Triple beam sensor
|
|
The MQ-W subminiature sensors with their integrated amplifier work on optical triangulation principles. This ensures reliable detection regardless of object colour or surface condition. Even with a partially soiled lens, the sensor guarantees detection. Sealed according to IP67, the sensors are made to withstand adverse ambient conditions. Characteristics: - Utilises optical triangulation
- Distance control allows background suppression
- Independent of object colour and surface condition
- Resistant against vibration and shock
