Fiber Fiber insertion mark After cutting the fibers using the Fiber Cutter (E9-F), place an insertion mark on the fiber so that it can be properly inserted into the Amplifier. Insert the fiber into the Amplifier up to this insertion mark. 2. Disconnection Be sure to press the lock button again to unlock before pulling out the fiber, otherwise the fiber may be deteriorated.. The fiber must be locked or released in a temperature range of C to 0 C.

Cutting Fiber Insert a fiber into the Fiber Cutter and determine the length of the fiber to be cut. Press down the Fiber Cutter in a single stroke to cut the fiber. An insertion mark can be placed on the fiber to serve as a reference when inserting the fiber into the Amplifier. Use the following procedure. Insert the fiber all the way into the cutter and confirm that you can see it in the hole at the back of the cutter, then press firmly down on the cutter. (2) Connection Do not pull or press the s. The s have a withstand force of 1 kgf (9.8 N) or kgf (29. N) max. (pay utmost attention because the fibers are thin). Do not bend the s beyond the permissible bending radius. Do not bend the edge of the s. Correct Amplifier Unit mm min. (1) Incorrect mm min. Insert the fiber into the Amplifier up to the insertion mark. Proper fiber performance will not be achieved unless the fiber is inserted all the way to the insertion mark. (This method is applicable to standard, 2.2-mm-diameter fibers only.) 12.6 2.2-dia. Insertion mark The cutting holes cannot be used twice. If the same hole is used twice, the cutting face of the fiber will be rough and the sensing distance will be reduced. Always use an unused hole. Use either one of the two holes on the right (refer to the following figure) to cut a thin fiber as follows: 1. An attachment is temporarily fitted to a thin fiber before shipment. Do not apply excess force on the s. Correct Incorrect Nylon wireholder Metal holder The Fiber Head could be break by excessive vibration. To prevent this, the following is effective: A one-turn loop can absorb vibrations. Tape Temporarily fitted 2.

Do not mount the back part onto the mounting bracket or the DIN track first and then mount the front part on the mounting bracket or the DIN track, or the mounting strength of the Amplifier Unit may decrease. Dismounting By pressing the Amplifier Unit in direction () and lifting the fiber insertion part in direction as shown in the following, the Amplifier can be dismounted with ease. () DIN track () (1) DIN track (2) In the case of side mounting, attach the mounting bracket on the Amplifier first, and secure the Amplifier with M screws and washers. The diameter of the washers should be 6 mm max. Washers (6 dia. max.) 8
Turning the Power On After the is turned on, the will be ready to operate in 0 ms maximum. If power is supplied to the and the load is connected to the independently, be sure to turn on the power supply connected to the first. Mutual Interference Protection Function Perform two-point teaching if two to three s are closely mounted together, at which time supply power only to the Unit in teaching operation in turn or block the emitters of the s not in teaching operation. EEPROM Writing Error Write errors may result at the time of teaching due to power failure or static noise, in which case the Unit beeps and the operation indicators flash. If any of these occur, re-input teaching using the teaching button on the Amplifier. Minute Sensing Object This datasheet shows typical examples for detecting minute objects. These typical examples are for reference use only, because these example operations were tested on Units sampled at random from a lot and the values described are average values. Do not assume that all Units ensure such operations. Others When the power is off: The moment power is turned off, the may output a pulse signal which could affect the operation of the devices connected to it. This will occur more often if power is supplied to the from an external power supply, thus affecting the connected timer and counter. Use a built-in power supply as much as possible to avoid this. In a case where the cord is extended, use a wire with 0. mm 2 min. The total length of the cord should be 0 m max. Power supply: If a standard switching regulator is used as a power supply, the frame ground (FG) terminal and the ground (G) terminal must be grounded, or otherwise the can malfunction influenced by the switching noise of the power supply. The supplied voltage must be within the rated voltage range. Unregulated full- or half-wave rectifiers must not be used as power supplies. Do not lay wiring to the Optical Sensor together with power lines in the same piping or ducts. Doing so will cause induction between the lines, possibly resulting in faulty operation or destruction. Always lay wiring to the Optical Sensor in separate or dedicated piping. Power line Attachment Units Applications E9-F Fiber Connector Use the following procedure (refer to the figure) to connect fibers via the Fiber Connector. Protective Spiral Tube Insert a fiber to the Protective Spiral Tube from the head connector side (screwed) of the tube. Retention unit Splice Retention unit Protective spiral tube Push the fiber into the Protective Spiral Tube. The tube should be straight so that the fiber is not twisted when inserted. Then turn the end cap of the spiral tube. Each should be as close as possible before they are connected. Sensing distance will be reduced by approximately % when fibers are connected. Only fibers with a 2.2-mm dia. can be connected. (Refer to page NO TAG for applicable s.) Protective spiral tube Secure the Protective Spiral Tube on a suitable place with the attached nut. Mounting panel Hexagon clamping nut Protective spiral tube Toothed washer 9
Use the attached saddle to secure the end cap of the Protective Spiral Tube. To secure the Protective Spiral Tube at a position other than the end cap, apply tape to the tube so that the portion becomes thicker in diameter.! WARNING The is not a safety component for ensuring the safety of people as defined in EC Directive 91/68/EEC, or as covered by separate European standards or by any other regulations or standards. Saddle Tube End cap Reflector Observe the Following Precautions when Using the Reflector (E9-R) Use detergent, etc., to remove any dust or oil from the surfaces where tape is applied. Adhesive tape will not be attached properly if oil or dust remains on the surface. The E9-R cannot be used in places where it is exposed to oil or chemicals. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
