## GRF-500 Laser Rangefinder — Produktbeschreibung

The **GRF-500** is a compact, ultralight, and energy-efficient sensor that utilizes the *time-of-flight* principle to measure distance by emitting a rapid succession of laser pulses, which are reflected by target objects and immediately processed.

It uses **905-nanometer laser technology**, ensuring optimal performance at an affordable price, while meeting **class 1M eye safety standards**. The GRF-500’s accuracy is not affected by the color or texture of the target or object surface, nor by the angle of incidence of the laser beam. It is virtually immune to background light, wind, and noise, making it an ideal sensor for outdoor use.

Configurable features allow users to set device parameters on the fly – catering to varying use cases without the need to ground the sensor for reconfiguration.

Measuring a mere **35 mm × 31 mm × 21 mm**, this sensor is meticulously designed for seamless integration into space-constrained gimbals, ensuring versatility without compromise. Weighing just **10.7 g**, the GRF-500 sensor stands as the epitome of ultralight design, making it the ideal choice for gimbals used in demanding applications with strict weight constraints.
