lähestymissensorityypit refers to the different categories of proximity sensors. Proximity sensors are non-contact devices used to detect the presence of nearby objects. They operate by emitting a field or beam of electromagnetic radiation (or other physical means) and looking for disturbances in the field or return signal caused by the presence of an object. The main types are based on their sensing technology.
Inductive proximity sensors detect metallic objects. They work by generating a high-frequency electromagnetic field from an
Capacitive proximity sensors can detect both metallic and non-metallic objects. They work by creating an electrostatic
Optical proximity sensors, also known as photoelectric sensors, use light to detect objects. They typically consist
Ultrasonic proximity sensors use sound waves to detect objects. They emit a pulse of high-frequency sound and
