The PTFG 1200m is a compact long-range laser distance detection module that delivers precise measurements from 3 to 1200 meters (at 70% reflectivity) with ±1 m accuracy and 0.1 m resolution. It integrates a 905 nm Class 1 eye-safe laser and UART output, operating on a 3.3 V DC supply. Measuring just 92 × 54 × 33 mm and weighing approximately 60 g, this module is ideal for applications requiring precise long-range distance detection.
