Measuring Type	Diffuse-remission measuring type (no reflector required)

Overview

DLD-50G belongs to DAIDISIKE's laser scanning lidar range and is classified as a 2D single-line, diffuse-remission measuring type scanner. It is intended for integrators who need contour or profile data from objects, materials, or moving equipment that cannot practically carry a reflective target.

Unlike single-point distance sensors, it rotates a single scan plane to build a distance profile across a cross-section on every revolution. Its diffuse-remission design reads distance directly from the natural, non-cooperative surface of the target, so no reflector, reflective tape, or corner-cube target needs to be installed.

Features & Benefits

No Reflector Required

As a diffuse-remission measuring type, the DLD-50G reads the return signal directly from the object's own surface reflectivity. This eliminates the installation and upkeep of reflector plates or cooperative targets on the target object.

Full Cross-Section Profile per Revolution

A single scanning line outputs the distance distribution across an entire plane on each rotation. This delivers far more scene information than a single-point distance sensor capturing the same instant.

Works on Non-Cooperative Objects

The reflector-free operating principle makes the DLD-50G applicable to bulk materials, moving vehicles, or irregular objects where mounting a cooperative target is impractical or impossible.

Compact Rotating-Head Design

Product photos show a compact enclosure with a rotating scan head assembly and a status indicator strip, consistent with a self-contained rotating 2D scanning lidar unit.

Applications

Contour Measurement Without Reflective Targets — Where objects cannot carry a reflector, the DLD-50G measures the object's own surface directly, since no cooperative target is required.

Distance Profiling of Bulk Materials — The diffuse-remission measuring principle makes it suitable for profiling natural surfaces such as bulk material piles that are not reflective targets.

Position/Contour Sensing on Moving Equipment — For moving objects that cannot mount a reflector, the reflector-free operation allows contour or position sensing directly off the equipment surface.

2D Scene Profiling Beyond Single-Point Distance — Where a single distance reading is not enough, the single-line scan outputs a full cross-sectional distance profile on every rotation.

Models & Ordering Information

DLD-50G Series

DLD-50G

Currently the only model listed for this series; sub-variants for output type, range, and supply voltage are not documented yet.

How to Select

DLD-50G is currently the only model listed for this series; no sub-variants for output type, range, or supply voltage are documented yet.
The relationship between DLD-50G and DLD-50D (sister model vs. different-generation product) has not been confirmed by the factory, so no comparison is published between them.

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

Using DLD-50G as the protective sensor in a machine safety function to stop machinery and protect a person

Why not: No safety rating, no OSSD output and no certification is published for DLD-50G. Only its scan type (2D single-line) and its measuring principle (diffuse remission, no reflector required) are confirmed. A device with no published safety rating cannot be the protective device in a safety function.

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.

A project that requires a committed detection range or ranging accuracy

Why not: We do not publish a detection range, ranging accuracy or angular resolution for DLD-50G, because the factory has not confirmed them. We will not quote a number we cannot stand behind.

Use instead: Ask us for the missing figures before you specify this model, or use a model whose range and accuracy are published — DLD-50D (50 m @90% remission, plus or minus 20 mm) or DLD-100D (100 m @90% reflectivity, plus or minus 20 mm).

You need a specific output or interface type to integrate with a given controller

Why not: The output interface and communication protocol of DLD-50G are not documented in any source we hold.

Use instead: Confirm the interface with us before specifying, or choose a model with a published interface such as the Ethernet 100BASE-TX documented for DLD-50D and DLD-100D.

Outdoor, washdown or dusty deployment where an ingress rating is required

Why not: No IP rating is published for DLD-50G.

Use instead: Confirm the ingress rating with us before outdoor or washdown deployment, or use a model with a published IP67 rating such as DLD-50D or DLD-100D.

Deployment in an occupied space where the laser must be confirmed eye-safe under a recognised class

Why not: The laser wavelength, optical power and safety class of DLD-50G are not published.

Use instead: Request laser-class confirmation from us before deploying near people, or use a model with a published Class 1 905 nm source such as DLD-50D or DLD-100D.

Frequently Asked Questions

What does "diffuse-remission measuring type" mean for the DLD-50G?

It means the sensor is designed to measure distance by reading the diffuse reflection (remission) from the natural surface of the target object itself, rather than requiring a reflector, reflective tape, or corner-cube target mounted on the object.

Does the DLD-50G require a reflector or cooperative target to operate?

No. As a diffuse-remission measuring type 2D lidar, it is designed to work off non-cooperative, natural surfaces without an installed reflector.

Is the DLD-50G a single-point sensor or a scanning sensor?

It is a 2D single-line scanning lidar. It rotates a single scan plane to output a distance profile across a cross-section, rather than a single fixed-point distance reading.

What certifications does the DLD-50G carry?

Certification documents are available on request.
