Safety laser scanner enables safety over networks


SICK has enabled its smallest safety laser scanner, the nanoScan3, with its Safe EFI-Pro standard industrial Ethernet-based safe networking capability. Using the SICK nanoScan3 EFI-Pro, machine builders can more easily design responsive and productive autonomous vehicles and stationary robots through safe integration over industrial networks. 

The ultra-compact SICK nanoScan3 is only eight centimetres tall, so it fits into the tightest spaces, ideal, for example, for small, lightweight automated guide vehicles (AGV) or automated mobile robots (AMR). With SICK’s robust and reliable safeHDDM (High-Definition Distance Measurement) scanning and evaluation technology, the nanoScan3 is capable of multiple dynamically adapting protective fields to protect personnel safety, as well as providing data simultaneously for navigation and contour detection.

The SICK nanoScan3 can also be used for hazardous point, area and access protection in stationary robot applications, as well as for retrofitting into contour or tape-guided mobile vehicles. It is a Type 3 device (IEC 61496-3) and can be used in safety functions up to SIL2 (IEC 62061) and PLd (ISO 13849). 

SICK EFI-pro is an EtherNet-based network for general and safety-related data communications that enables the exchange of data such as control signals, safety-related shut-off signals and diagnostics.  Teamed with the EFI-Pro gateway of SICK’s Flexi Soft safety controller, the system facilitates simple and safe system integration via EtherNet/IP CIP Safety for SICK safety laser scanners such as the nanoScan3, as well as for third-party CIP-Safety devices like robot controllers from leading manufacturers, remote I/O modules and safety PLC’s. 

Dr Martin Kidman, SICK’s Product Manager for Safety Solutions, explained: “By using the SICK nanoScan3 EFI-Pro for simultaneous protective monitoring of multiple fields, there is much less need for switching between monitoring cases, so a robot can be more responsive and efficient. Dynamic protective fields can be shorter, enabling the vehicle to be more efficient without compromising personnel safety. 

“The intelligent and precise sensing capabilities of the nanoScan3 enable robust safety protection in the industrial environment, as well as the outputting of highly accurate measurement data.”
