The OSP/OEP high performance photoelectric sensors from Di-Soric offer special features. The beams don’t just attempt to detect tiny parts, but strive for as safe an operating mode as possible in rough ambient conditions. Examples include use in the timber processing industry, monitoring doors and gates and detecting objects in heavily polluted areas suffering from general contamination. The OSP 50 photoelectric transmitter offers the option of setting the transmission performance with a 4-way potentiometer to allow for optimum adaptation to the detection task in hand. Furthermore, the innovative two-transmitter principle gives the user a changeover switch for choosing between a short-range transmitter with a broad reflected ray angle for very simple alignment and an alternative transmitter with narrow reflected ray angle for larger ranges.
