Autonics BRQM3M-PDTA-P Photoelectric Sensor
Autonics BRQM3M-PDTA-P Background Suppression Photoelectric Sensor (3 m, PNP, M18, IP67)
Medium-range background suppression (BGS) photoelectric sensor with up to 3 m sensing distance and PNP open-collector output.
Provides accurate detection independent of object color and background distance, ideal for precision automation.
The Autonics BRQM3M-PDTA-P is a background suppression (BGS) photoelectric sensor designed for stable and precise object detection at medium distances while ignoring background surfaces. With up to 3 m sensing range, PNP output, and IP67 protection, it is ideal for conveyors, packaging machines, and OEM automation systems where consistent detection is critical.

FAQ
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 detection affected by object color or surface finish?
No, BGS technology minimizes the effect of color and reflectivity.
Q4. Is this model NPN or PNP?
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.
