FAQ
Q1. What does “20M” indicate in this model?
It indicates a maximum sensing distance of up to 20 meters.
Q2. What is background suppression sensing?
It detects objects within a defined range and ignores background reflections beyond that distance.
Q3. Is detection affected by object color or surface finish?
No, BGS technology minimizes the effect of color and reflectivity.
Q4. Is this sensor NPN or PNP?
This model provides NPN open-collector output.
Q5. Is it suitable for harsh industrial environments?
Yes, with IP67 protection and a metal housing, it is suitable for demanding conditions.
