The DLD30T-5N is an economical industrial laser ranging sensor designed for precise, non-contact distance measurement in demanding environments. It features high performance with adjustable sampling frequencies from 3-30Hz, IP67 sealing against water and dust, and Class 1 laser safety. With detection ranges up to 20m (under 70% reflectivity), it supports RS485/Modbus protocol that connects directly to PLC systems and other industrial equipment.
The DLD30T-5N series industrial laser ranging sensor offers a cost-effective solution for high-precision distance measurement. It controls the laser ranging module at frequencies between 3-30Hz, making it versatile for various automation needs. Key features include a compact design (55x55x51mm), lightweight construction (85g), wide operating temperature range (-25°C to 60°C), and strong ambient light resistance (up to 20K lux). It provides reliable performance with response times as low as 33ms at 30Hz, adjustable minimum response from 0-1000ms, and laser wavelength of 905nm. 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 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. This method ensures high accuracy across different reflectivities (e.g., ≥20m for 70% reflectivity targets, ≥8m for 10% reflectivity, and ≥4m under 20K lux daylight). The sensor supports RS485/Modbus communication for data transmission, with configurable baud rates (4.8Kbps to 115.2Kbps) and USB-to-serial conversion via FT232. It also allows zone segmentation (16 segments × 4 groups in 4 areas) and outputs via 48 PNP/NPN channels (including 3 for laser power and 1 for fault indication), enabling real-time integration with control systems.
The DLD30T-5N is a 2D obstacle avoidance LiDAR rated for perimeter coverage up to 40 m. Effective range depends on target reflectivity: ≥20 m on 70% reflective targets, ≥8 m on 10% reflective targets, and ≥4 m in 20K lux daylight. Its 3–30Hz scanning frequency makes it suitable for outdoor perimeter LiDAR and AGV/AMR obstacle avoidance.
The DLD30T-5N is an economical industrial obstacle avoidance and perimeter-security LiDAR, not a certified IEC 61496-3 Type 3 safety device. It uses a 905 nm Class 1 eye-safe laser and supports protective/warning-style zone segmentation, but for personnel safety functions requiring a safety-rated scanner you should select a dedicated certified unit.
The scanner supports flexible zone segmentation — 16 segments across 4 groups in 4 areas — letting you define multiple warning and protective fields around a perimeter or mobile robot. Detection events are reported through 48 PNP/NPN output channels (including laser power and a fault indication line), so you can map each field directly to gate, alarm or AGV stop logic.
The DLD30T-5N outputs over RS485 using the Modbus protocol with configurable baud rates from 4.8 Kbps to 115.2 Kbps, and offers USB-to-serial conversion via an FT232 chip for setup. It also drives 48 PNP/NPN switching channels, wiring directly into PLCs, gate controllers and AGV/AMR navigation systems.
Yes. With IP67 protection, a −25°C to 60°C operating range and up to 20K lux ambient-light resistance, the DLD30T-5N suits outdoor perimeter LiDAR, parking and gate applications. As an economical industrial scanner it is a cost-effective alternative for non-safety-rated obstacle avoidance tasks where a full SICK or Pilz safety scanner is not required.
