1 FS0 High Accuracy Fibreoptic Functions From ultra-high precision to ultra-high power: A single unit covers every application The FS-V Series offers three levels of detection to suit the application. Model: FU- 0 mm Mode 00 mm Mode 00 mm Mode The FS-V Series can be used for high-precision detection of wire as thin as 0.0 mm in diameter with a thrubeam type fibre unit. It can also be used for detection in harsh environments where oil or dust eists. Because the FS-V Series can work in almost all applications, sensor selection is easy. Detection with ultra-high precision Detection under harsh environment Readable digital display of moving target: Peak/bottom hold display The digital LED monitor can hold the displayed value. The light intensity value of a moving target can be frozen to control the numerical values easily. The received light intensity At a glance digital LED monitors interrupted light The digital LED monitor displays the light quantity at the light-receiving element incrementally from 0 to 09. This enables you to determine the degree of dust accumulation on the sensor and the deviation in the optical ais. In addition, checking the change in the light quantity with the digital reading ensures an optimal setting value, improving the detection reliability.

2 FS0 High Accuracy Fibreoptic ToughFle Fibre Principle Keyence has developed the toughest fibre unit series by bundling multiple s of µm diameter. These fibres will work normally without any malfunction even when they are bent to a minimum radius or when they are hit or pulled suddenly. Keyence has also maintained a long detecting distance while using this unique design. Including focused small spot model, area detection model, ultra-long detecting distance model, and thin sleeve models, every application can be improved with maintenance efficiency. Plus, the latest armoured model is sheathed by a fleible jacket to protect the fibre from daily wear and eposure to harsh environmental conditions. Conventional fibre ToughFle will not break even when sharply bent. More fleible than conventional spiral fibres. ToughFle will not break even when sharply bent. FU-7G/77G Fibre A standard fibre will easily break. ToughFle fibre A single- eposed to ecessive bending will easily break. ToughFle will not break even when sharply bent. The 7- is hardly affected by ecessive bending. ToughFle Fibre Features Tough even when entangled Even if the fibre unit becomes entangled, the fibre unit and the base of the head will continue to perform. Shock-resistant The fibre unit and the base of the head will continue to perform even when dropped or struck by a tool. Ready for immediate use Armoured ToughFle provides a cost and labour savings by eliminating the need for protective tubing.

3 High Accuracy Fibreoptic FS0 Fibre Unit Selection Guide (major models only) Break-free ToughFle Fibres [Patent pending]: FU-7/77/FZ/FZ/FZ/Z/Z/ Fibres with a minimum bend radius of mm retain light intensity even when folded. These innovative fibres can be routed just like an electric wire, enabling installation anywhere. Compact Definite Reflective Fibres: FU-/V/R These fibres are ecellent for detection in tight spaces such as being embedded in a robot arm or on a conveyor. Detection is almost unaffected by target backgrounds. Wafer Mapping Fibre: FU- The FU- incorporates a special lens and prism and has an aperture angle of enabling ultra-narrow beam emission. This capability is well suited to mapping (positioning) wafers placed at a small pitch. Liquid Level Detection Fibre: FU-9 The FU-9 is totally encased in a Teflon -sheath. It is liquid resistant and can be used to reliably detect a liquid surface level. Tube-mountable Liquid Level Detection Fibre: FU-9 The FU-9 is a liquid-level-detection fibre that can be easily mounted to a tube. Because it is lightweight it can be mounted in anywhere. High-fle Fibres: FU-//9/9///9/7/79 These fibres, which provide higher fleibility than an electric wire, can endure repeated bends. The bend radius of mm makes fibre routing easier and saves mounting space. Area Detection Fibre: FU- The FU-, which provides a detecting area mm wide, is suitable for detecting vibrating targets or minute targets. A target as small as. mm in diameter can be accurately detected. Long Detecting Distance, Side-view Fibre: FU- The FU- provides a long detecting distance of.7 m and an aperture angle of, enabling narrow beam emission. Almost no light reflected by surrounding objects enters the receiver, enabling stable detection. Focused Beam Lens and Fibre: FU- + F-HA The FU- with the F-HA forms a tiny beam spot 0. mm in diameter at a detecting distance of 7 mm. This combination is very useful for detecting minute targets or positioning with high accuracy. Narrow-beam Fibre: FU- The light diffusion angle is (/ of conventional models), allowing narrow beam emission. This capability is ideal for detecting minute targets.
