Product information

The sensors in the R300 series represent a

versatile product line and adopt various func-

tional principles. All sensors operate using

proven Pulse Ranging Technology (PRT) and

are characterized by high sensing ranges and

detection ranges. Contained within the com-

pact housing of the 28 series of light barriers,

the R300 offers all of the properties of PRT

such as maximum reliability when detecting

objects and immunity against ambient light

and cross-talk. To achieve this, the sensors in

the R300 series make use of a number of dif-

ferent kinds of measurement data. What's

more, the sensors are equipped with red light

that is safe for the human eye as standard,

making it easier to align the devices, even

across expansive work areas. These fea-

tures, combined with an innovative and intui-

tive operating concept, provide solutions for

conventional automation tasks delivering the

highest level of performance.
