Frequently Asked Questions (FAQs)

Q1: What does the 20 mm blind zone mean?
It is the minimum distance at which the sensor cannot detect objects. This short blind zone is ideal for close-range tasks.

Q2: Can it be used outdoors?
Yes, the IP67 housing allows for outdoor usage with protection against water, dust, and humidity. However, avoid direct sunlight or extreme heat.

Q3: What is the Teach-in function?
The white wire (WH) can be briefly connected to GND to set a custom detection point. This allows field calibration for your specific application.

Q4: What makes this sensor suitable for fast-moving objects?
Its 50 ms response time and high switching frequency ensure accurate, real-time detection in fast-paced environments.
