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.
Features & Benefits
±20 mm repeatability — the tightest in our LiDAR line-up
Tighter repeat accuracy translates directly into lower jitter for SLAM localization and reflector-based navigation, and cleaner, more consistent maps.
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
Rated to keep measuring under direct midday sunlight — a light level typical of outdoor loading docks, gateways and skylit halls, a condition that disables many indoor-oriented LiDAR sensors.
Dual-rated range: 50 m at 90% remission, a guaranteed 20 m on dark 10% remission targets
The two-tier range rating lets integrators design around a realistic 20 m minimum for dark/low-reflectivity targets rather than the headline 50 m figure alone.
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.
Standard Ethernet output with auto-discovery, free visualization software, and an SDK
Data is delivered over Ethernet 100BASE-TX (TCP data port 2368) with UDP broadcast for device search/configuration; the bundled SimiView software gives instant point-cloud visualization for commissioning, while the DLD-50DSDK supports deeper custom integration.
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.

Same device, other model codes
How to Select
- Choose DLD-50DH if point-cloud density matters most — it offers selectable 0.08°/0.16°/0.32° resolution at 50 Hz.
- 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.
- 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.
- 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.
- Design around the 20 m guaranteed range on 10% remission (dark) targets rather than the 50 m figure, which applies to 90% remission targets.
- If your application scans predominantly dark or low-reflectivity surfaces, plan for the 20 m detection envelope.
- 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 to interlock with a safety relay or a basic PLC digital 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: A DAIDISIKE LiDAR documented with discrete output, or an Ethernet-to-I/O gateway between the scanner and the controller.
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 guaranteed range on a 10% remission target — black rubber, matte dark surfaces — is 20 m.
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.
- The complete angular-resolution to scan-rate combination matrix (which of 0.08/0.16/0.32 degrees pairs with which of 50/100 Hz).
- 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 and issuing bodies. Certification documents are available on request.
- 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.
