Benewake TFmini-i CAN

The TFmini-i is an enhanced single-point LiDAR sensor based on the TFmini-S model. With improved communication interfaces and a wider input voltage range, it is perfectly tailored to meet the needs of a variety of industrial applications.

It operates using the Time-of-Flight (ToF) principle and delivers reliable, precise, and stable distance measurements.

Specification Notes

• The detection range was determined using a standard white board (90% reflectivity) at 25 °C. Environmental conditions may affect measurement results.
• The detection range was also tested using a standard black board (10% reflectivity) at 25 °C.
• Accuracy was measured using a standard white board (90% reflectivity) at 25 °C.
• The maximum frame rate is 100 Hz. Custom frame rates can be calculated with the formula: 200/n (n is an integer ≥ 2).
• The FoV value is theoretical; actual results may vary.
• The TFmini-i has 5 mm deep mounting holes (non-through), located on the back (4×φ1.6 mm). Use M2 cross-head, round-head, flat-tail self-tapping screws for installation.
