Omron F3SG series User Manual page 79

To enable the muting state, D3 and d2 must satisfy formulas (3) and (4), respectively.
This distance must prevent the muting state from being enabled by a person passing through the
muting sensors. Also, install the F3SG-RA and muting sensors so that each workpiece passes through
all muting sensors before the next workpiece arrives at the first muting sensor.
