Sensor
EDR-02 Infrared Sensor
EDR-02 is an infrared edge sensor for optical web edge detection in closed-loop web guiding systems. It is suitable for opaque or contrast-friendly web materials where light-based edge sensing can provide stable feedback.
Key Features
Infrared edge detection for clear and stable web edge conditions.
- High detection accuracy for stable web edge feedback
- Fast response for closed-loop guiding correction
- Strong anti-interference design for practical production environments
- Anti-light interference design for common factory lighting conditions
- Custom opening sizes can be selected according to the application

Replacement & Spare Part
Replacing an EDR-02 on an existing machine?
EDR-02 is an EURDOW sensor and works only with EURDOW controllers — the WGC01 and WFC01, or the discontinued WGC02. It runs on 24 V and gives a digital signal output.
What to send us
A photo of the sensor model marking, a photo of it in place showing the cable and mounting bracket, the controller model it is connected to, and the quantity.
What ships
The sensor. Cable and mounting bracket can be supplied as well if yours are damaged — say so in your message.
Dimension drawing: available on request. Ask for it by email and check it against the unit on your machine before ordering.
Similar-looking sensors that are not interchangeable
Fork-shaped edge sensors from different systems look alike on the machine. The supply voltage, the output signal and the controller they talk to are what decide whether one can replace another.

| Supply | 24 V | 24 V | 12 V DC |
| Output | Digital signal | — | 0–5 V analog + 2 × NPN |
| Detection range | 7 mm | 7 mm | 11 mm |

| Controllers | WGC01 / WFC01 / WGC02 | WGC01 / WFC01 / WGC02 | PC100A |
An ES201 cannot replace an EDR-02, even though both are infrared edge sensors: different supply, different signal, different controller. Within the EURDOW system, EDR-02 and EDS-02 share the same controllers — choose between them by material, infrared for opaque webs and ultrasonic for transparent ones.
Commonly reported EDR-02 symptoms
Not every fault that looks like a failed sensor is one. These are the patterns we are asked about most often, and what they usually turn out to mean.
No signal at all
Check the 24 V supply and the cable first. A cable damaged where it flexes is more common than a failed sensor.
Unstable on clear or very glossy film
Infrared needs an edge it can see. On transparent or mirror-like webs this is a material limitation, not a fault — the EDS-02 ultrasonic sensor is the usual answer.
Reading changes with the lighting
EDR-02 is rated for 10,000 lux sunlight and 3,000 lux fluorescent light. Direct sun through a window or a lamp aimed into the opening can exceed that; shade the sensor before replacing it.
A replacement sensor does not work
Check that it is actually an EDR-02 or EDS-02. A sensor from another system, such as an ES201, will not work with an EURDOW controller.
If the symptom is not on this list, describe it in your message. It is cheaper for both of us to identify the actual fault than to ship the wrong part.
Selection Notes
Choose the sensor around the material edge.
EDR-02 is a practical choice where the web edge can be detected optically. If the web is transparent or very low contrast, EDS-02 ultrasonic sensing may be the safer recommendation.
Good Fit
Opaque or contrast-friendly materials with stable edge conditions.
Check First
Transparent, highly reflective or unstable edge materials should be reviewed before selection.
System Match
Works only with EURDOW controllers (WGC01, WFC01 or legacy WGC02), together with an EURDOW actuator and a correction frame selected for the machine section.

Read ArticleFAQ
When is EDR02 a suitable sensor?
EDR02 is suitable when the material is opaque or has a clear edge that infrared sensing can detect reliably in the planned installation position.
When should ultrasonic or CCD sensing be reviewed instead?
Use ultrasonic sensing for transparent or low-contrast webs, and review CCD sensing when the guide must follow printed lines, marks or color edges.
What installation details affect infrared sensing?
Opening size, sensor alignment, material edge stability, ambient light, dust, web flutter and mounting distance can all affect infrared edge detection.
What RFQ details should be sent for EDR02?
Send material type, opacity, web width, line speed, machine section, expected edge movement, installation photos and available sensor mounting space.
