Laser measurement without compromise - precise, fast and reliable
The LMS4000 2D LiDAR sensor is particularly well-suited for use in intralogistics, material handling and in all areas in which goods must be quickly and systematically analyzed and moved. With the LMS4000, SICK is offering the ideal solution for measuring objects regarding their position, shape, volume or surface quality and evaluating and processing them correspondingly. Regardless of the object position in containers, cartons or on pallets, or whether they are free-standing or touching one another, the sensor measures precisely with high sampling density and a wide dynamic range. A high throughput with comprehensive process reliability and low maintenance needs is the result.

The all-rounder for a wide range of applications
The LMS4000 2D LiDAR sensor, when used as a standalone component in automated production, delivers precise data about the position and size of a wide variety of objects. The sensor passes this data on to an external control unit, often combined with an encoder. This results in many fields of application, such as volume and position detection of objects, pick and place or palletizing and depalletizing tasks, empty container detection, quality inspection of solar cells, engine blocks and aircraft parts, trains or tunnel walls and much more.
High precision, speed and point density make the LMS4000 a real all-rounder for volume measurement, quality control systems and palletizing tasks. Large or small, light or dark objects pose no problems for the LiDAR sensor.
Object measurement - quick and precise
The LMS4000 measures objects quickly and precisely, independent of their shape, color or surface quality. The aperture angle of 70° results in a wide scanning area, which a continuous laser scans at 600 Hz using a rotating hexagonal mirror. Every scan generates 841 individual measuring points. The use of a red light laser within the visible spectrum makes precise alignment easier.
Large working range
Objects with a height of 1 m can be measured consistently by the LMS4000 across a width of 2.6 m. For objects 2 m high, the measuring field width can be up to 1.4 m. In addition, the device variant with increased scanning range even enables the measurement of objects with a cross-section of 3 m x 3 m or even 4 m x 2 m.
Targeted control and reduction of data transmission
The laser scanner can be switched on and off via photoelectric sensors or software commands. This ensures data is only produced when objects are actually being measured. Internal filters allow for targeted reduction of data to the specific application and thus also relieve the overall system.
Precise and reliable measurement procedure
The continuous-wave method is based on the principle of phase correlation. The object reflects the continuously emitted laser beam onto the receiver of the laser scanner. The resultant phase delay between the emitted and received beam can be used to precisely determine the distance. At the same time, the measurement procedure is resistant to external influences, e.g. ambient light or temperature fluctuations.
Four data channels
In addition to distance data, the sensor can also transmit reflectance, angle correction and quality values as required. This makes it possible to visualize even slight differences in object color and texture, compensate for accelerations acting on the sensor, and identify critical measurement points. The output data format can be extended or reduced individually by each channel.
Extending the measuring range
Using multiple laser scanners prevents shadowing effects and allows larger measurement fields to be used. The system can synchronize the motors of the rotating mirrors to ensure the devices do not mutually interfere with one another.
Precise and reliable measurement procedure with large depth of field and measuring field width. Four data channels can be combined as required and data transmission with the laser control can be activated as needed.
Digital filters for increased performance
Digital filters for pre-processing and optimizing the measured values further increase the performance of the LMS4000. This enables the laser scanner to be directly tailored to the relevant application. Faults are reliably prevented, and data quantities optimized for downstream processes.
Targeted preprocessing of data thanks to a wide range of filter options reduces effort in downstream process steps.
