More Information

Overview Manuals Measurement Field Profile Timing Mounting Rules Product Applications

Features:

  • Long-range diffuse-reflection profile measurement
  • Wide X-axis field around a 300 mm reference distance
  • Blue-laser profile capture for rapid inline inspection
LJ-V7300 is distinguished by its 300 mm reference geometry, which positions it for wider stand-off measurements than shorter-range heads in the family.

The head projects a line and captures the target profile across both height and width, supplying profile data to the associated LJ-V controller architecture.

Head selection should account for the changing field width, target surface, required metal mounting plate and the trigger mode needed by the production process.

For KEYENCE LJ-V7300 Sensor Head sourcing, Apter Power can help confirm the exact head, cable requirement and installed measurement geometry.

  • Reference plane: The nominal working distance is 300 mm.
  • Height span: The Z-axis field extends ±145 mm around reference.
  • Near width: The X-axis field narrows to 110 mm at the near side.
  • Far width: The X-axis field expands to 240 mm at the far side.
  • High-speed mode: The minimum documented trigger interval is 16 µs under stated conditions.
  • Advanced mode: The corresponding minimum interval is 32 µs.
  • Data spacing: X-axis profile points are recorded at 300 µm intervals.
  • Mode selection: Choose timing only after confirming the controller functions enabled for the inspection.
  • Metal plate: Install the sensor head on a metal plate as specified.
  • Cable seal: IP67 requires a specified CB-B* sensor-head cable or CB-B*E extension cable to be connected.
  • Ambient range: Operate between 0°C and +45°C.
  • Condensation: Keep relative humidity within the non-condensing boundary.
  • Inline profiling: Measures a continuous cross-section without stopping the production line.
  • Height inspection: Detects surface-height variation inside the documented field.
  • Position inspection: Uses the captured profile to evaluate target location.
  • Non-contact checks: Measures soft or sensitive surfaces without mechanical contact.
Description
LJ-V7300 is the long-range sensor head in the KEYENCE LJ-V7000 high-speed 2D laser profiler family. Its diffuse-reflection geometry uses a 300 mm reference distance and captures an X-axis profile whose width changes with target distance.

LJ-V7300 uses a visible 405 nm blue semiconductor laser and supports rapid profile triggering for inline measurement. Mechanical installation must use the documented metal plate; IP67 applies when a specified CB-B* sensor-head cable or CB-B*E extension cable is connected.

Technical notes
Published repeatability and linearity for LJ-V7300 depend on the manufacturer’s reference targets, measurement area and settings. Do not treat the headline values as unconditional accuracy. Install the head on the required metal plate, confirm the actual target surface and specified lighting conditions, then validate the selected profile mode against the required tolerance.

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.
How does target distance change the usable profile width of LJ-V7300?
The field widens from 110 mm near the head to 240 mm at the far side, with 180 mm at the 300 mm reference plane; design the fixture around the actual target position.
Can the published repeatability of LJ-V7300 be applied to every surface?
No. The value is conditional on the manufacturer’s target and settings, so validate the real material and measurement area before accepting the tolerance.
When is the 16 µs trigger interval available on LJ-V7300?
It is the documented high-speed-mode minimum under specified conditions; advanced-function operation uses a 32 µs minimum instead.
What preserves the IP67 boundary when installing LJ-V7300?
Connect a specified CB-B* sensor-head cable or CB-B*E extension cable; the head alone does not establish the stated sealed condition.
Which ambient-light reference applies when evaluating LJ-V7300?
Use the published maximum of 10,000 lux under incandescent light, measured on white paper at the receiving surface, and revalidate other target or lighting conditions.
How should a warm enclosure be evaluated before accepting LJ-V7300 profile stability?
Apply the documented 0.01% of full scale per °C characteristic over the expected temperature change, keep the head on the required metal plate and validate the actual target.
