OMRON’s Fiber Sensors continue to support an increasing range of applications.
Standard configuration. These Fiber Units are mounted into a hole drilled in a bracket and secured with nuts.
The Right-angle Model prevents snagging on the cable because the cable runs along the mounting surface.
Inserted where space is limited. (Secured using a set screw.)
Ultramate space-saving by micro-fiber head. (1 dia. 10 mm)
Thin profile for mounting in limited spaces.
Mounts directly without using special mounting brackets.
Sleeve Models (Close-range Detection)
Sleeve Fiber Units allow detection away from the point of installation for stable close-range detection of small objects.
The shape of sleeve can be changed freely.
Small-Spot, Reflective (Minute Object Detection)
Select the Fiber Unit that is best suited for the workpiece size and installation distance.
(Refer to Reference Information for Model Selection)
Available with a variable-spot Lens Unit to change the spot diameter without replacing the fiber. The spot diameter can
be adjusted according to the size of the workpiece by changing the withdrew length and sensing distance.
Refer to the following graph, which shows the relation between the withdrew length, focal distance, and spot diameter.
* Withdrew length: Approx. 1.3 to 5.8 mm
High-power Beam (Long-distance Installation, Dust-resistant)
Suitable for detection of large objects and for use in large-scale installations.
Powerful enough to resist the influences of dust and dirt.
In addition to the products listed on this page, Lenses are available to extend the sensing distance.
Narrow View (Detection Across clearance)
The fine beam prevents false detection of light that is reflected off surrounding objects.
Detection without Background Interference
point are not detected.
They are not easily affected by the material or color of the sensing object.
Transparent Object Detection
The light beam passes through the object twice, this model interrupts light more than Through-beam model.
The specially designed filter eliminates undesirable light, which allows significantly more light to be interrupted for
stable detection of films.
Limited-reflective (Glass Detection)
intersect at the same angle.
This allows for stable detection of glass because the Fiber Units receives the specular reflection of the glass when the
glass is in the sensing range.
These Fiber Units are made from fluororesin for resistance to chemicals.
Chemical-resistant Data for Fluororesin (Reference)
Note: Results depend on concentration.
Capable of withstanding one million repeated bends.
snagging or shock.
Select the model according to heat-resistant temperature.
Area Beam (Area Detection)
for meander detection, or for detecting workpieces with holes.
Detect the liquid level inside transparent tubes. Strap the Fiber Unit to a tube with band.
Detect the liquid level by direct contact with the liquid.
This model has excellent chemical-resistance because the Fiber Unit is covered in fluororesin.
Can be used under high vacuums of up to 10-5Pa.
Available in models with heat resistant up to 120 or 200C.
Configuration Example for using under vacuum
FPD, Semiconductors, and Solar Cells (Limited-reflective)
No variation in detection positions even if the sensing distance changes.
・Tilting workpiece does not affect detection.
Stable detection is possible even for difficult-to-detect curved surfaces.
Glass Presence Detection in Wet Processes
・The spherical heads ensure stable detection without being influenced by liquid.
FPD, Semiconductors, and Solar Cells (Through-beam)
・Easy to adjust optical axis.
(Typical alignment error between mechanical and optical axes is only 0.1.)
・Reliably wafer detection, even when stacked closely together.
