Inductive Proximity Sensors: Overview, Features, and Applications
Inductive proximity sensors are non-contact sensors that detect metal objects within a specific range using electromagnetic fields. These sensors are widely used in industrial automation, manufacturing, and motion control systems for object detection, positioning, and counting applications.
How Inductive Proximity Sensors Work?
Inductive sensors generate an oscillating electromagnetic field at their sensing face. When a metal object enters this field, eddy currents are induced in the metal, which dampens the oscillation. This change in oscillation is detected by the sensor's circuit, triggering an output signal.
Types of Inductive Proximity Sensors
Shielded (Flush) Sensors
Electromagnetic field is concentrated at the front.
Can be embedded in metal surfaces.
Shorter sensing distance but better protection.
Unshielded (Non-Flush) Sensors
Electromagnetic field extends farther.
Cannot be embedded in metal surfaces.
Longer sensing range.
Analog Output Sensors
Provide a continuous signal proportional to the distance of the detected object.
Digital Output Sensors
Switches between ON/OFF states when an object is detected.
High-Temperature Sensors
Designed for extreme industrial environments.
