Pepperl+fuchs photoelectric sensor (pair type)
|
The transmitter and receiver of the P+F photoelectric sensor are located in two separate shells. The light transmitted by the transmitter is directly received by the receiver. If the object blocks the beam, the switch function triggers.
The photoelectric sensor is usually used for long distance detection, with good stability and strong energy. The characteristics of the photoelectric sensor also determine that it is suitable for the dusty and dirty industrial environment.

Product characteristics of P+F photoelectric switch industry:
In the development of a new generation of VISOLUX photoelectric sensors, Begaff defined a series of product characteristics to integrate different types of sensors. These industry characteristics, even in the most difficult applications, are reliable and moderately priced, such as VISO+.
The characteristics of VISO+:
High brightness LED
|
Green LED power indicator lamp
|
High resistance to ambient light
|
Rich output (e.g. "4-in-1" or AS-Interface 2.1 bus)
|
Automatically prevent interference from light.

Pepperl+fuchs photoelectric sensor (reflecting plate type)
|
Reflective plate P+F photoelectric sensor, the path of light is between a sensor and a special reflector. When an object blocks the beam, it will be detected by the sensor. Compared with diffuse reflection photoelectric sensor, the typical reflective plate sensor provides a longer detection distance. In some units, the visible red LED is used to assist in installation and alignment of reflectors. A cube reflector will accurately return the light energy to the receiver on the parallel axis.
|
The reflective plate type P+F photoelectric sensor has the following characteristics:
Polar filtering: If a flashing object is blocked in front of a reflective plate sensor, the polar filtering function eliminates possible errors. The polarity filter can ensure the error detection of the flash object or the surface highly reflective substance.
Transparent object detection: Transparent object detection sensor is a special reflective plate photoelectric sensor, it can detect ordinary reflective plate sensor can not detect transparent objects. When detecting transparent objects, sensors can detect tiny differences by using low hysteresis circuits. Transparent object detection sensors use polar filters on both transmitters and receivers to reduce the error rate caused by object reflection.
Pepperl+fuchs diffuse photoelectric sensor (reflective type)

The emitted light of the transmitter is scattered at any angle after being detected on the detector. When the receiver receives some of the light (when the received light is stronger than the switch threshold), the switch triggers and the object is detected. Generally speaking, the factors related to the detection distance are: the color, size and gloss of the detection substance. The actual detection distance of the sensor is based on the "white test board". The whiteboard has a reflectivity of 90%, which is usually regarded as a "standard detector". Dark or non-smooth objects usually have low reflectivity; therefore, in detecting such objects, the sensitivity of the sensor must be increased or the sensor must be moved closer to the object. At this point, we must pay attention to the background object is brighter than the detection object, the result may detect the background object (and ignore the actual detection object).
