DLN Series (Infrared LED type)
BGS/FGS Switchable Sensor
Versatile BGS/FGS sensor with an Infrared LED light source
- For specific applications
where an invisible light spot is preferable, such as automatic faucets or gaming machines. - For specific materials
that absorb visible red light. - BGS/FGS selectable
BGS: Background suppression
FGS: Background recognition (BGR) - NPN/PNP dual output
for more efficient inventory management.

Feature
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.
Detection principle
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.
Detection principle
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)

Printing
Detection of broken paper on rotary press
Convergent reflective sensor not affected by print colors.
Automatic assembly
Checking of parts assembly
The convergent reflective sensor detects objects to be assembled into small parts.
Consumer electronics/OA
Checking of presence of CD
Reliable detection achieved without being affected by patterns printed on CD.
Steel/Ceramic
Checking for missing tile
Pallet checked for any missing tile. Reliable detection is achieved without being affected by tile color variation.
Textile
Bobbin detection
Background suppression photo sensor provides reliable detection and is unaffected by variation of bobbin color or shape.
Printing
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.
Printing
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.
Printing
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.
etc.
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.
etc.
