FAQ for E39-R7

When should I use large reflector vs small?
Large reflector (E39-R7) for: longer sensing distance, wider beam acceptance angle (easier alignment), dirty environments (more surface area). Small reflector for space-constrained installations.
What's the maximum sensing distance?
With E3Z-R sensor: up to 8m. With E3FA-R: up to 5m. With E3JK-R: up to 6m. Actual distance depends on sensor model and environmental conditions.
How do I align sensor and reflector?
Mount reflector perpendicular to sensor. Use sensor's operation LED: adjust until LED indicates stable detection. Large reflector has wider acceptance angle, making alignment easier.
Can I cut this reflector to size?
Yes, acrylic reflector can be cut with fine-tooth saw. Cut outside mounting holes. Seal cut edges with clear paint to prevent moisture ingress. Reflectivity reduced at cut edges.
