Overview Manuals Optical Geometry Profile Capture Signal Quality Installation

Features:

  • 73 mm reference distance with 35 mm profile width
  • 3,200 profile points at selectable intervals
  • Single-shot HDR for mixed surface reflectivity
KEYENCE LJ-X8080 projects a blue laser line across the target and returns height profiles to the LJ-X8000 controller.

At the 73 mm reference plane, LJ-X8080 measures a 35 mm X-axis width while accommodating a 41 mm full-scale Z range.

Its single-shot HDR capture helps LJ-X8080 preserve data across surfaces that return different light levels in the same profile.

The KEYENCE LJ-X8080 2D/3D Laser Profiler Sensor Head may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
KEYENCE LJ-X8080 is an LJ-X8000-series 2D/3D laser profiler sensor head that projects a blue laser line and returns height-profile data to the system controller.

At its 73 mm reference distance, LJ-X8080 covers a 35 mm X-axis width and a 41 mm full-scale Z range. The receiver records 3,200 profile points at selectable intervals down to 12.5 micrometres, allowing the controller to reconstruct surface shape rather than report a single distance.

Single-shot HDR on LJ-X8080 captures different reflection levels in one exposure, while the aluminum IP67 housing and specified head cable protect the optical path during installation. The head must be fixed to a metal mounting plate so its measurement geometry remains stable.

Technical notes
KEYENCE LJ-X8080 is the 73 mm reference-distance head in the LJ-X8000 profiler family. It outputs 3,200-point profile data through the connected controller.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
If target position shifts along Z, how does the usable profile width change on KEYENCE LJ-X8080?
KEYENCE LJ-X8080 spans 30 mm at the near side, 35 mm at the 73 mm reference distance, and 39 mm at the far side, so width depends on target height.
Why must KEYENCE LJ-X8080 be fixed to a metal plate before precision checking?
The published operating condition for KEYENCE LJ-X8080 requires metal-plate mounting; verify that support before applying its repeatability and linearity figures.
When can changing the X-axis data interval alter the selected measurement area on KEYENCE LJ-X8080?
On KEYENCE LJ-X8080, the 12.5 µm interval is adjustable, and changing it also changes the X-direction measurement range; interval and field width must be selected together.
How does single-shot HDR help KEYENCE LJ-X8080 capture surfaces with mixed reflectivity?
With KEYENCE LJ-X8080, one exposure records levels from dark to glossy regions, reducing profile loss without combining separately timed captures.
Which optical safety limit applies before aligning KEYENCE LJ-X8080?
KEYENCE LJ-X8080 uses a 405 nm, 10 mW Class 2M laser; do not view its beam through magnifiers, microscopes, telescopes, or other optical instruments.
