FAQs
Q1. Is BW40-08P suitable for safety applications?
No. This is not a safety-rated light curtain.
Q2. What type of output does this model provide?
PNP open-collector output.
Q3. Can multiple BW40 sensors be installed close together?
Yes, using the MASTER/SLAVE interference prevention function.
Q4. What is the advantage of 40 mm pitch?
It is ideal for detecting larger objects over a wider area with fewer beams.
Q5. Are cables included with the sensor?
No. Connection cables are sold separately.
