High Accuracy Distance Measurement Sensor Technology
At the core of the LDL-T High Accuracy Distance Sensor is a phase-shift distance measurement principle, which enables stable and reliable distance readings even on challenging surfaces. Compared with time-of-flight methods, this technique provides better repeatability and accuracy, especially at mid-range distances.
The LDL-T offers flexibility in laser emission with two wavelength options:
Red Laser (610–690nm):
Offers high compatibility with standard receivers and optics. It’s perfect for general indoor applications and surface measurements.Green Laser (510–550nm):
With better visibility in daylight and superior performance on dark or shiny surfaces, green laser is the choice for outdoor or high-glare environments.
Laser Sensors for Distance Measurement – Built for Integration
Designed for seamless system integration, the LDL-T supports multiple communication interfaces, including:
TTL / RS232 / RS485 – Reliable wired options for industrial and embedded systems
Bluetooth – For wireless communication, especially in mobile robotics or portable devices
It’s also compatible with a wide range of developer platforms, such as:
Arduino
ESP32
Raspberry Pi
PLC systems
This versatility makes it the ideal high accuracy distance measurement sensor for system developers, engineers, and automation solution providers.
Typical Applications
Thanks to its compact form factor and high precision, the LDL-T is suitable for a wide variety of applications, including:
Industrial automation – Position control, displacement feedback, object detection
