LDL-S USB Small Laser Distance Sensor
– High-Precision Measurement in a Compact Form
The LDL-S USB Small Laser Distance Sensor is a next-generation OEM solution designed for engineers and developers seeking a balance between compact size, superior accuracy, and high-speed measurement. This small laser distance sensor offers a measuring range of up to 80 meters, accuracy within 1mm, and a maximum measurement frequency of 30Hz, making it ideal for dynamic applications that demand fast, real-time feedback.
Designed with flexibility in mind, the LDL-S is a standout choice for Laser Distance Sensor OEM applications. It comes equipped with a USB interface for plug-and-play use and supports a wide variety of communication interfaces such as TTL, RS232, RS485, and Bluetooth, ensuring seamless integration into new and existing systems. Whether you are developing a smart industrial device, a robotics application, or a distance monitoring solution, the LDL-S delivers the performance and adaptability you need.
Compact but Powerful
Despite its small footprint, the LDL-S USB Laser Distance Sensor is built for performance. It features a full-metal housing for enhanced durability and electromagnetic shielding, along with a glass optical lens that ensures high transmission efficiency and long-term stability. Its small size allows it to be embedded in space-limited environments such as robotic arms, industrial automatic, or compact enclosures, without compromising functionality.
Precision Measurement Based on Phase Shift Technology
The LDL-S uses phase-shift laser distance measurement technology. This method works by modulating the emitted laser beam and calculating the phase difference between the emitted and reflected signals. This approach allows for consistent millimeter-level accuracy, fast measurement speeds, and excellent stability over medium distances. It also offers higher resistance to environmental noise compared to time-of-flight (TOF) or infrared reflection methods. Learn more about the principle of ranging.
