1. Easy-to-read OLED display
In addition to clear and detailed detection status and values displayed on the OLED display, the setting menu can be displayed in English, Japanese, Korean, Simplified Chinese or Spanish.
Stretch display mode of received light amount
Displayed values of threshold and received light amounts can be set to be multiplied by 10 or 50 for easier perception.
2. Fiber insertion indicators to check insertion depth of Fiber-Optic Cables
The correct insertion status can be confirmed at a glance.
3. Large LED indicators
Three-dimensional indicators provide operators with superb visibility of sensor status from a distance.
4. Larger buttons for secure operation
Larger buttons with the tilted top shape help operators easy setting of parameters.
5. Cover with wide opening angle
The cover opens up 180°, keeping it out of the way of the buttons.
In addition, the display is clearly visible because the cover hides only the buttons.

Easy teaching
Hold display
Amounts of received light can be set to display at peak/bottom values.
This makes you easier to grasp exact values of detection to adjust a threshold with correct operation margin.
Batch setting to connect Fiber-Optic Sensors
Batch setting to connected Fiber-Optic Sensors.
Settings such as "Copy to all", "Zeroing all" and "All teach" are copied from the main unit to the expansion units as a batch.
Max. 15 units of Fiber-Optic Sensors can be connected.
Enhanced detection in a long distance
High-power LEDs combined with a lens designed for high efficiency increased the sensing distance.
This ensures detection that is stable and resistant to dust and contamination.
Ultra-fast response time
Response time can be selected from 6 speed modes, as fast as 16 μs.
This facilitates 30,000 or more objects to be detected in 1 second.
Adopts the 1,450 nm wavelength that is easily absorbed by water (component)
Wide variety of infrared light source–related applications
Applications
-
Detection of Chemicals in Transparent Bottles
Infrared LED light at 1,450 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.
-
Detection of Adhesives
Infrared light with a wavelength of 1,450 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. -
Silicon Solar Panel Overlap Detection
The moderate penetration of 1,450 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 1,450 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-T-Y/ 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.
Selectable according to your analog devices
- Current output: 4 to 20 mA
- Voltage output: 0 to 10 V or 1 to 5 V
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)
Application
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.
Select when using interconnection type for IO-Link or when using the interference prevention function.
Connect to PLC or IPC via communication unit
The lineup includes communication units with various interconnection types to meet diverse customer needs - for example, eliminating the display or operation keys by allowing settings and monitoring by PLC or IPC, or reducing cables.
- Max. 16 units of Fiber-Optic Sensors can be connected.
- Communication of output and identification.
- Reduced wiring : Simply connect to gateway. Cable-less models are also available.
(When interconnecting four or more Fiber-Optic Sensors, supply power not only to the UC2-IOL but also to the
Fiber-Optic Sensors main unit on the left end.) - Low cost and low current consumption : Models without OLED displays are also available.
When connecting more than four Fiber-Optic Sensors to IO-Link Gateway UC2-IOL, additional 24 VDC power must be supplied to the terminal Fiber-Optic Sensor.
The 0 V of the supply power should be connected to the 0 V of the power supplied to IO-Link Master to match the potential.
If there are three or less Fiber-Optic Sensors, additional power is not required.
Connectable communication unit
By connecting D4RF to UC2-IOL, connected models that cannot communicate via IO-Link can be connected to IO-Link Master.
- Use UC2 with firmware version 2.1.0R or later (from lot 2307 or later).
By connecting D4RF to UC1-EC, it can communicate with PLC via EtherCAT.
- Use UC1 with firmware version 1.1.0 or later.
By connecting D4RF to UC1-EP, it can communicate with PLC via EtherNet/IP.
- Use UC1 with firmware version 1.2.0 or later.
