General URG-04LX is a laser sensor for area scanning. The light source of the sensor is infrared laser of wavelength 785nm with laser class 1 safety. Scan area is 240º semicircle with maximum radius 4000mm. Pitch angle is 0.36º and sensor outputs the distance measured at every point (683 steps). Laser beam diameter is less than 20mm at 2000mm with maximum divergence 40mm at 4000mm. The principle of distance measurement is based on calculation of the phase difference, due to which it is possible to obtain stable measurement with minimum influence from object’s color and surface gloss. URG-04LX is designed under JISC8201-5-2 and IEC60947-5-2 standards for industrial applications. Non-radiated area: 120º Power: 5v DC Interface: RS-232C, USB Detection Area: 240º Max. Distance: 4000mm Figure 1 Note Figure 1 shows the detectable area for white Kent sheet (70mm×70mm). Detection distance may vary with size and object. 2. Important Notice This sensor is designed for indoor use only. This sensor is not a safety device/tool This sensor is not for use in military applications Read specifications carefully before use.URG-04LX Specification C-42-3319A 2/5 Title Drawing No3.
