The RF41 is an OEM laser module to integrate contact-free laser distance measurement capabilities into existing measurement equipment.It is an optoelectronic distance measuring device for industrial applications with an analogue interface. The OEM laser module RF41 distinguishes itself through high precision as well as high independence from the surface of the measuring object. The red, visible laser
beam allows for easy alignment. Compared to the industrial laser distance measurement gauge LDM41A only the housing is omitted.
