In the proximity sensor category, inductive sensors, capacitive sensors, optical sensors, optical fiber sensors, fiber optics and area sensors are available.
Inductive proximity sensors work by changing their field electromagnetic due to the movement of the metal element.
Capacitive proximity sensors react to approaching its surface active (sensor field) of any material (medium).
Photoelectric proximity sensors are used to detect the object in the specified area. Detection is carried out by interrupting the light path between the transmitter and the receiver. Depending on the light path type, reflective sensors, diffuse sensors and light barriers are distinguished.
Fiber Optic Sensors are used to detect small objects in a specified area of ??operation. Detection is carried out by interrupting the light path between the transmitter and the receiver. The set includes fiber optic amplifier that allows you to set the sensitivity of the sensor.
Area sensors are dedicated to detecting the movement of the object in specific area. The scope of the sensor's operation is greater due to the presence of several light paths. Detection of objects takes place by interrupting one of these roads.
