Class 1 Laser Sensors Can Detect Small Components at Long Distances

Laser sensors are utilized for applications that require the detection of small objects or precise positioning. The laser light source consists of a single wavelength of light, and because the light waves are in phase (coherent), lasers possess a higher energy and power density. This allows a laser to emit a highly concentrated and nearly parallel beam of light, making it capable of detecting very small objects, even at great distances.

An important feature of these lasers is the visibility of the light beam. During the sensor setup process, the laser’s power is temporarily increased. This creates a bright light spot that is clearly visible even in daylight, which greatly assists in the precise alignment of the sensor for optimal performance. To further aid in this, manufacturers like ifm efector offer fine-adjustment mounting brackets that enable exact sensor positioning.

The OG series of laser sensors are listed as FDA Class I laser products. This classification means they are considered safe under all reasonably foreseeable conditions of use and do not require special safety precautions. They also comply with the key international standard IEC 60825 and the European standard EN 60825, which govern the safety and operation of laser products.
