LDL-T 100Hz 1mm Accuracy Laser Distance Measuring Sensor

 

LDL-T Laser Distance Measuring Sensor Overview

The LDL-T laser distance measuring sensor is a newly launched high-performance solution for accurate and efficient distance measurement. With a maximum measuring range of 100 meters, precision up to ±1mm, and a frequency of 100Hz, this sensor is ideal for applications that demand both speed and accuracy. Unlike conventional distance modules, the LDL-T offers versatile interface support, compact size, and advanced phase measurement technology, making it a perfect choice for automation, robotics, and industrial monitoring.

Phase-Based Measuring Principle

The LDL-T utilizes the phase-shift measuring principle. This method calculates distance by detecting the phase difference between emitted and reflected laser beams. Compared with time-of-flight sensors, phase measurement provides superior resolution and higher precision at short to medium ranges. The technology ensures consistent accuracy even in environments with variable lighting conditions or reflective surfaces, making the LDL-T a high precision laser distance sensor for demanding applications.
