Installation guidelines
For best performance of the O1D family of photoelectric sensors, please adhere to the installation guidelines.
Should you need additional support, feel free to contact our service center at 888-704-0702 and speak to one of our applications engineers.
The O1D sensors have three zones to keep in mind as shown in the image below. Different part numbers within the family will have different specifications for these zones. Please refer to individual datasheets for details.
- Blind zone – because of the time of flight technology, a minimum distance between the sensor face and target is required for accurate detection. If an object is detected within this zone, “near” will be shown on the sensor display.
- Measuring zone – the distance where target detection is guaranteed at the accuracy specified on the datasheet. Note accuracy can vary by target color and distance as shown on the datasheet.
- Background suppression zone – the distance beyond the measuring zone where reflections from objects are ignored by the sensor. The operating instructions refer to this zone as the “unambiguity range”.
1 = Blind zone; 2 = Measuring zone; 3 = Background suppression zone
The pmd technology used in the O1D distance sensors is very forgiving in mounting angle as seen below in the video. The video shows the OGD sensor, but the technology is the same.
The unit is supplied without mounting accessories, but the following table shows the most popular accessories. Additional accessories can be found with the product datasheet.
Level detection with O1D300
O1D300 can be used for level detection of bulk solids and opaque, non-shiny liquids in a tank or bin. The measuring principle, conditions and the accessories needed are very similar to other O1D sensors. It’s programming menu is structured specifically for level applications.
Install the unit so that the medium to be detected is within the measuring range (O1D300: 0.2…10m). Mount the sensor in a way that a distance (D) of min. 20 cm remains between the highest possible level and the front lens of the sensor. The maximum measuring distance (H) between the front lens of the sensor and the tank bottom or the programmed level is 10 m. A reference height at a longer distance cannot be set. Refer to the operating instructions for details.
