    Tips: What is an unshielded proximity sensor?

    ATO unshielded proximity sensor, also known as a non-shielded or unshielded inductive sensor, is a type of inductive sensor used to detect the presence or absence of metallic objects within a certain range without direct contact.

    Unlike shielded proximity sensors, which have a metal housing that focuses the electromagnetic field to the front of the sensor, unshielded sensors emit an electromagnetic field in a wider, more dispersed pattern around the sensing face.

    The broader detection area of unshielded proximity sensors makes them suitable for applications where a larger sensing range is required, or where the exact positioning of the object is less critical. They are typically used in environments where there is a need to detect objects from multiple directions or where installation space allows for a less focused sensing approach.

    Unshielded proximity sensors are widely used in industrial automation for tasks such as counting parts on a conveyor belt, detecting the position of machinery components, or ensuring the presence of metal objects in assembly processes. Their main advantage lies in their ability to detect objects in a broader area, though this can also make them more susceptible to interference from surrounding metal objects and require careful placement to avoid false detections.
