Import 905nm Laser Rangefinder-Da1501a — Buy in wholesale FOB from Supplier in China

The DA1501A is a 905nm pulsed laser rangefinder module designed for non-contact distance measurement in industrial, surveying, and outdoor automation contexts. The specified maximum measuring range reaches 1500 meters for large targets, with a blind area of 10 meters or less that defines the minimum detectable distance. Range accuracy is stated as plus or minus 1 meter for distances below 300 meters, which meets the demands of civil engineering layout and forestry inventory applications. The 905nm centre wavelength sits within the near-infrared band, offering good atmospheric transmission and eye-safety classification advantages over shorter wavelengths for many outdoor scenarios.

The device employs a user interface intended for rapid field operation, suggesting integration into handheld instruments or mounted surveying equipment rather than purely embedded OEM applications. Signal processing architecture and detector type are not detailed in the source data; typical industry implementations at this wavelength use avalanche photodiode (APD) receivers with time-of-flight (ToF) calculation. Beam divergence, pulse repetition frequency, and receiver aperture diameter are critical parameters that determine real-world performance in varying light and weather conditions. The housing and optical window material specifications are not stated; aluminium alloy bodies with coated glass windows are common in this product category.

Primary applications include civil engineering surveying, architectural measurement, forestry resource assessment, and outdoor recreational rangefinding. Institutional buyers encompass construction contractors, government surveying departments, and equipment integrators building specialised measurement tools. The supplier notes flexible minimum order quantities but does not quote specific figures, and references ISO and CE compliance without certificate numbers or scope. Shipping terms FOB and CIF are mentioned as available options. Buyers should confirm whether the quoted range and accuracy figures apply to standard reflectivity targets or corner-cube retroreflectors, as this dramatically affects achievable performance.

DINGYANG OPTOELECTRONIC TECHNOLOGY (SHENZHEN) CO., LTD is located in Shenzhen, China, a major hub for optoelectronic and laser product manufacturing. The supplier holds a voyage trust tier and an organic supplier tier classification. No response rate or average response hour data is available, which limits assessment of communication reliability through this channel.

The company profile does not disclose year of establishment, factory floor area, employee count, annual revenue, research and development headcount, or specific historical projects. No ISO certificate numbers, CE directive compliance details, or patent information are verifiable from the present data. Buyers should request direct evidence of quality system registration, laser product safety certifications, and reference installations before placing volume orders.
