64 / 67 page  64 E39-F11 Sleeve Bender • The bending radius of the stainless steel tube should be as large as possible. The smaller the bending radius becomes, the shorter the sensing distance will be. • Insert the tip of the stain- less steel tube to the Sleeve Bender and bend the stainless steel tube slowly along the curve of the Sleeve Bender. Heat-resistant Fiber Units (E32-D51 and E32-T51) • The fibers of these Units cannot be extended using the E39- F10 Fiber Connector. • The maximum allowable temperature for continuous opera- tion with these Units is 130 °C. It is 150°C for short-term use. E32-T14 and E32-G14 These Units may enter the light-ON state if there are reflecting objects at the ends of the lenses. In this case, attach the black stickers provided to the ends of the lenses. Wafer Sensors (E32-L25(A)) • To ensure correct performance, insert the fiber with a white line into the emitter-side port of the Amplifier Unit. E32-T16 and E32-T16P To use the slit provided, peel off the backing sheet, align it with the edg- es of the sensing surface, and at- tach it to the sensing head. Use the slit in applications where saturation occurs (i.e., changes in light inten- sity cannot be obtained) due to short sensing distances. E32-M21 Separate the 4 fibers by distances sufficient to prevent inter- ference. Vacuum-resistant Fiber Units (E32-V) Although Flanges, Fiber Units on the vacuum side, and Lens Units have been cleaned, as an extra precaution, clean these products with alcohol before use in high-vacuum environ- ments to ensure that they are properly degreased. Liquid-level Detection Sensors (E32-D82F) • Secure the Fiber Unit using the unbendable section. Other- wise, the liquid-level detection position may be displaced. • For applications in hazardous environments, install the Fi- ber Unit in the hazardous environment but install the Ampli- fier Unit in a safe environment. Liquid-level Detection Sensors: Tube-mounting Models • Ensure that the tube is not deformed when using a band to secure the Fiber Unit. • Drops of water, bubbles, or haze inside the tube may cause malfunctions. E32-A07E1(E2) There is a difference in sensing object angle between E32-A07E1 and E32-A07E2. Select a model in accordance with the bending direction of a sensing object. Use the fiber with a model display tube as light emitting side. ● Adjustment E32-G14 When a Digital Fiber Amplifier is used, the sensing distance is short, making the incident light intensity large. This makes it impossible to teach without a workpiece. Liquid-level (E32-D82F) Detection Position The liquid-level detection po- sition is at a distance of 5.2 ±2 mm from the end of the fluororesin section. (Refer to the diagram on the right.) The liquid-level detection po- sition varies with the surface tension of the liquid and the degree of wetness at the Fiber Unit's detection position. ● Other Considerations Liquid Level (E32-D82F) • Operation may become unstable in the following cases: A Bubbles stick to the cone of the sensing head. B Solute is deposited on the cone of the sensing head. C The liquid has a high viscosity. • There are some liquids, such as milky white liquids, for which detection is not possible. • Do not let the end of the fluororesin section bump into an- other object. Damage to, or deformation of, the sensing head may result in unstable operation. Heat-resistant Fiber Units (E32-D81R(-S), E32-D61(-S), and E32-D73(-S)) The pitch of the emission-side and reception-side fiber-inser- tion ports varies with the Amplifier Unit. Be sure to use an ap- propriate Fiber Unit. Chemical-resistant Fiber and Liquid Level (E32-D82F) Fluororesin has high chemical resistance. However, applications in the atmosphere of vaporized chemicals (gases) or steam may cause malfunction or damage inside sensors. Run a full check before using in such environments. 1.2 mm dia. max.
