An (often referred to in German technical contexts as induktiver Aftaster or induktiver Näherungsschalter ) is a non-contact electronic sensor used to detect the presence of metallic objects. It operates based on the principle of electromagnetic induction and is widely employed in industrial automation, robotics, and manufacturing.
Inductive proximity sensors work on the principle of electromagnetic induction. When an object made of a conductive material, such as metal, enters the sensor's detection range, it disturbs the magnetic field generated by the coil. This disturbance causes a change in the sensor's impedance, which is measured by the sensor's electronics. The sensor then converts this change into a digital or analog signal, indicating the presence or distance of the object. induktive aftastere
Inductive proximity sensors (induktive Aftaster) are essential tools in modern automation for reliable, high-speed, non-contact detection of metallic objects. Their robustness, long life, and simple operation make them preferable over mechanical switches in dusty, wet, or high-cycle environments. However, designers must account for material sensitivity and limited range when integrating them into a system. An (often referred to in German technical contexts
There are several types of inductive proximity sensors, including: When an object made of a conductive material,
