Foshan, China, September 1, 2026 — Foshan DAIDISIKE Optoelectronics Technology Co., Ltd. has published an updated industrial LiDAR scanner selection resource for automation engineers, mobile-robot developers, system integrators and industrial security professionals.

The resource organizes the company’s LiDAR portfolio according to the job each scanner is designed to perform. Applications include personnel protection, AGV and AMR obstacle avoidance, configurable zone detection, SLAM navigation, industrial measurement and long-range perimeter monitoring.

One of the most important points addressed by the new resource is the distinction between a certified safety laser scanner and a standard perception or navigation LiDAR.

A scanner that creates a detection zone and switches an output may appear similar to a safety-rated device. However, a conventional NPN, PNP or Ethernet output does not provide the redundant diagnostics and fail-safe behavior required for a personnel-protection safety function.

Within the current DAIDISIKE range, the ST27 is the model intended for certified personnel-protection applications. It is specified as a Type 3 electro-sensitive protective device with SIL 2 and PL d ratings, dual OSSD safety outputs, a protective-field range of up to 5 meters, a 276-degree scanning angle and a 100-millisecond response time.

Other models in the DLD, SDLD, DLDS and JPTG families are intended for perception, navigation, equipment protection, obstacle avoidance, area monitoring and perimeter detection. These models should not be used as the sole safety device responsible for stopping hazardous machinery to protect personnel unless the specific model carries the required safety certification.

For AGV and AMR projects, the DLD05A3-3N and DLD20A5-5N models provide 5-meter and 20-meter scanning options for obstacle detection and configurable monitoring zones. The SDLD-05A and DLDS2030A-5S address mid-range detection requirements for larger mobile platforms, machine cells and wider industrial aisles.

For outdoor and long-range monitoring, the DLD30T-5N provides detection at distances of up to 40 meters and is intended for industrial perimeter security and intrusion monitoring. The DLD-100D extends the available range to 100 meters for yards, access lanes and larger industrial sites.

Navigation and mapping applications have different priorities. Models such as the DLD-50D provide point-cloud information for SLAM, localization and route planning. Measuring models can combine Ethernet data with switching outputs, allowing an industrial controller to receive both detailed scan information and configurable zone-status signals.

Depending on the model, available communication and integration options include RS485, Modbus, digital NPN or PNP outputs and Ethernet. This allows LiDAR data to be connected to PLCs, industrial computers, mobile-robot controllers and monitoring systems.

The updated guide encourages engineers to define the required function before comparing detection range. A longer maximum range does not automatically make a scanner more suitable. Selection should also consider scanning angle, response time, angular resolution, target reflectivity, vehicle speed, braking performance, mounting position and environmental conditions.

For a moving AGV or AMR, the required detection field must account for the distance traveled during scanner response, controller processing, brake engagement and mechanical deceleration. The calculation should use the vehicle’s maximum permitted speed, heaviest payload and worst expected floor condition.

Increasing vehicle speed has a major effect on stopping distance because the deceleration distance rises with the square of speed. If the required protective field does not fit within the available aisle, improving braking performance or reducing speed may be more effective than selecting a longer-range scanner.

Environmental suitability is another important selection factor. Dust, oil mist, rain, fog, vibration, direct sunlight, reflective metal and dark materials may affect detection availability. Integrators should test the actual target materials and operating environment rather than relying only on ideal laboratory specifications.

Scanner placement must also account for blind spots. A two-dimensional LiDAR observes a single scanning plane. Vehicle bodywork, forks, overhanging loads, machine frames and structural columns can block that plane. Large mobile platforms and machine cells may therefore require two scanners with overlapping fields.

For mobile-robot systems that require both personnel protection and navigation, DAIDISIKE recommends separating the two responsibilities. A certified safety scanner should manage the safety-related stop function, while a navigation LiDAR supplies point-cloud data for localization, mapping and path planning. The safety layer should retain priority over the navigation layer.
