The LJ-X8080 is a KEYENCE 2D/3D laser-profiler sensor head, not a complete profiler system. It requires a compatible LJ-X8000 controller. The Ethernet entry below is the controller/system-level interface from the official controller specification; it must not be read as a standalone Ethernet port on the sensor head. The manufacturer states that accessories shown are illustrative and may not be included.
Standard specifications
| Product model | LJ-X8080 (sensor head) |
|---|---|
| Vision type | laser_triangulation |
| Image sensor | Blue semiconductor laser profiler; 405 nm visible light; 10 mW; Class 2M (IEC 60825-1) |
| Resolution | 3,200 profile data points per profile (line-profile count; not area-image pixels) |
| Working distance | Reference distance 73 mm; Z range ±20.5 mm (41 mm full span); X width 30 mm near / 35 mm at reference / 39 mm far |
| Data interface | Ethernet |
| Ingress protection | IP67 (IEC 60529); manufacturer cable/configuration conditions apply |
| Operating temperature | 0 to +45 °C |
| Weight | Approx. 1.1 kg (1,100 g) |
| Technical extension parameters | Sensor head only; compatible LJ-X8000 controller/system is required. Accessories shown are illustrative and may not be included. |
Additional manufacturer specifications
| X/Z-axis repeatability | X-axis: 1 µm; Z-axis: 0.5 µm. Manufacturer measurement conditions apply (4,096 averages at reference distance; axis-specific standard targets and default settings). |
|---|---|
| Z-axis linearity | ±0.03% of full scale; parenthetical ±0.004% is a representative average example, not a guaranteed limit. Manufacturer target, smoothing and averaging conditions apply. |
| X-axis profile-data interval | 12.5 µm default; configurable from 10 µm. Changing interval also changes X-axis measurement width. |
| Laser spot size | Approx. 44 mm × 72 µm at the reference distance. |
| High-dynamic-range capture | Single-shot HDR. |
| Ambient-light limit | Incandescent lamp: 10,000 lux or less. |
| Relative humidity | 85% RH or less, non-condensing. |
| Vibration and shock resistance | Vibration: 10–57 Hz, 1.5 mm double amplitude, 3 hours each on X/Y/Z axes; shock: 15 G / 6 ms. |
| Housing material | Aluminum. |
| Temperature characteristic | 0.01% of full scale per °C. |
| Profile data semantics | The 3,200-point figure is profile-data count, not camera pixel resolution or frame rate. |
