Frequently Asked Questions (FAQs)
1. How does a capacitive proximity sensor work?
Capacitive proximity sensors work by detecting changes in capacitance between the sensor and an object. Factors such as distance and the size of the object will affect the amount of capacitance. The sensor simply detects any changes in capacity generated between the two.
2. Where are capacitive proximity sensors used?
When an object is present, that changes the capacitance value and registers as the presences of the object. Capacitive proximity sensors are useful in detecting a wide range of objects. The easiest types of objects to detect are ones with a high density (such as metals) or a high dielectric constant (i.e. water).
3. What is capacitive based sensor?
A capacitive sensor is an electronic device that can detect solid or liquid targets without physical contact. To detect these targets, capacitive sensors emit an electrical field from the sensing end of the sensor. Any target that can disrupt this electrical field can be detected by a capacitive sensor.
4. What is the difference between inductive and capacitive proximity sensors?
Inductive proximity sensors are used for non-contact detection of metallic objects. Where Capacitive Proximity Sensors are used for non-contact detection of both metallic and nonmetallic objects such as liquid, plastic, paper and more.
