Pepperl+Fuchs photoelectric sensor Pragmatic service, reputation carries the future

The P+F Pepperl+Fuchs photoelectric sensor through-beam photoelectric switch is composed of a transmitter and a receiver. The two are separated from each other in structure. When the beam is interrupted, a switch signal change will occur. The typical way is located in the same The photoelectric switches on the axis can be separated from each other up to 50 meters. Photoelectric switch type proximity switches are 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.

P+F Pepperl+Fuchs photoelectric sensor photoelectric sensor 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! The static characteristic of the photoelectric switch refers to the correlation between the output and the input of the sensor for the static input signal. 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 main parameters that characterize the static characteristics of the sensor are: linearity, sensitivity, hysteresis, repeatability, drift and so on. The important function of the photoelectric switch The important function of the photoelectric switch is to be able to deal with 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.
