Highspeed OEM module

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.
