the sensor to identify a specific sensor design or specification.
CON021: This may be the type or number of a connection or interface that indicates how the sensor connects to an external device or system.
8mm: This indicates a certain size or measurement range of the sensor, which may be the diameter of its induction coil or other critical dimensions.
Eddy current sensors: Eddy current sensors are commonly used to measure the distance, displacement, thickness or material properties of metal objects. They work based on eddy current effects, which create eddy currents in a metal object when the sensor is near it, changing the electrical properties of the sensor. By measuring these changes, the distance between the object and the sensor or other relevant parameters can be determined.
Eddy current sensors are typically characterized by high accuracy and fast response and are suitable for a variety of industrial automation and control applications. They can measure tiny shifts or thickness changes and provide reliable measurement results.

PR6424/000-030+CON021 8mm Eddy Current Sensor
The working principle of eddy current sensor is based on eddy current effect. When the sensor approaches a metal object, eddy currents are generated on the surface of the object. This eddy current interacts electromagnetically with the sensor’s measuring coil, causing a change in the coil’s electrical properties, such as impedance. Eddy current sensors measure these changes to infer the distance, displacement, thickness, or other relevant parameters between the metal object and the sensor.
Specifically, eddy current sensors typically contain a high-frequency oscillator and a measuring coil. The high-frequency oscillator generates a high-frequency magnetic field that induces eddy currents on the surface of a metal object when the sensor is near it. This eddy creates a reverse electromagnetic field that interacts with the sensor’s measuring coil, changing the inductance or impedance of the coil.
The size of the eddy current is related to the conductivity, permeability, shape, size of the metal object, and the distance between the sensor and the object. Therefore, by measuring the change in the electrical characteristics of the coil, the distance between the metal object and the sensor or other relevant parameters can be inferred.
Eddy current sensor has the advantages of high precision, fast response and non-contact measurement, so it is widely used in industrial automation, material testing, displacement measurement and other fields. They can be used to measure the thickness, displacement, vibration, speed and other parameters of metal objects, providing reliable measurement data for industrial control and automation.
