FF-SB Installation Manual
Beam diameter is the smallest width that will block a single light beam. The FF-SB12 and FF-
SB14 have a beam diameter of 9,5 mm (0.37 inch). The FF-SB30 has a beam diameter of 4,5
mm (0.177 inch). The combination of the beam diameter and center distance gives the FF-
SB12 (see figure 1-6) a resolution of 22 mm (0.87 inch), the FF-SB14 a resolution of 35 mm
(1.38 inches) and the FF-SB30 a resolution of 30 mm (1.18 inches).
The FF-SB15 has a 235 mm (8.5 inches) gap between the sets of its beams and is
considered suitable for perimeter guarding only.
IMPROPER POINT-OF-OPERATION PROTECTION
Do NOT use FF-SB15 Series light curtains in point-of-operation applications.
Failure to comply with these instructions will result in death or serious injury.
Figure 1-6 Light Curtain Resolution
IMPROPER INSTALLATION OF FF-SB SERIES LIGHT CURTAIN
• Because the emitter and receiver units must have the same resolution and protected height
to operate, DO NOT use FF-SB30 emitter with FF-SB14 receiver or vice versa.
• DO NOT use FF-SB12 or SB14 with FF-SB15 emitters or receivers.
Failure to comply with these instructions could result in death or serious injury.
Protected Height
Protected height is the height from the top of the uppermost light beam to the bottom of the
synchronization beam (see figure 1-5). The synchronization beam is part of the protected
height.
Synchronization
The FF-SB Series emitter is optically synchronized by an infrared light beam sent from the
receiver to the emitter. The beam keeps the emitter and receiver in synchronization. External
wiring between the emitter and receiver or through a third control unit is not needed. To
simplify maintenance and inventory, the emitter and receiver are not matched.
