Resolution

FF-LS Series safety light curtain resolution (sometimes called minimum object sensitivity) is the minimum object size that
will always interrupt at least one light beam when it enters the sensing field. Anything entering the sensing field equal to or
greater than this minimum size will be detected. Resolution is not affected by scanning distance or dust accumulation. The
FF-LS Series does not have a sensitivity adjustment.
Two factors determine the resolution of the safety light curtain: beam center distance and light beam diameter (see Figure 2-5).
FF-LS has a 30 mm and 14 mm resolution.
