DLDS2030A-5S Laser Scanning Radar
DLDS2030A-5S is the same 20 m 2D TOF obstacle-avoidance LiDAR as our DLD20A5 series, sold under an earlier model code. If you bought under this code, this is your unit — the specifications below are the DLD20A5 figures.

Overview
DLDS2030A-5S and DLD20A5-5N / DLD20A5-5P are the same physical device. The DLDS2030A-5S code was used for earlier shipments; DLD20A5 is the current designation. We keep this page so customers who bought under the older code can find the right data sheet and order the matching replacement.
It is a 2D time-of-flight obstacle-avoidance LiDAR covering 0.05-20 m across a 270 degree field, with three discrete switching outputs plus a status output, 16 zone sets, and IP65 protection. It carries no safety rating and must not be used to protect a person — see the section below.
For the full specification, model codes and ordering information, see the DLD20A5 page at /products/lidar/dld20a5-5n-dld20a5-5p-2d-tof-obstacle-avoidance-lidar/.
Features & Benefits
Dedicated Factory Accessory Line
A dedicated factory accessory line is available for this scanner, DLDS-1 through DLDS-6. Customers can source matching accessories directly from the factory rather than sourcing third-party parts on their own.
Featured Position in the Catalogue Lineup
DLDS2030A-5S holds a dedicated page in the factory catalogue, positioned alongside the DLD-05D and DLD-20D as a featured scanning radar model, indicating it is an actively promoted model in the line rather than a legacy or discontinued one.

When NOT to specify the DLDS2030A-5S — and what to use instead
Using the DLD20A5 to protect a person in a machine-safety stop circuit
Why not: No Type (IEC 61496), SIL (IEC 61508) or Category/PL (ISO 13849) rating is documented for this sensor, and its outputs are 3 NPN/PNP discrete switches (DC 30 V, 50 mA max) plus a status signal — not OSSDs.
Use instead: The DAIDISIKE ST27 Series Safety Laser Scanner — Type 3 / SIL 2 / Cat. 3 PL d, OSSD outputs, 3 m or 5 m protective field at 1.8% remission.
Setting braking or stopping-distance logic against the full 20 m range for dark or low-reflectivity targets
Why not: The published 0.05-20 m figure carries no target-reflectivity qualifier. Other LiDARs in this line state their range against a specific remission (for example DLD05A3's siblings quote 90% and 10% cases separately), but the reflectivity basis for the DLD20A5's 20 m number is an open item we have flagged internally and have not resolved with the factory. Real range on a dark target could be materially shorter than 20 m.
Use instead: Ask us for the reflectivity basis of the 20 m figure before you finalise zone sizes. Until it is confirmed, build in margin and add a closer redundant zone for dark or unknown-reflectivity targets.
The application only ever needs to see objects within about 5 m
Why not: The DLD20A5 is built and tuned for 0.05-20 m coverage, and its zone-set library is sized around far-field staged braking rather than tight short-range logic. You would be paying for range you do not use.
Use instead: The mechanically identical DLD05A3-3N / DLD05A3-3P (0.05-5 m) from the same housing platform.
You need Ethernet or fieldbus ranging data rather than a hardwired trigger
Why not: The DLD20A5 is pure discrete I/O — 3 NPN or PNP switching outputs plus 1 status signal — with no Ethernet or bus protocol of any kind.
Use instead: DLD30T-5N or the DLD50T8 series, which output Ethernet-based ranging data instead of switch signals.
Wiring the -5N or -5P variant without first checking the panel's input convention
Why not: The -5N variant is NPN (sinking) only and the -5P variant is PNP (sourcing) only. There is no combined or field-switchable output type.
Use instead: Verify the input polarity before ordering: -5N for sinking-input cards, -5P for sourcing-input cards.
Flagging a slender object — a thin post, cable or pedestrian leg — near the far edge of 20 m using the 0.3 degree setting
Why not: At 0.1 degree resolution scan points sit roughly 35 mm apart even at 20 m. The coarser 0.3 degree setting spreads them further at the same distance, raising the chance a slim object is missed between adjacent points.
Use instead: Use the 0.1 degree setting for long-range slim-object detection, or add a dedicated closer-range sensor as backup at that point.
Specifications we do not publish yet
We only publish a figure once we are confident it is true. The items below are still being validated through further testing and real-world customer feedback, so for now we would rather leave them open than guess. If one of them matters to your design, ask us for the latest validated status.
- DLDS2030A-5S is the same device as DLD20A5. Any specification not listed here is not published for the DLD20A5 either — see that page's own list.
- Target reflectivity basis for the published 0.05-20 m maximum range — this directly affects stopping-distance planning, so ask us before you fix a safety margin
- Exact function of each accessory item DLDS-1 to DLDS-6.
