Safety Laser Scanners


ROTOSCAN RS4/AS-i Safety Laser Scanner
AS-Interface - Safety at work CE TÜV IP 65

Point of operation guarding: Laser scanner Danger zone guarding: Laser scanner Passage guarding: Laser Scanner

Safety Laser Scanners are a cost-effective and flexible protective devices alternative for danger zone guarding of large areas in the vicinity of these machines. Switching between any kind of monitoring areas is possible with up to 6.25 radius, process-conditional according to the application. All configuration data, such as the definition of the zones, the resolution or the response times, is defined with the RS4soft configuration and diagnostics software.

Compactness, protective/warning field combination and field changeover are the essential features of Safety Laser Scanners for guarding corridor supply vehicles. The protection area of the traveling direction and speed of the vehicle is adjusted using staggered protective fields and their situation-conditional activation.

The Safety Laser Scanner also offers very significant advantages for portal processing systems. On one hand the vehicle can be monitored during the movement, while on the other hand, in standstill the Laser Scanner assumes a danger zone guarding of the tools integrated in the portal.
