BGS/FGS Switchable Sensor
DLN Series Lineups
1. BGS/FGS switchable
BGS : Background suppression
- The sensor doesn't detect objects or background being out of the setting distance.
- This mode is suited for the detection of a target without background.
FGS: Background recognition: BGR (Foreground suppression)
- The sensor recognizes a background and detects a target by sensing the change in received light intensity.
- This mode is suitable for the detection of a target on a stable background.
2. Additional 25.4mm pitch mounting holes (Middle range models)
In addition to the conventional 29mm pitch holes, universal inch (25.4mm) pitch holes are equipped.
3. Wide selection of detection distance
Detection distance of 30mm, 40mm, 50mm and 100mm are available for Short range model, and 100mm, 150mm, 200mm and 300mm are available for Middle range model. Distance setting is not necessary when using the sensor at the specified distance.
4. Automatic interference prevention (Up to 2 sensors)
Prevents the mutual interference between adjacent two sensors by shifting the transmitting pulse automatically.
5. NPN/PNP dual output
The dual output enables inventory management more efficient. Model numbers followed by "P" are PNP models for which PNP output is allocated to the primary (black/ PIN 4) output.
Unique optical design realizes better performance and long detection distance with the compact housing (Short range models)

Detection of silicon wafers
Securely detecting silicon wafers even when water drops are on their surface.
Wafer carrier detection
Wafer carrier detected through view port of vacuum tank.
Electronic Component Mounting
Electronic component detection
Molded parts detected with background suppression photo sensor unaffected by color variation.
Detection of broken paper on rotary press
Convergent reflective sensor not affected by print colors.
Checking of parts assembly
The convergent reflective sensor detects objects to be assembled into small parts.
Checking of presence of CD
Reliable detection achieved without being affected by patterns printed on CD.
Checking for missing tile
Pallet checked for any missing tile. Reliable detection is achieved without being affected by tile color variation.
Background suppression photo sensor provides reliable detection and is unaffected by variation of bobbin color or shape.
Detection of lifting of ejected paper
Background suppression photo sensor is unaffected by color variation and therefore used for detecting any lifting of ejected paper.
Detection of absorption in lettuce wrapping
The limited range reflective sensor detects lettuce wrapping without being affected by color or shape of the detecting object.
Detection of steamed fish paste on belt conveyor
The limited range reflective sensor detects steamed fish paste without being affected by color, shape or material of the\ndetecting object.
Detection of objects in harsh environment
The limited range reflective sensor can detect material even in a harsh environment because it is not affected by dirt on lens or detecting objects.
Detection of coated plywood board
Plywood board of various colors detected with back ground suppression photo sensor.
