Overview

The DLD30T-5N is a Time-of-Flight (TOF) single-line/single-layer 2D LiDAR that performs a 270° rotational scan and outputs measurement (point-cloud) data — distance and angle for each scan point — over a standard Ethernet interface, rather than pre-processed switch outputs. It is built for system integrators and OEMs who develop their own navigation, SLAM, or area-monitoring software and need direct access to raw scan data, including mobile robot / AGV manufacturers, warehouse automation integrators, and machine builders mounting sensors on moving equipment such as robot arms, gantries, and forklifts.

The sensor delivers an adjustable angular resolution down to 0.08°, a scan frequency adjustable from 10 to 30 Hz, and a dual-rated detection range of 30 m on 90% reflectivity targets and 10 m on 10% reflectivity (dark) targets. Housed in a palm-sized 50 × 50 × 76 mm, 148 g IP67 enclosure with a Class 1 eye-safe 905 nm laser, it outputs point-cloud data over a 100BASE-TX Ethernet interface and runs on DC12-24V power.

Features & Benefits

Adjustable angular resolution down to 0.08°

Delivers dense, gap-free contour point data on distant or slender objects such as posts, shelf legs, or human legs — fine enough for reliable mapping and navigation. Resolution is adjustable so users can trade point density against data volume.

Honest dual-rated detection range

30 m on 90% remission (reflectivity) targets, 10 m on dark 10% remission targets, published together so integrators can select the sensor based on the worst-case surface — dark clothing, black bins — rather than a single best-case number.

Scan frequency adjustable from 10 to 30 Hz

Lower frequency gives denser point capture for static mapping and measurement tasks; higher frequency gives faster refresh for dynamic monitoring — both on the same unit.

Palm-sized, lightweight housing

At 50 × 50 × 76 mm and 148 g, the housing is compact enough to mount on space- and weight-constrained platforms such as small mobile robots, moving gantries, or robotic-arm end-effectors.

IP67 housing with Class 1 eye-safe 905 nm laser

Rated for dusty and washdown-prone industrial environments, and safe for continuous operation in areas where personnel are present, per laser safety classification.

Standard 100BASE-TX Ethernet measurement data output

Connects directly to industrial PCs or navigation controllers over a single Ethernet cable — the common interface used by navigation and mapping software stacks.

Applications

Mobile robot / AGV navigation and SLAM mapping — The 30 m range plus Ethernet raw point-cloud output covers large warehouse aisles and feeds directly into standard SLAM software stacks.

Warehouse and logistics equipment contour detection and positioning — Dense point data at fine angular resolution can resolve container and pallet edges for positioning tasks such as gantry-to-container alignment or stacking.

Fixed-mount area monitoring and wide-range object presence detection — The 270° scan and adjustable 10-30 Hz frequency let a single unit cover a wide static or slow-changing area.

Outdoor / semi-outdoor perimeter scanning — The IP67 housing supports installation locations exposed to dust or washdown.

Robot-arm end-effector or gantry-mounted distance sensing — The compact 50 × 50 × 76 mm, 148 g housing is light enough to mount on a moving arm or gantry without adding significant payload.

How to Select

If your application needs raw distance/angle point-cloud data for custom navigation or mapping software, choose DLD30T-5N with its Ethernet measurement data output.
If your application only needs a simple switch signal for obstacle avoidance, choose a switch-output series instead — DLD30T-5N is a point-cloud measurement sensor, not an on/off switch sensor.
Always size the sensor to the worst-case (lowest) reflectivity figure for your target material: 30 m at 90% reflectivity, 10 m at 10% reflectivity.
Choose a finer angular resolution setting (toward 0.08°) for denser point clouds when scan time and data volume allow; choose a coarser setting to reduce data volume and processing load.
Choose the lower end of the 10-30 Hz scan frequency range for static measurement/mapping tasks that benefit from denser points per scan, and the higher end for dynamic monitoring tasks that need faster refresh.
Confirm your platform can supply a stable DC12-24V power source before installation.
Confirm available mounting space and payload budget: at 50 × 50 × 76 mm and 148 g, DLD30T-5N suits space- and weight-constrained mounting positions such as small robots or arm ends.

When NOT to specify the DLD30T-5N — and what to use instead

Using the DLD30T-5N as the protective device in a machine safety function

Why not: Its only confirmed output is raw point-cloud measurement data over 100BASE-TX Ethernet. There is no discrete safety switching output, and no Type (IEC 61496), SIL (IEC 61508) or Category/PL (ISO 13849) rating is published for this model.

Use instead: The DAIDISIKE ST27 Series Safety Laser Scanner — Type 3 / SIL 2 / Cat. 3 PL d, dedicated OSSD outputs, 3 m or 5 m protective field at 1.8% remission.

Detecting dark, low-reflectivity objects — black bins, dark workwear, matte rubber — out near the headline 30 m figure

Why not: The range is dual-rated: 30 m applies at 90% reflectivity only. At 10% reflectivity the confirmed range is 10 m. That is a third of the headline number.

Use instead: Design the working distance around the 10 m @10% figure for dark targets, and confirm performance on your actual target material with us before committing to a layout.

Expecting the scanner to resolve thin objects — posts, cart legs — right at the far end of its 30 m range

Why not: Even at the finest confirmed 0.08 degree angular resolution, the spacing between measured points widens with distance: roughly 14 mm at 10 m but roughly 42 mm at 30 m. A thin target at 30 m can fall between points.

Use instead: Validate detection of your actual object size at the actual working distance with a test scan, or ask us about denser point spacing for that range.

Deploying outdoors in extreme heat or cold on an assumed temperature rating

Why not: No operating temperature range is confirmed for DLD30T-5N in our current factory material. A wider range appearing in third-party material conflicts with the factory datasheet and we do not publish it.

Use instead: Confirm the actual operating temperature range with us before specifying this sensor for a hot or cold installation.

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.

Operating temperature range.
Number and logic of switchable / programmable detection zones.
Response time / measurement output latency.
Power consumption and current draw; whether PoE is supported.
Application-layer Ethernet protocol beyond the confirmed 100BASE-TX physical layer, and connector pinout.
Housing material.
MTBF or expected service life.
Certification documentation. Certification documents are available on request.
Number of NPN discrete output channels, their switching rating and zone-trigger logic. The output is confirmed present but these details are not yet published.
Whether a PNP (sourcing) variant of the DLD30T is available.

Frequently Asked Questions

What does "TOF" mean in the DLD30T-5N LiDAR, and how does it differ from triangulation-based sensors?

TOF (Time-of-Flight) measures distance by timing how long a laser pulse takes to travel to a target and return, which allows the DLD30T-5N to measure across its full rated range (up to 30 m at 90% reflectivity) from a single sensor position, unlike short-range triangulation-based distance sensors.

What is the actual detection range of the DLD30T-5N?

The DLD30T-5N is rated for 30 m on targets with 90% reflectivity (remission), and 10 m on darker targets with 10% reflectivity. Actual usable range on a given object depends on that object's surface reflectivity.

What data does the DLD30T-5N output, and over what interface?

The DLD30T-5N outputs measurement (point-cloud) data — distance and angle values for each scan point across its 270° field of view — over a 100BASE-TX Ethernet interface.

What angular resolution does the DLD30T-5N support?

The angular resolution is adjustable down to a minimum of 0.08°. Finer resolution gives denser point data (smaller angular spacing between measured points) at the cost of higher data volume.

What scan frequency does the DLD30T-5N run at?

The scan frequency is adjustable from 10 Hz to 30 Hz. Lower frequencies give denser point clouds per rotation; higher frequencies give faster refresh for dynamic scenes.

Is the DLD30T-5N laser safe for use around personnel?

The DLD30T-5N uses a 905 nm laser rated Class 1 (eye-safe) per laser safety classification, and it is IP67-rated for dusty or washdown-exposed environments.

What is the measurement accuracy of the DLD30T-5N?

Detection accuracy is ±30 mm, as specified in the product datasheet.

What is the physical size and weight of the DLD30T-5N?

The housing measures 50 × 50 × 76 mm and weighs 148 g.

What power supply does the DLD30T-5N require?

The DLD30T-5N operates on DC12-24V.

Can the DLD30T-5N provide certification documents such as CE, FCC, or RoHS?

Certification documents are available on request.
