Benewake TFmini Plus Single-Point Ranging LiDAR
SJ-PM-TFmini Plus-01 A07 Datasheet
1. Product Description
The TFmini Plus is a single-point ranging LiDAR module utilizing the Time-of-Flight (ToF) principle. It is designed for stable, accurate, and high-frequency range detection. Key features include:
- High frequency (up to 1000Hz)
- Small size
- Low power consumption (550mW, with a special mode consuming <=100mW)
- IP65 Enclosure
The TFmini Plus is primarily used in the following application fields:
- Pedestrian detection
- Vehicle detection
- Altimeter
- Robot fall-arrest
