SICK TiM LIDAR Teardown

by on January 8, 2024

Hi all
A few years ago I did a teardown of the classic LMS 291 “brick” that was common on many early robots. Now I had the chance to open up a newer much smaller TiM-100 LIDAR sensor. Lets see how things have changed.

See the video below to learn about the SICK TiM sensor.


To look back at the old large almost indestructible LMS teardown, click here. Then look below to see a modern smaller and more capable LIDAR sensor.

The SICK TiM-100
Rear of the SICK TiM-100 showing the connector. Also note the black vertical section that protrudes from the lens. That holds the encoder circuit board that we will soon see.
Starting to open
Got the sensor open. It was pretty easy after removing the 4 screws. The plastic mates together nicely to keep dirt and liquids out.
Another view showing the cable with connector going to the top encoder.
Looking down into the bottom of the sensor that contains the processing circuitry and laser.
Looking into the top black lens section. The mirror and guide for the laser are visible. The white connector is also visible that connects to the optical encoder mounted near the top of the sensor. I like how the encoder disc is a notched piece of plastic and not a typical thin disk with black lines. You can also see a little bit of a white epoxy of some type behind the mirror on the back of the top surface.

I hope you enjoyed this view into the TiM laser scanner. I enjoyed taking a look into the sensor. Fortunately or unfortunately I did not take those internal components out since I still need to use this sensor and I dont want to destroy it.

Did you enjoy this teardown? Leave comments below for other items you would like to see inside of.
