What is the sensing range for capacitive proximity sensors?

Good question! Capacitive proximity sensors typically have sensing ranges from about 3 to 60 millimeters, though some specialized models can detect objects up to a few centimeters away. The actual range depends on several factors:- The sensor's size and design- The material being detected (metals vs non-metals)- Environmental conditionsThese sensors work by detecting changes in capacitance and are great for detecting liquids, powders, and non-metallic materials. Unlike inductive sensors that only detect metals, capacitive sensors can detect almost any material! For specific applications, you'd need to check the manufacturer's specs since ranges vary significantly.

The sensing range for capacitive proximity sensors usually falls between 1 mm to 50 mm, depending on the model. Some high-end industrial ones can detect up to 60 mm or more. These sensors can detect not just metals but also plastics, glass, wood, and even liquids since they work on changes in capacitance. If you’re buying one, always check the datasheet for exact specs.
