Fiber optic sensors and fiber optics - limitless and customized

• Ø 1.5 mm thin cylindrical or 2 mm ultra-flat fiber optics with lateral light emission for integration into a wafer handler
• Highly repeatable detection and positioning of 0.1 mm thin wafer
• Low jitter of 12 µs with a 50 µs response time for maximum process speed

• Graphical and interactive parameterization of fiber optic sensors via Baumer Sensor Suite
• Fast format changes via IO-Link dual channel
• Fiber optics with 90° rotated fiber output for easy, space-saving installation
• Fiber optics with an integrated lens have a smaller beam angle which leads to an increased range 

• Array fiber optics with linear fiber arrangement are ideal for area detection from 1300 mm in the x-direction to 100 mm in the y-direction
• Position-independent, orientation-independent, and object-independent detection of moving objects
• Ejection control with presence detection or counting of pills, screws, and other irregular objects is a typical example 

• Resistant to mechanical, chemical, and thermal impacts in industrial environments
• Fiber optics with metal sheathing (armored) for applications with high mechanical stress
• Glass fiber optics for use in ambient temperatures from -60 °C to +250 °C 

• Reliable detection of transparent media - with direct contact and contactless through a hose
• Reliable detection of fill level and leakage even with hazardous liquids
• Light guide with PTFE sheath for protection against aggressive media

For the installation in tight spaces fiber optics with 90° angled fiber outlet or cylindrical and square fiber optics with lateral light emission (side view) are especially suitable. This also reduces the risk of unintentional cable damage caused by a tool.

Fiber optics have an aperture angle of approx. 60°. The light is bundled with the aid of add-on lenses or fiber optics with integrated lenses. This has the advantage that the aperture angle can be reduced as well as unwanted stray light. The detection range can be extended. In addition, the focus distance and the beam diameter can be changed with different add-on lenses.

Highly flexible fiber optics have the advantage that signal quality can be guaranteed regardless of smallest bending radii. A distinction must be made as to whether the fiber optics is subject to a static bending radius or a dynamic bending radius. 

Array fiber optics are used for position-independent detection of irregular objects. Unlike fiber optics with a single, point-shaped light beam, array fiber optics generate a broad, linear light band. Depending on the width of the array fiber optics and the operating principle, the maximum detection area can be adjusted in both the x and y directions. Array fiber optics with an integrated lens feature a small opening angle of 3°. This results in a parallel, homogeneous light band, an even distribution of light intensity and an extended range.

Fiber optics are characterized by their high chemical, mechanical and thermal resistance. The different material properties of glass and plastic fiber optics are essential. Glass fiber optics have a very high resistance to chemicals such as acids and solvents. To increase the mechanical resistance, the fiber optics are enclosed with an additional metal protective sleeve to reduce the risk of mechanical damage.
