Minimum distance from reflective surfaces
Reflective surfaces in the area of opto-electronic protective devices can indirectly deflect
beams from the transmitter into the receiver. This can cause an object in the protective
field not to be detected! All reflective surfaces and objects (for example material
containers, sheets) must be kept at a minimum distance „a“ . The minimum distance
depends on the distance „b“ between the transmitter and the receiver.
Safety light curtains of the SOLID-2 product line are equipped with an optics of less beam
aperture than required by EN IEC 61496-1, -2. Thus, less distances between reflecting
surfaces and protective field are needed than typically required.
Warning!
Replacing with safety light curtains of different production lines fulfilling the minimum
requirements of the above mentioned standards may request higher distances.
