Today, as the wave of intelligence sweeps across all industries, logistics, as the lifeblood of the modern economy, its precise perception and efficient collaboration are directly related to the core competitiveness of enterprises. Traditional manual operations and extensive management have become unable to meet the demands of market competition. Digital solutions that are "precise, efficient and reliable" have become the key to breaking the deadlock
The PDG series of laser distance sensors, which focus on long-distance precise measurement, inject new potential into the intelligent transformation of the logistics industry with their outstanding perception performance.
| Model Specification | Measuring Range (3M High-Reflective Film) | Linear Accuracy | Repeatability | Beam Diameter |
| PDG-PM35DHIUR | 150mm...35m | ±10mm | 4mm | about Ø25mm@35m |
| PDG-PM50DHIUR | 150mm...50m | ±10mm | 5mm | about Ø50mm@50m |
| PDG-PM100DHIUR | 150mm...100m | ±15mm | 8mm | about Ø100mm@100m |
• Output mode: It features dual switch quantities (NPN/PNP switchable), analog quantities (4-20mA/0-10V), and RS485 communication. Protocol conversion can also be achieved through an EtherCAT module, making it easy to connect with various PLCS and control systems.
• Safe and reliable: It adopts Class 1 safety laser (660nm red light), which is safe for the human eye.
• Digital display design: The design of display screen + buttons allows for the selection of different output mode Settings, analog quantity mapping, communication Settings, laser off and other functions, making debugging convenient and fast. • Durable and sturdy: With an IP67 high protection rating and a zinc alloy casing, it is not afraid of the harsh environment in industrial sites.
01 Detection of the operating position of stacker cranes
Installing a PDG long-distance laser distance sensor on the stacker crane can directly digitize the position of the stacker crane in three-dimensional space. Through a closed-loop control system, it can drive the stacker crane to quickly, accurately and smoothly reach any target point in the transverse and longitudinal directions, thereby ensuring the safe, efficient and reliable operation of the equipment.
02 Anti-collision detection in the three-dimensional warehouse
When multiple shuttle vehicles are running on the same track, collision prevention is a core safety challenge. The PDG series long-distance laser distance sensor, with its outstanding background suppression, anti-mutual interference and super strong environmental light immunity, can accurately identify real obstacles, effectively prevent misjudgment, and build a reliable anti-collision protection for the coordinated operation of multiple vehicles.
03 Automatic navigation vehicle empty cabin detection
In the empty cabin detection system of autonomous navigation vehicles, the PDG series laser distance sensor is the core for achieving precise spatial perception. Compared with diffuse reflection photoelectric sensors that can only make "presence/absence" judgments, PDG can precisely measure the absolute distance to the target. This not only eliminates misjudgments caused by differences in the color or shape of goods, but also upgrades simple occupancy detection to precise warehouse location data collection, providing key data support for the intelligent decision-making of the warehouse management system.
The future of intelligent logistics begins with every precise perception and decision.
The Lanbao PDG series laser distance sensor is not only a high-precision measurement tool but also the "intelligent eye" of the digitalization of the logistics system. It redefines spatial perception with the precision of light. With stable and reliable performance, we safeguard the efficiency and security of the logistics system. From the millimeter-level (mm) positioning of stacker cranes to the intelligent anti-collision of shuttle vehicles, and then to the precise picking and placing of AGVs - the PDG series is injecting certainty and reliability into every link of smart logistics with its outstanding perception capabilities.
Choose Lanbao, and with vision, steer change; with precision, empower the future.
