What is a characteristic of Inductive Proximity Sensors?

• A. They detect changes in temperature
• B. They sense metallic objects
• C. They measure light intensity
• D. They operate solely on magnetic fields

Answer: (B)

Inductive proximity sensors are specifically designed to detect metallic objects without direct contact. They function by generating an electromagnetic field and can sense changes in this field caused by the presence of conductive materials, such as metals. This characteristic makes them particularly useful in industrial applications for detecting the position of metal components, ensuring proper functioning of machinery, and enhancing automation processes. The other options involve different functionalities not associated with inductive proximity sensors. For instance, temperature detection relates more to temperature sensors, measuring light intensity pertains to photoelectric sensors, and operating on magnetic fields is typically associated with magnetic sensors. Thus, the ability to sense metallic objects is a defining feature of inductive proximity sensors.
