The EY-1501A series is a compact, cylindrical semiconductor laser rangefinder module operating at an eye-safe wavelength of 905±10nm. Designed for large targets, it offers a range capability of 10 to 800/1000/1200/1500 meters with a ranging accuracy of ≤1+L×0.25% (L being the measuring distance) and a resolution of 0.1 meters. The 905nm laser rangefinder module features a lightweight (≤20g) and small-volume design (≤φ23mm×46mm), making it highly portable and suitable for various applications. It supports single or continuous (≥1Hz) ranging modes, has low standby power consumption (≤0.6W), and operates within a voltage range of 2.5V to 3.5V. With an integrated design, strong shock resistance, and multiple installation options, it is ideal for handheld devices, UAVs, small pods, and other scenarios requiring precise short-distance measurement.
