If the mounting distance between the transmitter and receiver is as follows, the optical axis
alignment is not necessary when mounting within the "parallel acceptable range" and "tilt
acceptable range".
• IG-010 : 3 to 500 mm
• IG-028 : 50 to 500 mm
If the distance is beyond the above ranges, align the optical axis after mounting.
