Instruction manual
Q1. What does “3M” indicate in this model?
It indicates a maximum sensing distance of up to 3 meters.
Q2. What is background suppression sensing?
It detects objects within a defined range and ignores background reflections beyond that distance.
Q3. Is this sensor affected by object color or reflectivity?
No, BGS technology minimizes color and reflectivity effects.
Q4. Is this model NPN or PNP?
This variant provides PNP 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.
