High accuracy laser triangulation displacement sensor with 30 mm measuring distance and compact structure

Sensor used for substrate warpage detection, lead frame overlap inspection and gasket presence detection

High Accuracy 0.01mm PNP Output Laser Triangulation Displacement Sensor 30mm Measuring Distance

This high-accuracy laser triangulation displacement sensor is designed for precise measurement, positioning, and detection tasks in industrial automation. Using a high-precision CMOS image sensor combined with an optimized processing algorithm, it achieves repeat accuracy as fine as 5 µm and a beam diameter of only 120 µm, ensuring stable measurement of small or complex targets. With a 30 mm center measuring distance, ±35 mm range, and PNP output, the sensor integrates easily into automated equipment for applications such as flatness detection, electronic component inspection, alignment, and presence detection. Its compact structure and 10–30 VDC power compatibility make it suitable for a wide range of industrial environments.
