SICK Launches Powerful and Accurate 2D LiDAR Sensor

The SICK LMS4000 2D LiDAR Sensor’s exceptionally high laser scanning frequency helps to produce more than half a million measurement points per second to calculate the position, shape, volume or surface quality of components over a wide depth of field, and at ranges up to 3 metres.

Both precision and high-speed processing power are assured with the SICK LMS4000.  It achieves a six-fold increase in measurement resolution, compared to previous LiDAR sensors even at very low remissions and no matter where the object is positioned, whether on a conveyor, in a container, carton or pallet, and whether it is free-standing or touching another object.
The SICK LMS4000 is therefore ideal for fast-moving goods handling where accurate dimensions, volumes or positions need to calculated, including automated palletizing and depalletizing, positioning tasks such as robotic pick and place, and shape and contour verification in quality control such as the profiling of car bodies for collision avoidance on a paint line.
The LMS4000 works using visible red laser light and the time-of-flight measurement principle to deliver precise data on the position and size of a wide variety of objects and transmits this data to an external evaluation unit, often in conjunction with an encoder. With SICK’s Continuous Wave technology, the LMS4000 needs no external illumination or additional line lasers. Because it is considerably less sensitive to ambient light, and has a wide depth of field, it can be considered as a cost-effective alternative to vision systems for 3D object profiling in some applications.
Says Neil Sandhu, SICK’s UK National Product Manager for Market Product Manager – Imaging, Measurement, and Ranging:  “The LMS4000 is by far the most accurate 2D LiDAR scanner from SICK with some truly outstanding vital statistics, including a very high 600Hz frequency and an angular resolution of less than 1 degree.  In addition, several devices can be mounted together to extend the measuring range without any danger of interference. The LMS4000 impresses because it achieves extremely high point-density measurements for accurate measurement and 3D profiling of goods at high speeds.  So, our customers have a great opportunity to achieve better throughputs with excellent repeatability and reliability.”
