The sensor we recommend when a mobile robot has to know where it is: navigation-grade repeatability, a wide 280° window, and a commissioning workflow that takes minutes, not days.
Mapping quality is decided by how consistently a LiDAR reports the same wall at the same distance, revolution after revolution. The DLD-50D was tuned for exactly that: ±20 mm repeatability from a 225 kHz time-of-flight ranging engine, streamed over standard Ethernet so your SLAM software consumes raw point clouds with no fieldbus translation layer in between.
The 280° aperture is wider than a conventional 270° scanner — mounted on a vehicle's front corner, one unit sees the travel path and both flanks, leaving only an 80° wedge (kept against the chassis) unobserved. Range is rated two ways, and we publish both: 50 m on 90% remission surfaces and a guaranteed 20 m on dark 10% remission targets — design dark-scene layouts to the second number.
Start with the data your controller needs, then check the scene it must see. A good sample evaluation should answer these three questions before you commit to a fleet rollout.
Choose this Ethernet-output model when your computer will process profiles for mapping, localization or measurement. If the controller needs discrete NPN/PNP signals, compare the DLD50T8N / DLD50T8P and confirm its output logic separately. These are not interchangeable wiring options.
Test the darkest relevant load, shallow viewing angles and open areas with few stable features, not only a clean wall. Check point-cloud continuity at the actual working distance; a maximum range figure alone cannot validate localization.
Mark the scan plane, blind sector and potential obstructions from the chassis, payload and cables. Check both travel directions and loaded as well as unloaded operation before freezing the mounting position.
Comparing several requirements? Use our industrial LiDAR selection guide to separate range, interface and safety requirements. For longer working distances, review the DLD-100D against the same target conditions rather than assuming a direct replacement.

Not published by the factory (and therefore not claimed here): the full resolution-to-rate pairing matrix, ROS driver status and SDK language list, multi-echo behaviour, and enclosure material. Ask us to confirm any of these in writing. Certification documents are available on request. Same hardware with added NPN/PNP discrete I/O ships as DLD50T8N / DLD50T8P.
The scanner supplies measurements; mapping, localization and application decisions remain in your host software. Use this practical acceptance sequence with the English manual below.
Keep personnel-protection functions independent of this evaluation. Our guide to safety scanners versus navigation LiDAR explains why a good navigation scan is not evidence of a certified protective function.
Ethernet point clouds feed SLAM and reflector-navigation stacks; 148 g and 2.5 W barely dent the battery budget.
0.08° resolution on the DH model densifies profiles for dimensioning, pile measurement and shape checks.
Sunlight-proof to >100,000 lux and sealed to IP67 for gates, yards and dock aprons — perception and early warning only.
The 100 Hz DP variant refreshes quickly enough for higher-speed vehicles and short control loops.

A SLAM or reflector-navigation stack compares scan after scan; what corrupts the pose estimate is jitter between those scans, not a constant offset. The DLD-50D holds ±20 mm repeatability — the tightest in our LiDAR range — which shows up directly as steadier localization and cleaner accumulated maps. It is the one ranging figure the factory publishes for this model; if your calculation needs an absolute-accuracy number as well, ask us and we will confirm it in writing.
The aperture is 280°, with the blind sector spanning 320°–0°–40° in device coordinates. Mount so that dead zone faces something you never need to see — the vehicle body on an AGV corner, the wall behind a fixed installation. On a front-corner mount, the 280° window covers the travel direction and both flanks from a single unit.
Power the unit (9–36 V DC), connect Ethernet, and the free SimiView tool discovers it over UDP broadcast and renders the live point cloud — the fastest way to verify mounting angle and blind-sector orientation across a fleet. Production data flows over TCP on port 2368; the default device IP is 10.10.10.121. The DLD-50DSDK is available for custom integration.
DH gives selectable 0.08°/0.16°/0.32° angular resolution at 50 Hz: choose it when point density decides the outcome, as in contour capture, volume measurement or detailed mapping. DP runs a fixed 0.32° at 100 Hz: choose it when your control loop is fast and refresh rate beats density, as in dynamic obstacle detection on quick platforms.
Ambient-light immunity is rated above 100,000 lux — the level of direct midday sun — so loading docks, gateways and skylit halls are within its design envelope, and the IP67 housing handles dust and temporary immersion. Multi-echo weather penetration is not documented for this model; if fog or heavy dust is central to your site, tell us and we will point you at the right unit.
No — its only output is Ethernet; there is no NPN/PNP, relay or analog channel, and no OSSD. This is a perception/measurement LiDAR, not an IEC 61496 certified safety component; do not use it as the sole means of personnel protection. Need hardwired switching from the same platform? See the DLD50T8N/P. Need a genuine safety function? Specify the ST27 Type 3 safety scanner.
MOQ is 1 unit — most integrators start with a single evaluation sensor on the bench with SimiView. Lead time is typically 3–15 days depending on model and quantity, stated in writing on the quotation. Factory-direct export from China; OEM/ODM programs for fleet builders (labelling, cabling, parameter presets) are welcome via the inquiry form.
