Gocator Displacement Sensors

For High-Speed 3D Inline Inspection

Gocator displacement sensors are non-contact laser distance measurement devices that are ideal for determining 3D thickness, height, and surface roughness. The sensors operate at speeds up to 32,000 Hz and ideal for closed loop control or inline inspection of manufactured parts. These sensors are available in various pre-calibrated models for different measuring ranges and resolutions and include built-in support for encoders and multi-sensor synchronization to support demanding inspection needs.


Ideal for real-time closed-loop automation, Gocator displacement sensors operate at exceptionally high speeds. They are ideal for in-line inspection, non-contact dimensional measurements, such as height and thickness, or surface roughness. Important features include:

  • Pre-calibrated and ready to measure
  • Scalable to a synchronized multiple sensor network
  • Small footprint
  • Set-up and control via a web browser
  • Rich I/O and PLC support
  • Open source SDK

High-speed performance

Gocator 1300 series displacement sensors are built on the same platform to deliver high-speed performance centered on the ease of use and flexibility Gocator is known for. The sensors provide highly accurate results suitable for closed loop control. They feature a scanning rate of up to 32,000 Hz.

Measurement Ranges

Every production facility has its unique set of requirements and challenges. Gocator displacement sensors come in a variety of models to measure scan targets of different sizes. Select the model that best suits your needs.

Mounting Options

Top or side mounting options are available to accommodate tight and confined spaces in production facilities.

Laser Class

Gocator displacement sensors come in various laser power classes to compensate for various ambient lighting conditions and darker part surfaces. A stronger laser power class would be best suited for an environment where lighting conditions are brighter than normal.

Industry Solutions


Inline inspection can make a big difference in production quality and line efficiency. The built-in measurement tools provide essential feedback for assembly and quality control processes that ensure a well-built final product.



With an extensive set of built-in tools, PLC connectivity, and an open-source software development kit (SDK), LMI sensors are integrated easily into existing systems to solve inline 3D measurement and control challenges.


Rubber and Tire

Gocator enables you to inspect rubber extrusion shapes, detect tire bulge and dent, set pass/fail conditions, and solve applications from extrusion to final runout that guarantee product performance.



Leveraging LMI's unique RoLine technology, Gocator measures pavement roughness with superior ambient light handling and ride quality at highway speeds, regardless of outdoor conditions and pavement geometry.


Wood Processing

Gocator delivers high-density 3D shape for optimal log and board recovery. Machine builders of edger, trimmer, and planers can easily detect and quantify knots, checks, stain, and other surface defects that affect cutting decisions and product value.


Gocator is ideal for inspecting small parts such as circuit boards and solder pads, detecting defects and setting pass/fail quality control conditions in a variety of electronics manufacturing applications.
