Safety laser scanners are used to monitor activity within a dangerous work area. They can be used in stationary or mobile applications. A safety laser scanner is a safety device that provides high-level safety to equipment as well as to people. A safety laser scanner is an optoelectronic device which uses diffused reflection of emitted light and determines the intrusion of person or object in a specified area. There are many different types of safety laser scanners. Examples include a mounted safety scanner, live window safety scanner, and an area laser safety scanner. A mounted safety scanner is mounted either for guarding a horizontal or vertical field in front of equipment or machinery\to protect people from accessing dangerous areas. A live window safety scanner collects security and performance related information from a computer, which is required to find and fix problems. A live window safety scanner then improves the quality of scanner performance and features using the security information collected. An area laser safety scanner is a non-optical scanner that permanently scans a complete workfield at an angle of 190° and several meter radius, to monitor a two dimensional area. Other safety laser scanners are also commonly available.
There are several ways in which safety laser scanners function. A safety laser scanner can provide a 300° scanning angle with safety relay outputs with two programmable zones (warning/ safety). Some examples of safety laser scanners specifications include a maximum angle of 300° and a scanning frequency of 8Hz + 5%. Laser scanning captures a 3-D shape of an object in less time and provides accuracy. Laser scanning uses low power laser scanners which are capable of reading barcodes from 11 inches away. A safety scanner is used for machine safeguarding and also protects workers. A safety scanner can be easily customized and accommodates any surveillance area by accessing and detecting presence of objects in large areas. A mounted safety scanner is available in standard and very-high density versions and can be selected for straight line patterns or omnidirectional patterns. A live window safety scanner includes information that is outlined in the end-user license agreement (EULA) such as run time, type of scan, malicious software detection, and results of malicious software removal. An area laser safety scanner guards stationary machines and mobile system areas with a resolution of 70mm and a scanning angle of 190°. In addition there is low current consumption and comprehension. A scanner manufacturer designs and manufactures safety laser scanners to meet most industry specifications.
Safety laser scanners are used in many applications. Some examples include detecting objects such as walls, columns, and moving objects that include people, as well as for mobile applications and safeguarding machines in industries. Safety laser scanners can also be used in an Automatic Guided Vehicle (AVG). Safety laser scanners should adhere to International Electrotechnical Commission (IEC) standards.
