+86 1535940827535 mm Wide-Field 2D/3D Laser Profiler Sensor Head · KEYENCE LJ-X8000 2D/3D Laser Profiler Series
KEYENCE LJ-X8080 is a wide-field sensor head in the LJ-X8000 2D/3D laser profiler family. Its 405 nm blue laser and 3200-point profile acquisition support inline measurement of height, width, step, gap, warpage and surface shape.
At the 73 mm reference distance, LJ-X8080 covers a 35 mm X-axis width and a ±20.5 mm Z-axis range. The manufacturer documents 0.5 µm Z repeatability and 1 µm X repeatability under specified test conditions.
The head must be paired with a compatible LJ-X controller and cable. Mount it to the required metal plate, maintain the optical stand-off and confirm field of view, target reflectance, laser safety and controller settings during commissioning.

KEYENCE LJ-X8080 captures a 3200-point laser profile for inline dimensional and shape measurement when connected to a compatible LJ-X8000 controller.
KEYENCE LJ-X8080 provides a ±20.5 mm Z range and an X width of 35 mm at the 73 mm reference distance, with width changing toward the near and far limits.
KEYENCE LJ-X8080 uses a 405 nm blue semiconductor laser classified as Class 2M with a documented 10 mW output, so the installation must follow applicable laser-safety controls.
KEYENCE LJ-X8080 is specified at 0.5 µm Z repeatability and 1 µm X repeatability under the manufacturer test conditions, which should not be treated as guaranteed application accuracy without validation.
KEYENCE LJ-X8080 requires a compatible LJ-X controller and approved head or extension cable, with the controller firmware and measurement program matched to the head.
KEYENCE LJ-X8080 requires rigid metal-plate mounting, correct reference distance, unobstructed optical paths, suitable target presentation and environmental conditions within the documented limits.
Provide the complete KEYENCE LJ-X8080 nameplate, controller model, cable length, measurement width and range, target material, mounting arrangement, quantity and destination.
Send the complete model, revision, quantity, destination and nameplate photo so the exact hardware identity can be checked.
