Laser Profilers and 3D Measurement Sensors

Laser profilers and 3D measurement sensors project a laser line onto a target and use triangulation to measure surface shape, height, defects, and dimensions in real time. They are used for inline inspection, robotic guidance, sorting, and quality control where 2D vision falls short.

Enicstra stocks Keyence LJ-X and LJ-V series profile sensors, SICK Ranger3 and TriSpector cameras, Cognex DS-series 3D laser displacement sensors, Micro-Epsilon scanCONTROL line lasers, and similar systems from other manufacturers. Coverage includes both current models and end-of-life part numbers used in installed automation lines. Every sensor is bench-tested before shipment with our 12-month functional warranty.

These sensors require matching controllers, lenses, and software licenses for full operation — confirm what's in your existing installation before ordering. Send the OEM model number along with the controller part number when requesting a quote; most replies within 1–2 business days.

Choosing Laser Profilers and 3D Measurement Sensors components

3D measurement sensors are not interchangeable across brands or even across generations within the same brand. The laser optics, sensor geometry, and controller firmware are tightly coupled — replacing only the sensor head without matching the controller usually results in a non-functional system.

Specifications to confirm before ordering:

Measurement range — Z-axis (height) and X-axis (line width)
Resolution requirement (Z-axis and X-axis)
Standoff distance from sensor to target
Profile measurement rate (Hz) required by your line speed
Target material — diffuse, reflective, transparent, or mixed
Laser class (1, 2, 2M, 3R) — affects safety requirements at the workstation
Controller compatibility — head and controller must match generation and firmware
Software license — application-specific licenses (measurement, inspection, robot guidance)
Communication interface (GigE Vision, EtherNet/IP, Profinet)

Common applications:

Weld seam inspection: high-resolution profile sensors mounted post-weld
Tire and rubber inspection: 3D profilers for defect and dimensional measurement
Lumber and panel grading: long-range profile scanners covering full panel width
Robotic bin picking: 3D snapshot cameras returning point clouds for path planning
Food processing: washdown-rated profilers for portion measurement

If you're replacing a discontinued profiler model, confirm whether the replacement requires a controller upgrade and new software license. Send the full part numbers of head, controller, and software to get an accurate quote.

Related categories Frequently asked questions

Can you supply discontinued Keyence LJ-V, SICK Ranger, or Cognex DS sensors?

Yes — end-of-life 3D laser sensors and matching controllers are common requests, particularly for inspection lines built around a specific sensor generation. Send the model numbers (head and controller) and we'll check supplier-network availability.

Does the sensor work without the original controller?

Usually not. Most 3D laser sensors are tightly coupled to their controllers — the controller does the triangulation calculations and image processing. Verify that you have a compatible controller before ordering a head-only replacement.

What about software licenses?

Application software is typically licensed separately and tied to the controller hardware. A replacement sensor head usually doesn't need a new license, but a controller replacement often does. Send your existing controller's part number and serial number with your quote request.

Are these new, surplus, or used?

Most inventory is new-old-stock — unused, often in original packaging. Some legacy sensors come from tested system removals. Each product page lists condition where known.

Can I cross-reference to another brand?

3D laser sensors generally cannot cross-reference between brands because the controllers and software are vendor-specific. If you're considering a brand change, expect a complete system replacement (sensor + controller + software) rather than component-level substitution.
