Maxim Integrated and SICK AG Announce Industry’s Smallest LiDAR Safety Laser Scanner

Maxim Integrated announced that its software-configurable digital IO products helped enable a 50 percent size reduction for the microScan3 Core I/O LiDAR-based safety laser scanner from SICK AG.

The size reduction is designed to allow SICK to expand the new nanoScan3 Safety Laser Scanner for machines and vehicles that require high performance but have minimal mounting space.

Maxim and SICK designers worked side-by-side on the new scanner design by replacing several discrete components with a combination of the MAX14914 software configurable digital IO and the MAX22191 parasitic powered digital input along with other Maxim ICs to achieve the 2x reduction in size compared between the microScan3 Core I/O and the new nanoScan3. The nanoScan3 sits at 106.6mm in length, 117.5mm in width, and 80mm in height

Due to its size reduction, the nanoScan3 features suitable versatility and mounting flexibility on a range of autonomous guided vehicles (AGVs), mobile platforms, and robots, allowing them to navigate safely within space-constrained areas of warehouses and storage facilities.

SICK’s nanoScan3 incorporates the MAX14914 software configurable digital IO, which allowed system designers to reduce the number of components from six discrete components plus peripherals into one IC. The MAX22191 single channel, parasitically powered digital input with accurate input current limiters also helped to achieve the size reduction.  This combination of Maxim’s Digital IO and power solution technology supported SICK to achieve lower power consumption in the nanoScan3 design and provide their end customers the ability to individually configure the IO function of the safety LiDAR sensor.

Further improvements in nanoScan3 came through incorporating the MAX22191 parasitically powered digital input, the MAX22505 USB port protector, the MAX17503 first-rail DC-DC converter and the MAX17545 second-rail DC-DC converter.
