What type of objects do Capacitive Proximity Sensors typically detect?

Capacitive Proximity Sensors are designed to detect a wide variety of objects, which is why the correct answer is that they can detect both metallic and non-metallic materials. These sensors work by measuring changes in capacitance in an electric field created by the sensor. When an object enters this field, it alters the capacitance, allowing the sensor to identify its presence.

This versatility is particularly useful in various applications where different types of materials need to be detected. For instance, capacitive sensors can sense liquids, plastics, wood, and even the presence of human fingers, in addition to metal objects. The ability to work with diverse materials makes these sensors widely applicable in automation, manufacturing, and liquid level sensing.

In contrast, the other options imply a limitation in the types of materials that can be detected, which doesn't reflect the actual capabilities of capacitive sensors. They do not restrict detection to either metallic or organic materials exclusively, highlighting their broad functionality in material sensing across various contexts.
