(Proximity or Presence Sensing)
From this Article:
Capacitive proximity sensors are used for non-contact detection of metallic objects & nonmetallic objects (liquid, plastic, wooden materials and so on). Capacitive proximity sensors use the variation...
(Proximity or Presence Sensing)
From this Article:
Inductive proximity sensors are used for non-contact detection of metallic objects. Their operating principle is based on a coil and oscillator that creates an electromagnetic field in the close...
(Proximity or Presence Sensing)
From this Article:
Magnetic proximity sensors are actuated by the presence of a permanent magnet. Their operating principle is based on the use of reed con-tacts, whose thin plates are hermetically sealed in a glass...
(Proximity or Presence Sensing)
From this Article:
These sensors use light sensitive elements to detect objects and are made up of an emitter (light source) and a receiver. Four types of photoelectric sensors are available.
Direct Reflection...
