LDJU 3000Hz Precision Industrial Distance Sensor
High Frequency | Phase-Based | Industrial-Grade Design
Ultrafast & Reliable Industrial Distance Measurement
The LDJU 3000Hz Precision Industrial Distance Sensor is a next-generation industrial distance sensor built for high-speed, high-precision environments. Featuring an impressive measurement frequency of up to 3000Hz (customizable to 10,000Hz), this sensor enables real-time monitoring and control in demanding industrial applications.
With a working range of 0.03 to 20 meters and accuracy between 3–5mm, this high frequency laser distance sensor is ideal for automation, robotics, material handling, and more. It adopts phase-based measurement technology for stability, speed, and precision in every measurement.
Phase-Based Measurement – Speed Meets Accuracy
LDJU utilizes phase-shift measurement technology, which compares the phase difference between emitted and reflected laser signals. This method offers high-frequency sampling with stable accuracy, making it superior for dynamic object detection and high-speed automation compared to TOF or triangulation methods.
Standard Red Laser, Optional Green Laser
Default wavelength: Red laser (610–690nm)
Optional: Green laser (510–550nm) for higher visibility on dark or reflective surfaces
Choose the wavelength that best suits your lighting conditions and target materials.
IP54 Protection – Built for the Industrial World
The LDJU comes housed in a sturdy IP54-rated enclosure, providing protection against dust and water spray. This makes it suitable for semi-outdoor environments, dusty production lines, and automation setups requiring continuous operation.
Multi-Platform Compatibility
LDJU is easy to integrate with both development and industrial control platforms:
Arduino – Great for prototyping, testing, and building entry-level automation systems.
ESP32 – Ideal for IoT applications with built-in Wi-Fi/Bluetooth for wireless distance monitoring.
Raspberry Pi – Used for advanced data logging, cloud control, and AI-based measurement systems.
PLC Systems – Seamless integration with programmable logic controllers for industrial automation lines.
And More – Supports TTL, RS232, RS485, and Bluetooth, offering broad connectivity for any project.
Application Scenarios for the LDJU Industrial Distance Sensor
High-Speed Conveyor Belt Monitoring:
