Frequently asked questions
What laser safety class does the sensor belong to?
The sensor uses a Class 2 laser (output power < 1 mW), which is generally safe for the eye but direct staring should be avoided.
How should the sensor be cleaned?
Wipe the sensor with a soft, slightly damp cotton cloth; do not use corrosive or volatile cleaning agents.
Can the sensor be immersed in water?
No, the sensor must not be immersed in water even though some models have an IP67 rating.
