SICK scangrid2 400x275SICK has announced the scanGrid2, a safe multibeam scanner that uses solid-state lidar technology designed for small autonomous and line-guided transport vehicles. Certified as a Type 2/SIL 1 safety sensor (IEC 61496-3), the scanGrid2 can protect hazardous areas up to performance level C, and works well for collision avoidance. An app and cloning function also ensure a high level of uptime and fast fleet deployment, SICK said.

“With this sensor, manufacturers of autonomous and line-guided autonomous vehicles gain a cost-effective safety solution that can boost the productivity of applications,” said Aaron Woytcke, market product manager of industrial safety at SICK USA. “Specifically, this means increasing the speed or payload of the vehicles, or being able to eliminate mechanical barriers like fences.” 

Conventional safety laser scanners are often not suitable for simple and cost-effective small vehicles for economic reasons, the company added. Users end up choosing between limiting the speed or payload of the vehicle or avoid operating them in unfenced areas to minimize the risks associated with the vehicles. SICK said scanGrid2 now offers users new possibilities for successfully increasing the productivity of small autonomous and line-guided carts. Switching to a safety sensor is now a viable option, with initial installations showing productivity increases between 50 and 70%, the company added.

Instead, the device uses only semiconductor elements in conjunction with geometrically arranged optics modules to span a protective field of 150 degrees. Within the defined protective field zone, scanGrid2 can solve Type 2 classified, performance level C safety requirements in the context of safety applications, SICK said.

The company also redesigned configuration and diagnostic features. In addition to tools such as the Safety Designer software, SICK engineers implemented an additional Near Field Communication (NFC) interface. The combination enables diagnostics to be performed on the sensor quickly and easily, including through a smartphone. The advantages of this approach are also readily apparent during commissioning or serving, SICK said. Sensor configurations can transfer wirelessly from one sensor to another through a cloning function in the app.

“When it comes to the use of safety sensors, easy configuration, fast commissioning, and diagnostics are the key aspects our customers are looking for,” said Woytcke. “Ensuring fast servicing also saves valuable time and money.”
