Reference: Preventing light interference of muting sensor
When a photoelectric sensor is used as a muting sensor, light interference may cause a muting error of
the F3SG-SR.
The cause and measures for light interference are shown as follows:
(1) Interference between muting sensors
• Use sensors with mutual interference prevention (such as retro-reflective E3Z-R

series)
• Use laser-type sensors (such as laser-type E3Z-LR

series)
• Take distance from a sensor causing the interference
• Displace beams for each other to prevent interference (change installation height or place them
crosswise)
• Install a physical barrier
• Attach interference prevention filter (provided for E3Z series as accessories)
• Attach a slit to reduce light intensity (provided for E3Z series as accessories)
• Lower the sensitivity
