LDL-T Mini Size High Accuracy Distance Sensor

-Compact Laser Sensor for Demanding Precision Tasks

Compact. Precise. Versatile.

The LDL-T is our latest addition to the high accuracy distance sensor product line — a compact, lightweight, and highly adaptable sensor developed to meet the increasing demand for precise non-contact distance measurement in space-constrained environments.

Despite its miniature form factor, the LDL-T packs powerful performance. With a maximum measuring range of 80 meters, an accuracy of up to ±1mm, and a measurement frequency of up to 30Hz, it provides real-time, reliable data for a wide variety of industrial, research, and embedded system applications.

Parameters

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

• Robotics – Real-time spatial sensing, obstacle detection, localization

• Material handling – Forklift guidance, conveyor alignment, package detection

• Smart devices – Embedded measurement systems, distance-triggered actions
