Autonics BRQM400-DDTA Background Suppression Photoelectric Sensor (400 mm, NPN, M18, IP67)
Compact background suppression (BGS) photoelectric sensor with 400 mm sensing distance and NPN open-collector output.
Ensures reliable detection independent of object color or background distance, ideal for precision automation.
The Autonics BRQM400-DDTA is a background suppression (BGS) photoelectric sensor designed for accurate object detection at short to medium distances while ignoring background surfaces. With a fixed 400 mm sensing range, NPN output, and IP67 protection, it is ideal for conveyors, packaging machines, and compact OEM automation where detection accuracy is critical.

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 set distance and ignores backgrounds beyond that range.
Q3. Is detection affected by object color or reflectivity?
No, BGS technology minimizes color and reflectivity influence.
Q4. Is this NPN or PNP?
This model provides NPN open-collector output.
Q5. Is it suitable for harsh industrial environments?
Yes, IP67 protection and metal housing make it suitable for demanding conditions.
