What SICK LiDAR sensors are used in AMR warehouse robots?

SICK LMS series LiDAR scanners (LMS111, LMS151, LMS511) are widely used in AMR warehouse robots for SLAM navigation and safety zone protection. The LMS provides 270° scanning range with up to 50m detection range, generating the point cloud data used for real-time map localization. For safety, SICK microScan3 and S300 safety laser scanners create adjustable warning and protective fields around the AMR, meeting PL-d/SIL 2 safety requirements for human-robot shared spaces.

Q: What SICK sensors are used in AS/RS shuttle systems?

In AS/RS shuttle systems, SICK DT50 and DT100 distance sensors detect pallet position and shuttle travel distance. SICK WL photoelectric sensors detect rack occupancy (whether a pallet or tote is present in a storage location). SICK CLV barcode scanners read pallet IDs at infeed/outfeed conveyors. SICK safety laser scanners provide access protection zones around system entry points. For stack cranes, SICK laser distance sensors (e.g., DT500 series) measure mast position and height with millimeter accuracy.

SICK sensors are the standard in warehouse automation — used in 4-way shuttle systems, stack cranes, AMR robots, and cold storage (-18°C) AS/RS worldwide.

We distribute the full SICK sensor portfolio for warehouse automation applications, with cold-rated options for -18°C to -25°C frozen storage environments.

SICK Sensors FAQ

What SICK sensors are used in AS/RS shuttle systems?+

In AS/RS shuttle systems: SICK DT50/DT100 distance sensors detect pallet position and shuttle travel. SICK WL photoelectric sensors detect rack occupancy. SICK CLV barcode scanners read pallet IDs at infeed/outfeed conveyors. SICK safety laser scanners protect system access points. For stack cranes, SICK DT500 laser sensors measure mast height with millimeter accuracy at speeds up to 180 m/min.

What SICK LiDAR sensors are used in AMR robots?+

SICK LMS series LiDAR scanners (LMS111, LMS151, LMS511) are widely used in AMR warehouse robots for SLAM navigation. LMS511 provides 270° range with 80m detection distance, generating point cloud data for real-time map localization. For safety, SICK microScan3 and S300 safety scanners create adjustable warning and protective fields meeting PL-d/SIL 2 for human-robot shared operation areas.

Can SICK sensors operate in cold storage at -25°C?+

Yes. SICK offers cold-rated versions of their DT50, WL photoelectric, and CLV barcode readers with heated housings for -25°C deep freeze environments. Standard SICK sensors are rated to -10°C or -20°C depending on model. For cold chain AS/RS, always specify the cold-rated or heated-housing variant. Econocontrol supplies cold-rated SICK sensors alongside mechanical systems and drives as an integrated package — ensuring all components are correctly specified for your temperature range.
