XTOF-RM-100 TOF range finder module

The XTOF‑RM‑100 from Excelitas Technologies is a compact, cost‑optimized time‑of‑flight (TOF) range‑finder module engineered to deliver fast, accurate, and reliable 3D distance measurements in an exceptionally small form factor. Built around Excelitas’ proprietary XTOF‑100‑A TOF chip and paired with a highly efficient LED illumination source, the module provides fully calibrated, compensated, and ready‑to‑use depth data straight out of the box.

Designed for developers who need precise ranging performance without the burden of complex optical, illumination, or signal‑processing design, the XTOF‑RM‑100 integrates all critical components into a single, easy‑to‑deploy module. Its advanced ambient‑light suppression enables operation in full outdoor sunlight up to 100 kLux, opening the door to new applications in mobile robotics, automation, and smart environments. With a measurement range from 0.05 to 15 meters, a narrow 0.18° × 0.18° field of view, and more than 500 measurements per second, the module delivers high‑resolution, high‑speed distance data suitable for both dynamic and static sensing tasks.

The XTOF‑RM‑100 also supports seamless integration into robotic ecosystems through an available ROS driver, making it ideal for developers building autonomous systems, safety solutions, or intelligent monitoring platforms. Whether used for gesture recognition, people counting, collision avoidance, or industrial control, the module provides a robust, low‑power, and highly adaptable TOF sensing solution.
