FAQ
Q1. What does “400” indicate in this model?
It indicates a fixed sensing distance of 400 mm.
Q2. What is background suppression sensing?
It detects objects at a defined distance and ignores backgrounds beyond that range.
Q3. Is detection affected by object color or surface finish?
No. BGS technology minimizes color and reflectivity effects.
Q4. Is this NPN or PNP output?
This variant provides PNP open-collector output.
Q5. Is it suitable for harsh industrial environments?
Yes. IP67 protection and metal housing make it suitable for demanding conditions.
