1. Outline
UHG-08LX is a laser sensor for area scanning. The sensor’s light source is infrared laser of wavelength
785nm. Scan area is 240°semicircle with pitch angle 0.36°. Sensor outputs the distance measured at
every point. The sensor’s maximum measurement is 8000mm with white Kent sheet of 250×250 mm. Laser
beam divergence is 80mm at 8m.
The principle of the 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.
Attention:
The above figure shows the detectable area by the sensor for white Kent sheet. Detection
distance may vary with objects.
2. Important Notice
Do not use as a safety device.
Do not use in military applications or military related research.
UHG-08LX is for indoor use only.
Read this instruction carefully before use.
Non-radiated area: 90º
Power: 12V DC
Interface: USB
Detection Area: 270º
