Meskernel PTFS-100-400Hz 100m 400 Hz High Frequency Laser Distance Sensor for Drone/UAV, TOF 905 nm Class I

Overview

Meskernel PTFS-100-400Hz is a high-frequency laser distance measuring device and precision laser distance sensor for drone/UAV, AGV, industrial automation, and security applications. The PTFS pulse TOF laser module measures distance by timing the round-trip of pulsed laser beams. It supports 3–100 m detection range (up to 3–100/150 m per parameter table), measurement frequency 100–400 Hz, 0.1 m resolution, and absolute accuracy ±1 m. The sensor uses a 905 nm Class I laser and offers compact dimensions (43*35*21 mm), low power consumption, and multiple communication interfaces. Features noted include strong anti-jamming ability, support for secondary development, and use indoors or outdoors for speed, displacement, and distance measurement.
