The DLD30T-5N is an economical industrial laser ranging sensor designed for precise, non-contact distance measurement in demanding environments. It features an adjustable 10–30Hz scan rate, IP67 sealing against water and dust, and a 905nm Class 1 eye-safe laser. The factory parameter table rates detection at 30m on 90%-remission targets and 10m on dark 10%-remission targets, with ±30mm ranging accuracy across a 270° scan. Measurement data is transmitted over a 100BASE-TX Ethernet interface, so it connects directly to industrial PCs and navigation controllers.
The DLD30T-5N series industrial laser ranging sensor offers a cost-effective solution for high-precision distance measurement. Its motor speed is configurable so the point-cloud frame rate can be set anywhere between 10Hz and 30Hz, with a minimum angular resolution of 0.08° and selectable 1/2/4/8-point cloud data merging. Key features include a compact design (50 × 50 × 76mm), lightweight construction (148g), an operating temperature range of −10°C to +55°C (storage −30°C to +75°C), humidity below 80%, and strong ambient light resistance (above 50,000 lux). It runs from a DC12–24V supply at 2W (0.21A at 12V typical), starts up in under 10 seconds and uses a 905nm laser. This sensor is ideal for industrial automation, robotics, AGV/AMR systems, gate controls, and parking facilities, ensuring accurate ranging even in challenging conditions like varying reflectivity or daylight exposure.
The DLD30T-5N is a measurement/perception LiDAR, not an IEC 61496 certified safety component; do not use it as the sole means of personnel protection. No Type, SIL or PL rating is published for this model.
The DLD30T-5N operates on the Time-of-Flight (ToF) laser ranging principle. It emits a pulsed laser beam (905nm wavelength, Class 1 safe) toward the target. The sensor measures the time it takes for the light to reflect back from the target and return to the receiver. Distance is calculated using the formula: Distance = (Speed of Light × Time of Flight) / 2. Because the returned signal strength depends on the target surface, range is rated per remission: 30m on 90%-remission targets and 10m on dark 10%-remission targets, with ±30mm accuracy — even a white board at 30m is held to ±30mm by the TOF timing circuit, which is where this design outperforms triangulation-based radars. Rotating the module sweeps a 270° plane, and every scan point (distance plus angle) is streamed over the 100BASE-TX Ethernet interface, so navigation, SLAM and mapping software receives raw point-cloud data rather than pre-processed switching signals.
The factory parameter table rates the DLD30T-5N at 30 m on targets of 90% remission (reflectivity) and 10 m on dark targets of 10% remission. Always size an installation on the worst-case reflectivity of the objects you actually need to see — dark clothing, black bins and matt rubber sit close to the 10% figure. Ranging accuracy is ±30 mm across a 270° scan.
No. The DLD30T-5N is a measurement/perception LiDAR for obstacle avoidance and area scanning, not a certified IEC 61496-3 Type 3 safety device, and no Type, SIL or PL rating is published for it. It uses a 905 nm Class 1 eye-safe laser, but where a person must be protected by the scanner you must specify a certified safety laser scanner and calculate the field per ISO 13855.
Angular resolution is adjustable down to a minimum of 0.08°, which keeps the point cloud dense enough to resolve slim objects such as posts, shelf legs or a person's legs at distance. Scan rate is adjustable from 10 Hz to 30 Hz: lower rates give denser points per rotation for static measurement and mapping, higher rates give faster refresh for moving equipment. Point-cloud data merging of 1/2/4/8 points is also selectable.
The DLD30T-5N transmits measurement data — distance and angle for every scan point — over a 100BASE-TX Ethernet interface, so it feeds navigation, SLAM and mapping software directly rather than driving switch contacts. Start-up time is under 10 s. If your control system needs plain switching outputs instead of point-cloud data, the DLD05A3 (5 m) and DLD20A5 (20 m) NPN/PNP series are the correct choice.
It is IP67-rated with ambient-light immunity above 50,000 lux, an operating range of −10 °C to +55 °C (storage −30 °C to +75 °C) and humidity below 80%, which suits dusty, washdown-exposed and sheltered outdoor installations. As an economical industrial scanner it is a cost-effective alternative for non-safety-rated obstacle avoidance and measurement tasks where a full SICK or Pilz safety scanner is not required.
