FAQs
Q1. Is BW40-16P a safety light curtain?
No. This product is not a safety sensor and should not be used for personnel protection.
Q2. What is the advantage of 40 mm pitch?
It is suitable for detecting larger objects while covering a wider area with fewer beams.
Q3. Can multiple BW sensors be installed side by side?
Yes, using the MASTER/SLAVE interference prevention function.
Q4. What output does this model support?
PNP open-collector output.
Q5. Is the cable included?
No, M12 connector cables are sold separately.
