The Keyence high-speed LJ-G Series 2-D laser sensors accurately measure the surface profile of targets in the x and z directions. The unit features a high-speed sampling of 3.8 ms and accuracy of ±1% full-scale in the z axis. It can perform eight-point measurements, making 100% inspections possible. Five sensor-head types ranging from 15 mm (0.59 in) to 200 mm (7.9 in) can handle tight specifications for various applications. The all-in-one controller allows easy setup on screen or with the optional LJ-G Navigator software. Two sensor heads may be connected to one controller.
