Pepperl+Fuchs Sensor Wonderful Industry German Original

P+F Pepperl+Fuchs photoelectric switch proximity switch is widely used in automatic counting, safety protection, automatic alarm and limit control. In general, photoelectric switches can be divided into opposing type; diffuse reflection type; specular reflection type; slot type photoelectric switch; optical fiber type photoelectric switch. The main parameters that characterize the static characteristics of the sensor are: linearity, sensitivity, hysteresis, repeatability, drift and so on.

P+F Pepperl+Fuchs through-beam photoelectric switch features: distinguish opaque reflective objects; large effective distance, because the light beam crosses the sensing distance only once; it is not susceptible to interference and can be used reliably and appropriately in the field environment; device consumption High, both units must be installed with cables! It is composed of a transmitter and a receiver, which are separated from each other in structure. When the beam is interrupted, a switch signal change will occur. The typical way is that the photoelectric switches on the same axis can be separated from each other by up to 50 meters. Static characteristics refer to the correlation between the output and input of the sensor for static input signals. Because the input and output are not related to time at this time, the relationship between them, that is, the static characteristics of the sensor can be an algebraic equation without time variables, or the input as the abscissa, and the corresponding output as the It is described by the characteristic curve drawn on the ordinate. The important function of the photoelectric switch The important function of the photoelectric switch is to be able to handle the change of light intensity: use the light beam to reflect the object; make the light beam return instantaneously after a long distance. Special advantages: fast sensing speed, long service life, smart and easy to install and use.
