Describe the working principle of inductive sensors.

Inductive sensors use a coil to generate an electromagnetic field and detect metal objects. The sensor measures the change in the electromagnetic field when a metal object approaches it. Signup and view all the answers

How do capacitive sensors differ from inductive sensors in terms of the type of objects they can detect?

Capacitive sensors, unlike inductive sensors, are used to detect non-metal objects by measuring the change in capacitance between a sensor and an electrode. Signup and view all the answers

What is the primary function of a rotary encoder in machine design?
