III. Characteristics and Advantages
I. What are Contact Sensors?
Contact sensors are electronic devices capable of sensing the contact or proximity status of objects. They generate electrical or control signals by detecting physical contact between objects and the sensor, enabling various automation and safety control functions.
II. Operational Principles
Contact sensors operate based on different technologies, including resistance, capacitance, and inductance. The most common type is resistive contact sensors, which detect contact status by measuring changes in resistance when an object touches the sensor. Capacitive and inductive sensors utilize changes in capacitance or inductance to achieve similar detection functions.
