Autonics BRQM400-DDTA-P Background Suppression Photoelectric Sensor (400 mm, PNP, M18, IP67)
Short-range background suppression (BGS) photoelectric sensor with 400 mm fixed sensing distance and PNP open-collector output.
Provides stable detection independent of object color and background distance, ideal for compact automation.
The Autonics BRQM400-DDTA-P is a background suppression (BGS) photoelectric sensor designed for accurate object detection at short distances while ignoring background surfaces. With a fixed 400 mm sensing range, PNP output, and IP67 protection, it is ideal for conveyors, packaging machines, and compact OEM automation requiring consistent detection.

Instruction manual
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.
