If you are required to select a sensor to detect an aluminum part and you need the a very narrow sensing field, then you would choose an unshielded inductive sensor.

Question

Quizplus · Accepted Answer

Shielded (or embeddable) inductive sensors are designed to have a more focused and narrow sensing field compared to unshielded (non-embeddable) inductive sensors, making them more suitable for applications requiring precise detection in a confined area.
