True or False: Inductive Proximity Sensors are suitable for detecting plastic bottles on a conveyor.

Inductive proximity sensors operate based on the principle of electromagnetic fields to detect the presence of metallic objects. They work by generating an oscillating magnetic field and sensing changes in this field when a metal object enters it. Since plastic is non-metallic, inductive proximity sensors are generally ineffective for detecting non-metallic materials like plastic bottles.

Plastic does not have the necessary properties to disrupt the electromagnetic field generated by these sensors. Therefore, they cannot reliably detect plastic bottles on a conveyor, making the statement false. The other options suggest circumstances under which detection might occur, but they do not align with the fundamental functioning of inductive sensors which are specifically designed for metallic detection.
