Autonics BWP20-16P Area Sensor
Autonics BWP20-16P Through-Beam Area Sensor (20 mm Pitch, PNP Output)
Autonics BWP20-16P is a high-resolution through-beam area sensor with 16 optical axes and 20 mm pitch, designed for precise object detection across a wider sensing height in industrial automation.
The Autonics BWP20-16P is a through-beam area sensor engineered for high-resolution and wide-area detection using a 20 mm optical axis pitch. With 16 optical beams, it delivers an extended sensing height while maintaining excellent detection accuracy for small and closely spaced objects.
Featuring PNP open-collector output, IP65 protection, and advanced self-diagnostic and misalignment detection, the BWP20-16P ensures stable, long-term operation in demanding industrial environments.

FAQs
Q1. What is the benefit of 16 optical axes in BWP20-16P?
It provides a larger sensing height with high-resolution detection for small or closely spaced objects.
Q2. Is BWP20-16P suitable for personnel safety?
No. This product is not a safety light curtain.
Q3. What output does this model support?
PNP open-collector output.
Q4. Can multiple BWP20 sensors be installed close together?
Yes, using the MASTER/SLAVE interference prevention function.
Q5. Are M12 cables supplied with the sensor?
No. M12 connector cables are sold separately.
