Unsuitable Application Scenarios (Limitations of RE Series)

1. Processes requiring material passing through protective area (Muting function unavailable; machine stops when any workpiece passes, F3SG-SR series recommended instead)

3. Long-term vehicle & large workpiece access passages (Muting function mandatory to avoid frequent unexpected shutdowns)

Response Time Parameters of OMRON F3SG-4RE1630P30

1. Maximum Response Time: 9 ms
2. Supplementary Explanation:

This value refers to total full response duration for the complete set (transmitter + receiver) to cut off OSSD safety outputs

This model has 1630mm protective height with a large number of beams, representing the upper response time limit within the same RE series

The maximum value of 9ms must be adopted for safety distance calculation, typical values cannot be used

Total system stop reaction time after pairing with safety relay = 9ms (curtain) + safety relay actuation time

Model Selection Tips

If ultra-fast braking speed is required, select shorter protective height models from the same RE series; fewer beams deliver faster response speed.
