50m TOF Laser Distance Sensor

The TOFSense F2P is a professional laser distance sensor based on the dTOF technology (Direct Time-of-Flight) with a range of up to 50 meters and an accuracy of ±3 cm. The sensor works with a frame rate of 100 Hz, making it suitable for real-time applications with fast-moving objects. The high ambient light resistance of 100K LUX allows reliable measurements even in direct sunlight. With dimensions of 22.7 × 28 × 13.6 mm and a weight of only 7.5 g, the sensor is compact enough for integration into drones and mobile robots.

Note: The cable colors are reversed – red is GND and black is VCC. Please pay special attention when connecting.
