Rockwell Automation 440N SensaGuard 18 mm Plastic Barrel Unique Coded Installation Instructions - Manual (Page 5)

Minimum Distance Between Sensors
Misalignment Curve
18 mm Unit with 18 mm Target 18 mm Unit with 30 mm Target
Note: There must be a minimum spacing of 4 mm
(0.157 in) if actuator and sensor face approaches
laterally. This will prevent false triggering due to the
side lobe areas.
