Made in Germany

The RF70A is an OEM laser module to integrate laser distance measurement capabilities into existing measurement equipment. It is intended for general distance measurements that require extremely fast data acquisition. It provides up to 40,000 centimeter-precise measuring values per second – up to 70 m without a reflector. With appropriate reflectors the RF70A reaches objects at distances up to 270 m.

The OEM laser module RF70A has been optimized for easy system integration. With its 5V power supply and a CMOS-level UART the connection to microcotrollers or SoCs can be done quite easy. Due to the invisible and eye safe laser (905 nm) the Rf70A can also be used in public areas.

The combination of an RF601 for the long range and an RF70A for the close range allows the entire distance range from the harbour entrance to the berth to be covered. In addition, with the increased data rate of the RF601F of 400 Hz, 2D or 3D scanning applications for extremely large areas in geodesy and landscape monitoring can also be realised. Due to the very compact dimensions, the new modules are also suitable for use in drones or UAV applications.
