- NEW MODELS
- Infrared light source type (D4IF-T/D4IF-TC4)
Adopts the 1450 nm wavelength that is easily absorbed by water (component)
Wide variety of infrared light source–related applications
■ Applications
-
Through-beam type Fiber-Optic Cables NF-TW01
Detection of chemicals in transparent bottles
Infrared LED light at 1450 nm, which is easily absorbed by water (component), allows detection of chemicals because the light is received when chemicals are not present and not received when chemicals block the optical axis.
-
Diffuse type Fiber-Optic Cables NF-DW01
Detection of adhesives
Infrared light with a wavelength of 1450 nm is easily absorbed by the water (component) in adhesives, so if adhesives is present, the light will be absorbed and the received light amount will decrease.
If no adhesives is present, the light will be reflected by the substrate, increasing the received light amount.
■ Recommended applications
-
Silicon solar panel overlap detection
The moderate penetration of 1450 nm wavelength infrared light with silicon solar panels makes it possible to detect overlaps based on the difference in received light amount of one wafer compared with twowafers.
-
Pick-and-press laminated film overlap detection
Because 1450 nm infrared light is easily absorbed by films, the difference in the received light amount can be used to distinguish between one or two sheets even if the film is transparent.

- Short-range/High accuracy type
(D4RF-TD-Y/D4RF-TA-Y/D4RF-TDM-Y/D4RF-TDS-Y)
■ Detects small objects in a clean environment
■ Detects minute changes in light intensity
-
● Detection of small objects with only minute changes
in light intensity
-
● Short-range detection of small objects
■ Applications
-
Passing detection of electronics components
Sufficient light intensity ensures stable detection of passing objects.
-
Counting the number of dropped screws/small objects
Sufficient light intensity ensures stable detection of passing objects.
-
Detecting edge of film alignment
The intensity of light is enough to detect film edges.
- NEW MODELS
- Analog output model (D4RF-TA/D4RF-TA-Y)
Selectable according to your analog devices
● Current output: 4 to 20 mA ● Voltage output: 0 to 10 V or 1 to 5 V
-
■ Applications
Detection of film meandering
Fiber-Optic Sensors with analog output can feedback the position of the edge by analog output.
Screen Fiber-Optic Cables NF-TS40 can be utilized for alignment control.
It has 40 mm width screen beam and in that area the sensor can detect edge of the film. -
■ Useful functions
Manual adjustment of the analog output range
The analog output range set with the teach function can be changed manually.
【Setting examples】
When the received light amount is within the analog output range (200 to 800), a current of 4 to 20 mA is output.
Display the setting analog output values
(4 mA → 200、20 mA → 800)
