A long-range 2D perception LiDAR for integrators who need one compact sensor to watch a whole aisle, gate, lane or fence line — indoors or out.
The DLD-100D spins a 905 nm Class 1 laser through its surroundings and times each return flight, producing a 2D distance profile of everything in the plane on every revolution. What sets it apart in our line-up is reach: rated up to 100 m at 90% reflectivity and 40 m at 10% reflectivity, from a housing that measures just 60 × 60 × 80 mm and weighs 250 g.
Published ranging accuracy is ±20 mm and ±10 mm inside the 0.1–15 m near field, which is where docking, positioning and profiling work actually happens. The document lists multi-echo processing, ambient-light immunity above 80,000 lux and an IP67 enclosure. Validate the actual target, mounting and weather conditions: neither the enclosure rating nor multi-echo processing guarantees outdoor detection in all circumstances.
Original DAIDISIKE schematic. Start with DC for full-circle coverage, DH for a sector scan, or DP for the listed 100 Hz option. Confirm the suffix and supported rate/resolution pairing; family-wide maximum figures are not simultaneous.

The model table in the supplied PDF is the basis for the variant figures above: DH/DC list 50/25 Hz and 0.08°/0.16°/0.32° options; DP lists 100 Hz at 0.32°. Confirm the requested configuration. Values we cannot document — enclosure material, quantified beam spot, exact PTP sync precision — are left out rather than invented; PTP is customizable per project, so ask us with your requirement. Certification documents are available on request.
A long-range LiDAR is most useful when its scan plane, target return and data interface match the job. Use the following questions to narrow the configuration before ordering an evaluation unit.
Record target dimensions, colour, surface angle and the closest and farthest measurement distances. Use the 90% and 10% reflectivity ratings as stated test conditions, then trial your real objects. A small dark target is not equivalent to a large bright test surface.
A 2D scanner measures one plane, not a complete 3D volume. Show the proposed mounting height, obstructions and areas hidden behind structural members. For a closed sweep, evaluate DC; for a sector or higher listed scan rate, compare DH and DP against the variant table above.
Identify the IPC or controller, operating system and data format your software needs. Request the matching protocol and connection instructions; Ethernet 100BASE-TX alone is not a promise of a particular PLC protocol or software driver. Confirm any PTP requirement separately.
Include direct sunlight, wet or dusty optics, representative targets and the intended environmental limits in the trial. Define a response to invalid or missing data. Our outdoor LiDAR guide explains why weather performance and enclosure sealing are separate checks.
Compare the DLD-50D navigation LiDAR when your range requirement fits the 50 m family. If the controller also needs ordinary NPN/PNP signalling, review the DLD50T8N/P output options and confirm their electrical details. For the overall selection process, see our industrial LiDAR selection guide. Neither ordinary Ethernet nor NPN/PNP output establishes a personnel-protection safety function.
For a model recommendation, send the target and distance, installation sketch, required scan coverage, host controller, environment and quantity through our application enquiry page.

One IP67 unit sweeps a fence line or gate zone to 100 m on bright targets — fewer poles, fewer cables than beam chains.
The 100 Hz DP variant profiles vehicles passing lanes, gates and kerbside points for presence, class and dimension logic.
250 g and 3 W fit battery platforms; the point cloud feeds obstacle avoidance and localization stacks over Ethernet.
Long-range scan data can support large-vehicle awareness around cranes and loading areas. Validate target returns in dust, drizzle and the site's actual lighting; multi-echo does not remove weather limits.
Plan around two numbers, not one. On a bright 90%-reflectivity surface the rated range is 100 m; on a dark 10%-reflectivity surface — black rubber, dark clothing, matte housings — it is 40 m. If your critical target could be dark, lay out the installation against the 40 m figure and treat anything beyond it as a bonus, not a guarantee.
DC is the only one that closes the full circle (360°), so choose it for pole-mounted omnidirectional monitoring. DH scans a 280° sector with selectable 0.08°/0.16°/0.32° resolution at 50/25 Hz — the mapping and fine-target choice. DP trades resolution for speed: fixed 0.32° at a 100 Hz refresh, suited to counting or tracking fast-moving vehicles. Range, accuracy, housing and interface are identical across all three.
The DLD-100D document lists multi-echo processing, >80,000 lux ambient-light immunity and an IP67 enclosure. These features do not guarantee detection in every outdoor condition. Rain, fog, airborne dust or a contaminated optical window can affect the returned signal and usable range. Test representative weather and targets at your installation, and define what the application should do when valid measurement data are unavailable.
The documented interface is Ethernet 100BASE-TX — your controller or IPC ingests the scan data over the network. There is no NPN/PNP, relay or analog output on this model, so a hardwired trip signal needs either an Ethernet-to-I/O gateway or a sibling model with discrete outputs, such as the DLD50T8N/P.
No. This is a perception/measurement LiDAR, not an IEC 61496 certified safety component; do not use it as the sole means of personnel protection. It has no OSSD outputs and no Type/SIL/PL rating. Where a scanner must stop a machine to protect a person, specify our ST27 Type 3 safety laser scanner and size the field per ISO 13855.
9–36 V DC input (about 0.25 A at 12 V, 3 W max), 60 × 60 × 80 mm envelope, 250 g without cable, IP67 sealing, −10 °C to +55 °C operating range, under 20 s start-up. The document lists a 905 nm Class 1 laser and a rated working life of 5 years based on the scanning motor. Follow the supplied installation and laser-safety instructions for the delivered unit.
Do not assume that combination. The model table lists 50/25 Hz and 0.08°/0.16°/0.32° options for DLD-100DH/DC, and 100 Hz with 0.32° for DLD-100DP. Select the suffix and confirm its available rate/resolution pairing before purchase; the family-wide headline values are not all available simultaneously.
