Inductive sensors are non-contact electronic devices used to detect the presence or absence of metallic objects. Widely applied in automation, manufacturing, and robotics, these sensors operate by generating an electromagnetic field and detecting changes caused by metallic targets. Key features include high precision, durability, and resistance to harsh environments like dust, oil, or vibration. Common types include proximity sensors, which are used for position detection, and inductive encoders for motion control. Typical products in this category include cylindrical inductive sensors (e.g., M8/M12 form factors), rectangular slot sensors for object counting, and high-temperature variants for industrial furnaces. Advanced models offer adjustable sensitivity, IO-Link communication, or ATEX certification for explosive atmospheres.
