Overview
DLD-100D is a single-line (2D) Time-of-Flight (TOF) LiDAR sensor from DAIDISIKE's DLD series. It emits a rotating laser beam and measures distance by time-of-flight, producing a 2D point-cloud scan of its surroundings. Equipment integrators can evaluate it for obstacle perception, positioning reference or ordinary zone monitoring in AGV/AMR, service robot, perimeter, traffic and parking systems. It is a measurement/perception LiDAR, not a certified personnel-protection scanner.
The sensor offers up to 100 m detection range at 90% target reflectivity (40 m at 10% reflectivity), with ranging accuracy of ±20 mm overall and ±10 mm within the 0.1-15 m near range. DLD-100DH scans 280° and DLD-100DC scans 360°; their table lists 50/25 Hz and 0.08°/0.16°/0.32° options. DLD-100DP scans 280° at 100 Hz with 0.32° angular resolution. Do not combine the DP scan rate with a DH/DC resolution option. The series uses a 905 nm Class 1 laser, is IP67-rated, measures 60 x 60 x 80 mm, weighs 250 g excluding cable, and outputs data over Ethernet 100BASE-TX, drawing a maximum of 3 W from a 9-36 V DC supply.
DLD-100D Variant Comparison for Purchasing
| Order code | Scan angle | Scan frequency | Angular resolution |
|---|---|---|---|
| DLD-100DH | 280° | 50 / 25 Hz options | 0.08° / 0.16° / 0.32° options |
| DLD-100DC | 360° | 50 / 25 Hz options | 0.08° / 0.16° / 0.32° options |
| DLD-100DP | 280° | 100 Hz | 0.32° |
DH/DC frequency and resolution options are listed independently in the source table: confirm the intended combination rather than assuming every combination is available. The 100 Hz DP variant is 0.32°. Common parameter rows list 100 m at 90% reflectivity, 40 m at 10%, ±20 mm ranging accuracy, and ±10 mm in the 0.1-15 m near range. These are ranging-accuracy figures, not a published repeatability specification.
Agree the Integration and Acceptance Scope
- Provide the full DH/DC/DP code, quantity, target material/reflectivity, nearest/farthest distance, coverage angle and required scan settings.
- State the controller/host, application-protocol requirement and any OS, programming-language or ROS dependency; request model-specific integration documentation. Ethernet 100BASE-TX alone does not establish those capabilities.
- Ask the quotation to identify cables/connectors, software availability, mounting drawing revision, required certificates, destination and lead time. PTP customization must be agreed for the ordered version.
- Check a sample against known reference distances and the real target, confirm the ordered scan settings and point-cloud integration, and record performance under the expected light/weather conditions. This is an ordinary measurement trial, not validation of a personnel-safety function.
Features & Benefits
Up to 100 m Detection Range
Detects targets up to 100 m away at 90% target reflectivity, so a single sensor can cover a large open area such as a factory aisle, yard entrance or outdoor perimeter without stacking multiple units.
905 nm Class 1 Eye-Safe Laser
The laser source is rated Class 1, meaning it is safe under normal operating conditions for use in environments where personnel are present.
Model-Specific Scan Angle, Frequency and Resolution
DLD-100DH and DLD-100DP scan 280°, while DLD-100DC scans 360°. The DH/DC columns list 50/25 Hz and 0.08°/0.16°/0.32° options without a complete pairing matrix; confirm the chosen combination. DLD-100DP is 100 Hz at 0.32°, not 0.08°.
High-Accuracy Close-Range Measurement
Within the 0.1-15 m near-field range, ranging accuracy is ±10 mm, tighter than the ±20 mm full-range accuracy, useful for precision positioning and short-range obstacle profiling.
Multi-Echo Processing for Dust, Rain and Fog
The source describes multi-echo processing to help distinguish targets from airborne particles or precipitation. It does not provide a quantified rain, fog or dust performance envelope; test the real environment before committing detection performance.
Compact IP67 Housing
Sealed against dust and temporary immersion, the 60 x 60 x 80 mm, 250 g housing is compact and light enough for mounting on mobile platforms such as AGVs and service robots without a major payload penalty.
Wide Power Input, Low Power Draw
Accepts a broad 9-36 V DC input range for easier integration with common industrial and robotic power buses, while drawing at most 3 W.
High Ambient-Light Immunity and Standard Ethernet Output
Remains usable under strong outdoor sunlight, rated above 80,000 lux, and outputs data over a standard Ethernet 100BASE-TX interface for straightforward connection to a host controller or industrial PC.

4 pages, reference revision 2 (2026-10-10). The overview is aligned with the original variant table: DLD-100DP specifies 100 Hz / 0.32 degree; DH/DC options remain model-specific. The original parameter-table and dimension pages are retained. Some dimension-drawing labels remain in Chinese. Confirm the ordered configuration before design.

How to Select
- Choose DLD-100DC for full 360° coverage, such as pole-mounted omnidirectional obstacle avoidance or 360° perimeter monitoring.
- Choose DLD-100DH for a 280° sector scan with a flexible trade-off between resolution and scan frequency, such as wall-mounted or side-mounted installations that do not need full coverage.
- Choose DLD-100DP for the highest 100 Hz scan frequency with a fixed 0.32° resolution, such as high-speed target detection or vehicle pass-through detection where refresh rate matters more than angular resolution.
- For applications needing 0.08° resolution, compare DLD-100DH/DLD-100DC. Their table lists 50/25 Hz and 0.08°/0.16°/0.32° separately, not a complete pairing matrix; confirm the required frequency/resolution combination before ordering. DLD-100DP is 100 Hz at 0.32°.
- Detection range (100 m at 90% reflectivity / 40 m at 10% reflectivity), ranging accuracy (±20 mm, ±10 mm within 0.1-15 m), power supply (9-36 V DC), interface (Ethernet 100BASE-TX), protection rating (IP67), dimensions (60 x 60 x 80 mm) and weight (250 g) are identical across all three variants.

When NOT to specify the DLD-100D — and what to use instead
Using DLD-100D as the protective sensor in a machine safety function
Why not: DLD-100D publishes no Type (IEC 61496), SIL (IEC 61508) or Category/PL (ISO 13849) rating, and its only documented interface is Ethernet 100BASE-TX — there is no OSSD safety output. It is a measurement and perception LiDAR, not electro-sensitive protective equipment.
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.
You need a hardwired NPN/PNP or relay signal into a PLC input or safety relay
Why not: The only data interface documented for DLD-100D is Ethernet 100BASE-TX. No NPN/PNP, relay or analog output is listed in its specifications.
Use instead: An Ethernet-to-I/O gateway to turn the point-cloud or zone data into a switching signal, or a DLD-series model with published discrete I/O such as DLD05A3 or DLD20A5.
Detecting a dark or low-reflectivity target beyond about 40 m, designing to the 100 m headline number
Why not: The 100 m figure is rated at 90% target reflectivity. On a 10% reflectivity target the documented range falls to 40 m — a 60 m difference that depends entirely on what the target is wearing or made of.
Use instead: Design the layout around the 40 m @10% reflectivity figure, and confirm the actual target reflectivity with us before specifying DLD-100D for long-range dark-target detection.
You need the finest 0.08 degree angular resolution and the fastest 100 Hz scan rate in the same unit
Why not: The table lists 0.08 degree as a DH/DC resolution option and separately lists 50/25 Hz frame rates for those variants; it does not establish every supported pairing. DLD-100DP specifies 100 Hz with 0.32 degree resolution. The table does not support a 100 Hz / 0.08 degree ordering claim.
Use instead: DLD-100DH or DLD-100DC when resolution matters most; DLD-100DP when refresh rate matters most.
Site ambient temperature outside -10 to 55 degrees C
Why not: The documented operating temperature range is -10 to 55 degrees C. No wider-temperature operation is published.
Use instead: Verify site ambient against the rating before installation, or ask us about a wide-temperature variant.
Continuous submersion or high-pressure washdown
Why not: DLD-100D is rated IP67, which covers dust ingress and temporary immersion only. Continuous submersion and high-pressure jetting are not covered test conditions.
Use instead: Confirm the exact IP67 test depth and duration with us for washdown environments, or relocate the unit out of the wet zone.
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.
- If you have seen a spec set elsewhere with 0.5-100 m, 1550 nm laser, 180/270 degree scan, dual Gigabit Ethernet + RS485 + CAN, 32-zone discrete output, DC24V/PoE+ or -40 to +70 degrees C, do not treat it as the specification on this page. Ask for the current exact-model datasheet; equivalence or discontinuation is not established here.
- Enclosure material.
- Exact PTP time-synchronisation protocol and precision — the source states only that this is customisable per project.
- Quantified beam-spot size for the small-spot emission system described qualitatively in the source.
- Certification documentation and exact-model scope; request the applicable evidence before committing a conformity requirement.
- Complete scan-frequency/angular-resolution pairing matrix for DLD-100DH and DLD-100DC; the variant table lists options separately.
- Ethernet application protocol, SDK/driver availability, supported OS/languages and ROS compatibility for the ordered DLD-100D version.
- Quantified rain, fog and dust detection performance, and the cable/connector scope supplied with the order.
