Design, innovation and technology. These are the messages conveyed by the new range of photocells, that perfectly combine style, functionality, practicality, safety, ergonomics and functionality. The possibility of orienting the infrared beam in the DESME A.15 O model allows quick and easy installation of the photocells even on walls or columns that are not aligned with each other, thereby saving time and ensuring a neat and perfect installation. The infrared signal generated by DESME A.15 O is encoded and synchronised so that each receiver installed can receive information only from its associated transmitter, thus eliminating any possibility of blinding of the photocells. Pair of self-aligning photocells. Range 30 m. Power supply 24 v ac/dc.
