Các linh kiện cảm biến của OMRON thực hiện việc phát hiện, đo lường, phân tích và xử lý những thay đổi khác nhau diễn ra tại các địa điểm sản xuất, chẳng hạn như thay đổi về vị trí, chiều dài, chiều cao, độ dịch chuyển và hình dạng bên ngoài. Chúng cũng góp phần vào việc dự đoán và ngăn ngừa các sự kiện có thể xảy ra trong tương lai.
Với các loại cảm biến có bộ khuếch đại tách rời này, ánh sáng từ bộ khuếch đại được truyền qua sợi quang, cho phép thực hiện việc phát hiện tại những không gian hẹp hoặc các vị trí khó tiếp cận khác.
Các bộ cảm biến sợi quang (Fiber Units) với đa dạng hình dạng, khả năng chống chịu môi trường và các loại chùm tia đặc biệt, có thể đáp ứng các yêu cầu của bạn khi kết hợp cùng các bộ khuếch đại (Amplifier Units).
Standard Installation
Threaded Models
Hex-shaped Models
• You can easily mount these Fiber Units by making a hole in the bracket and tightening just one nut.
• The cable follows the wall, so extra space is not required, and the cable will not get caught on other objects.
A Fiber Unit with Build-in Lens is the new standard in fiber units. We recommend this new standard Fiber Unit that achieves stable detection with a high-power beam.
You don’ t have to worry about the lens falling off and getting lost. Through-beam Flat Fiber Units are also available.
Cylindrical Models
• Inserted where space is limited. (Secured using a set screw.)
• Ultramate space-saving by micro-fiber head. (1 dia. × 10 mm)
Saving Space
Flat Models
• 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.
Beam Improvements
Small-Spot, Reflective (Minute Object Detection)
• Small-spot is ideal for detecting minute objects.
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.

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)
• Maximum sensing distance without attaching a Lens: 20 m (E32-T17L)
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.

• 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
• These Fiber Units detect only objects in the sensing range. Objects in the background that are located beyond a certain
point are not detected.
They are not easily affected by the material or color of the sensing object.
point are not detected.
They are not easily affected by the material or color of the sensing object.
Transparent Object Detection
Retro-reflective
• Retro-reflective Fiber Units are ideal for detecting transparent objects.
The light beam passes through the object twice, this model interrupts light more than Through-beam model.
The light beam passes through the object twice, this model interrupts light more than Through-beam model.
• Excellent detection performance with transparent films. (E32-C31 2M + E39-F3R)
The specially designed filter eliminates undesirable light, which allows significantly more light to be interrupted for
stable detection of films.

stable detection of films.
Limited-reflective (Glass Detection)
• These Fiber Units are based on a limited-reflective optical system where the emitting light and receiving light axes
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.

Environmental Immunity
Chemical-resistant, Oil-resistant
• These Fiber Units are made from fluororesin for resistance to chemicals.
Chemical-resistant Data for Fluororesin (Reference)
Note: Results depend on concentration.
Bending-resistant, Disconnection-resistant
• Capable of withstanding one million repeated bends.
• A large number of independent fine fibers ensures good flexibility. Suitable for use on moving parts without easily
breaking.

• Protective Stainless Spiral Tube is available for covering the fiber cable to protect it from accidental breaking due to
snagging or shock.

Heat-resistant
• Wide product variety for temperatures from 100 to 350°C.
Select the model according to heat-resistant temperature.

Special Applications
Area Beam (Area Detection)
• Area beams are optimum for detecting workpieces presented in inconsistent positions, such as falling workpieces, or
for meander detection, or for detecting workpieces with holes.
for meander detection, or for detecting workpieces with holes.
• This Fiber Unit is ideal for meander detectin because it outputs the digital value in a linear relation to the interrupted
light distance.
light distance.
Liquid-level Detection
• Fiber Units for detecting liquid levels are available in two types: for tube mounting and liquid contact.
Tube-mounting Types
Detect the liquid level inside transparent tubes. Strap the Fiber Unit to a tube with band.
Liquid-contact Type
Detect the liquid level by direct contact with the liquid.
This model has excellent chemical-resistance because the Fiber Unit is covered in fluororesin.
Vacuum-resistant
• Can be used under high vacuums of up to 10-5 Pa.
• Available in models with heat resistant up to 120 or 200°C.
Configuration Example for using under vacuum
