CMOS Laser Displacement Sensor LD-A Series

CMOS Laser Displacement Sensors

LD-A Series

LD-A series is a compact and lightweight algorithm-based CMOS laser displacement sensor designed to meet a wide range of application needs. Whether it is height difference measurement, positioning, warpage deformation measurement, feedback loop control, or thickness and width measurement, the LD-A series can provide low-cost and accurate measurement results at low cost to meet different application needs.

Fitted with a precise CMOS image sensor and a unique algorithm Thanks to a precise CMOS image sensor and unique algorithm, make it is possible to perform highly precise measurements in the order of 1/1000 mm (1μm) 0.00004 inch.
ACG Laser + New optical components The LD-A series automatically controls and optimizes laser power based on the reflectivity of the target. Extra large CMOS components improve signal resolution. As a result, stable measurements can be made on virtually any target, from black rubber to highly reflective metal surfaces.

Remote updates maintain newest performance

Teaching, setup and monitoring are made easy with the intuitive LED screen. Three buttons is all it takes to fully utilize the innovative features of the LD-A Series

Applications

Fixed mount barcode scanner
