Optical data transmission

Data within a network is transferred in different ways. Optical data transmission photoelectric sensors use the "air" medium to transfer data invisibly, contact-free and free from wear over a distance of up to 300 m. This is a leading technology in plant engineering and combines efficiency with cost effectiveness.
