Induktive Aftastere Here

| Parameter | Description | |-----------|-------------| | | Typically 0.5 mm to 60 mm, depending on sensor size and target material. | | Target Material | Ferrous metals (e.g., steel) have the longest sensing range. Non-ferrous metals (e.g., aluminum, copper) have shorter ranges due to lower magnetic permeability. | | Hysteresis | Typically 5–15% of sensing distance (prevents output flutter near switching point). | | Output Types | NPN (sinking), PNP (sourcing), AC, DC, NO (normally open), NC (normally closed). | | Protection Class | Often IP67 or IP68 for harsh industrial environments. |

En er en elektronisk nærhedssensor , der detekterer metalobjekter uden fysisk kontakt. Disse sensorer er fundamentale komponenter i moderne industriel automation, da de er ekstremt robuste over for støv, snavs og fugt. Hvordan fungerer en induktiv aftaster? 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. | Parameter | Description | |-----------|-------------| | |

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. | | Hysteresis | Typically 5–15% of sensing
