Autonics BRQP400-DDTA Photoelectric Sensor
Autonics BRQP400-DDTA Background Suppression Photoelectric Sensor (400 mm, NPN, M18, IP67)
Short-range background suppression (BGS) photoelectric sensor with 400 mm fixed sensing distance and NPN open-collector output.
Delivers stable front-sensing detection independent of background distance, ideal for compact automation.
The Autonics BRQP400-DDTA is a background suppression (BGS) photoelectric sensor designed for precise front-sensing object detection at short distances while ignoring background surfaces. With a fixed 400 mm sensing range, NPN output, and IP67 protection, it is ideal for compact conveyors, packaging machines, and OEM automation systems requiring reliable detection.

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 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 color and reflectivity effects.
Q4. Is this sensor NPN or PNP?
This variant provides NPN open-collector output.
Q5. Is it suitable for industrial environments?
Yes. IP67 protection and metal housing make it suitable for harsh conditions.
