Overview

The DLD-50D is a two-dimensional Time-of-Flight (TOF) LiDAR scanner that measures distance across a 280° plane and outputs point-cloud data over standard Ethernet (100BASE-TX). It is built for engineers developing mobile robots, AGVs/AMRs, and outdoor perception systems that need SLAM-grade localization data, contour/volume scanning, or wide-area object detection.

The series combines ±20 mm repeatability, a 280° field of view, and ambient light immunity above 100,000 lux in a 250 g, 2.5 W package that draws DC 9–36 V and reports data over Ethernet with a dedicated TCP data port. It is a measurement/perception LiDAR — not a certified safety laser scanner, and it is not intended for personnel safety functions under IEC 61496.

DLD-50D and DLD50T8 Are Different Devices

DLD-50D is the Ethernet measurement/navigation family on this page. DLD50T8N and DLD50T8P are separate measuring LiDAR devices with documented NPN/PNP output; they are not alternate names or interchangeable order codes for DLD-50D. Do not apply the DLD-50D manual, SDK, pinout or software assumptions to DLD50T8.

Confirm Software and Supply Scope Before Ordering

  • Provide the full DLD-50DH/DC/DP code, quantity, nearest/farthest targets, reflectivity or target sample, scan coverage and required update rate.
  • State the host operating system, programming language and any ROS/ROS 2 requirement. Request written compatibility confirmation and the matching SDK/programming guide; naming an SDK does not prove those environments are supported.
  • Ask the quotation to identify the software/SDK version, license conditions, cable and connector scope, mounting drawing revision, delivery destination and lead time. Included items and timing follow the quotation.
  • Agree a sample test using known reference distances and the actual target. Check absolute error separately from repeat-reading variation, then verify scan data, host integration and blind-sector orientation.

Features & Benefits

±20 mm repeatability, distinct from ±30 mm detection accuracy

Repeatability describes consistency across repeated readings; detection accuracy describes error relative to the reference distance. Use the ±30 mm accuracy figure for an absolute-distance error budget, rather than treating ±20 mm repeatability as absolute accuracy.

Extra-wide 280° aperture with only an 80° rear blind sector

Wider than a conventional 270° scanner, giving fuller side coverage from a single mounting point — useful when mounting on a vehicle's front corner.

225 kHz ranging engine with model-specific angular resolution and scan rate

DLD-50DH offers selectable 0.08°/0.16°/0.32° angular resolution at 50 Hz for high point-density mapping; DLD-50DP runs 0.32° at 100 Hz for faster refresh in dynamic obstacle avoidance.

Ambient light immunity above 100,000 lux

The manual lists ambient light immunity above 100,000 lux. Confirm the actual target, sun direction and optical-window condition during an outdoor trial; this rating does not quantify performance in every outdoor scene.

Dual-rated range: 50 m at 90% remission and 20 m at 10% remission

The two reflectivity conditions help integrators compare the rated range against their actual targets. The 20 m figure is not an unconditional minimum across all dark surfaces or weather conditions.

IP67-rated housing for harsh environments

Sealed against dust and water ingress, suitable for outdoor and industrial deployment alongside the wide operating temperature range.

A 50 m-class scanner at just 250 g and 2.5 W

Compact 60×60×80 mm housing and low mass make it easy to integrate onto space- and weight-constrained mobile platforms; 2.5 W power draw and DC 9–36 V wide input suit battery-powered robots.

Ethernet output with SimiView and SDK documentation

Data is delivered over Ethernet 100BASE-TX (TCP data port 2368) with UDP broadcast for device search/configuration. The DLD-50D manual describes SimiView for parameter configuration and point-cloud viewing, and DLD-50DSDK APIs for custom integration. Request the applicable installer, SDK package and programming guide; supported operating systems, languages and ROS compatibility are not established by this manual.

Class 1 eye-safe 905 nm laser, −10 to +55 °C operating range

Suitable for continuous operation in occupied spaces, across a wide industrial temperature band.

Applications

Mobile robot / AGV / AMR SLAM navigation and localization (indoor & outdoor) — Evaluate the Ethernet point-cloud output for the intended SLAM stack, using ±20 mm repeatability and ±30 mm detection accuracy as separate figures. The manual describes SimiView and DLD-50DSDK; driver and host-software compatibility must be confirmed before ordering.
Contour scanning and volume/dimension measurement — The DLD-50DH model's selectable 0.08° angular resolution delivers high point-cloud density suited to fine contour capture.
Outdoor perimeter perception and early-warning (non-safety-rated) — >100,000 lux ambient light immunity, IP67 protection, and a 280° field of view suit large-area outdoor monitoring — for perception and early-warning only, not as a safety interlock.
Port / yard wide-area object detection and tracking — The 50 m range at 90% remission and 280° field of view cover large open areas, while the 225 kHz sampling rate supports tracking of moving targets.
High-speed dynamic obstacle detection for fast-moving platforms — The DLD-50DP model's 100 Hz scan rate raises data refresh speed for applications with fast control loops.
Fleet commissioning and installation verification via point-cloud visualization — The manual describes SimiView for point-cloud viewing and parameter configuration. Obtain the matching software version and verify host compatibility before using it to check mounting angle and blind-sector orientation.

DLD-50D User Manual - Shared 50 m LiDAR Reference

English reference edition · 24.3 MB

22 pages. The manual names DLD-50DH/DC/DP variants and is shared here as a reference for the listed 50 m products; it does not establish identical specifications for DLD-50G or DLD50T8N/P. Confirm the ordered interface, wiring and firmware before use. Some dimension-drawing labels remain in Chinese.

Confirm the document and CAD file match the exact ordered version before installation or mechanical design. Contact us if your model is not listed.

How to Select

  1. Choose DLD-50DH if point-cloud density matters most — it offers selectable 0.08°/0.16°/0.32° resolution at 50 Hz.
  2. Choose DLD-50DP if refresh speed matters most — it runs fixed 0.32° resolution at 100 Hz, better suited to fast control loops and dynamic obstacle avoidance.
  3. All three models (DLD-50DH / DLD-50DC / DLD-50DP) share the same Ethernet 100BASE-TX output with TCP data on port 2368 and UDP broadcast for device search/configuration.
  4. This series has no NPN/PNP, relay, or analog output — for hardwired I/O interlocking, select a different DAIDISIKE LiDAR model with NPN/PNP output.
  5. Compare the rated 20 m range at 10% remission with the actual dark target; the 50 m figure applies to 90% remission. Verify the required distance in the intended installation.
  6. If your application scans predominantly dark or low-reflectivity surfaces, plan for the 20 m detection envelope.
  7. All models share the 280° aperture with an 80° blind sector at 320°-0°-40° — orient mounting so the blind sector faces a direction with no required coverage.

When NOT to specify the DLD-50D — and what to use instead

Using DLD-50D as the protective device in a machine safety function

Why not: The DLD-50D specification states plainly that it is a measurement and perception LiDAR only, not a safety laser scanner, and not intended for personnel safety functions per IEC 61496. Its only output is Ethernet 100BASE-TX, with no OSSD.

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 output for a standard PLC input

Why not: The DLD-50D specification explicitly states there is no NPN/PNP, relay or analog output. The only output is Ethernet 100BASE-TX on TCP port 2368.

Use instead: For ordinary process control, compare a DAIDISIKE LiDAR documented with discrete output and confirm electrical compatibility. An Ethernet-to-I/O gateway does not turn this measurement LiDAR into a personnel-protection device.

Detecting dark or matte low-remission targets at long range, designing to the 50 m headline number

Why not: The 50 m range is rated at 90% target remission; the listed 10% remission range is 20 m. The reflectivity of an actual dark surface must be evaluated, not inferred from its colour alone.

Use instead: Design to the 20 m @10% remission figure for dark scenes, or ask us about a longer-range model if 20 m is not enough at the reflectivity you actually have.

You need full 360 degree coverage from one mounted unit

Why not: The documented scan aperture is 280 degrees, with an 80 degree blind sector spanning 320-0-40 degrees. It does not scan the full circle.

Use instead: Orient the mount so the blind sector faces a direction needing no coverage, or use DLD-100DC, which is documented with a full 360 degree scan.

You need both 0.08 degree resolution and a 100 Hz scan rate

Why not: Selectable 0.08/0.16/0.32 degree resolution is documented only for DLD-50DH at 50 Hz. The 100 Hz rate is documented only for DLD-50DP at a fixed 0.32 degree resolution.

Use instead: DLD-50DH for resolution-critical mapping; DLD-50DP for refresh-critical dynamic obstacle avoidance.

Site ambient below -10 or above 55 degrees C

Why not: The documented operating temperature range is -10 to 55 degrees C.

Use instead: Confirm ambient conditions against this range before installation, or contact us if the site falls outside it.

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.

  • DLD-50DC scan-rate and angular-resolution settings, and any configuration-specific combinations beyond the published DLD-50DH and DLD-50DP figures.
  • SDK-supported programming languages and operating systems, and whether a ROS driver is provided.
  • Multi-echo capability and rain / fog / dust penetration performance — not documented for this model.
  • Enclosure material.
  • Certification numbers, issuing bodies and exact-model scope; request the applicable documents before committing a conformity requirement.
  • Repeatability is ±20 mm and detection accuracy is ±30 mm — these are different measures and both are published. If your calculation needs one specifically, confirm which with us.
