An inductive sensor is a type of proximity sensor that detects metallic objects without physical contact. It operates using an oscillating electromagnetic field, which changes when a metal object enters its range. This change is then converted into an electrical signal, allowing the sensor to trigger an action, such as activating a machine or alerting a system. These sensors are commonly used in industrial applications, such as in automated manufacturing and robotics, due to their reliability and durability. They can detect various types of metals, making them versatile for different environments, including factories and warehouses.
