Digital Fiber Amplifier E-DA-N The Ultimate Fiber Amplifier for Maximum Ease of Use and High Performance Be sure to read Safety Precautions on page 2. UL991* * UL certification including UL 991 testing and evaluation Applicable standards: UL 121-1 Additional application testing and evaluations standards: UL 991 and SEMI S2-2S Features Models with New Connector System Reduces Wiring, Saves Space, and Makes Maintenance Easier First in the Industry Patent Pending In Amplifiers with wire-saving connectors, the power supply is distributed to 1-conductor slave connectors through a - conductor master connector. This design has three major advantages. 1. Wiring time is significantly reduced. 2. Relay connectors are unnecessary, so wiring takes up less space and costs are reduced.. Storage and maintenance are simpler because it isn't necessary to distinguish between master connector and slave connectors on the Amplifier. Simplified Connector Design Up to 16 Amplifiers can be connected. Super Digital Display with Auto Power Control (APC) Circuit The passage of time causes the intensity of the 's lightemitting LED elements to deteriorate, which may make stable detection impossible. The E-DA-N is the first series of Fiber s to use an Auto Power Control (APC) circuit. This achieves strict detection by eliminating fluctuation in the digital value and is ideal for subtle detection such as stable detection of liquidcrystal glass.

E-DA-N Power Consumption Reduced by As Much As 7% Power consumption is reduced by as much as 7% from 18 mw to 6 mw (when the digital display is OFF). 18 mw 6 mw Digital Display Can Be Turned OFF or Dimmed during Eco-mode When the digital display is viewed infrequently during operation, current consumption can be reduced by dimming the display or turning it OFF entirely. (Eco-mode can be set from the Mobile Console only.) This eco-label is displayed on products that meet environmental standards established by OMR. Previous model E-DA-N (with digital display OFF) New Generation of Mobile Consoles the Size of Cellular Phones. Further Developing the Ultimate Power of Fiber Amplifiers. Remote Setting and Adjustment Perform settings, teaching, and fine adjustments at the end of the Fiber Unit. Previously, settings and teaching could be performed only on the Amplifier. Now, however, using a Mobile Console enables these operations at the end of the fiber. Strict adjustments can be made while checking the workpiece position. Display the light intensity and threshold at the same time. New Concept Patent Pending With group teaching, teach multiple amplifiers simultaneously. The tedious teaching that had to be performed separately for each Amplifier can now be performed for several Amplifiers at once using the Mobile Console. Eliminate inconsistency by using group zero reset. The group zero reset function can simultaneously reset the digital displays of multiple Amplifiers to. This function is useful to minimize variation between Amplifier values. Group teaching Function indicator section Channel setting section Light intensity monitor Threshold keys Flash the head and display the amplifier channels during operation. Even if the Amplifier and head are separated during operation, it is still possible to flash the head and display the amplifier channels.

Photoelectric s Technical Guide Design Power Reset Time Precautions for Correct Use The will be ready to detect within approximately 1 ms after the power is turned. If the and the load are connected to separate power supplies, turn the power before turning the load power. Any exceptions to this rule are indicated in Safety Precautions in individual product information. Turning OFF Power An output pulse may be generated when the power is turned OFF. It is recommended that the load or load line power be turned OFF before the power is turned OFF. Power Supply Types An unsmoothed full-wave or half-wave rectifying power supply cannot be used. Mutual Interference Mutual interference is a state where an output is unstable because the s are affected by light from the adjacent s. The following measures can be taken to avoid mutual interference. Countermeasure Use a with the interference prevention 1 function. 2 Concept Through-beam s Reflective s Install an inference prevention filter. Separate s to distance where interference does not occur. If s are mounted in close proximity, use s with the interference prevention function. 1 or fewer s: E-DA@-S, E-MDA, EC-LDA Fiber s Performance, however, will depend on conditions. Refer to pages E-DA-S/E-MDA and EC-LDA. 5 or fewer s: E-NA Fiber s 2 or fewer s: ET, EZ, EZM, EZM-C, ES-C, EG-L1/L, or ES-C Built-in Amplifier Photoelectric s (except Through-beam s) EC Photoelectric with separate amplifier A mutual interference prevention polarizing filter can be installed on only the EZ-TA to allow close-proximity --- mounting of up to 2 s. Mutual Interference Prevention Polarizing Filter: E9-E11 Check the parallel movement distance range in the catalog, verify the set distance between adjacent s, and install the s accordingly at a distance at least 1.5 times the parallel movement distance range. If the workpieces move from far to near, chattering may occur in the vicinity of the operating point. For this type of application, separate the s by at least 1.5 times the operating range. Workpiece 1.5 L Workpiece L Alternate Emitters and Receivers. Close mounting of s is possible by alternating the Emitters with the Receivers in a zigzag fashion (up to two s). However, if the workpieces are close to the Photoelectric s, light from the adjacent Emitter may be received and cause the to change to the incident light state. Emitter Workpiece --- Receiver Receiver 5 Offset the optical axes. Emitter If there is a possibility that light from another may enter the Receiver, change the position of the Emitter and Receiver, place a light barrier between the s, or take other measures to prevent the light from entering the Receiver. (Light may enter even if the s are separated by more than the sensing distance.) If s are mounted in opposite each other, slant the s as shown in the following diagram. (This is because the s may affect each other and cause output chattering even if separated by more than the sensing distance.) θ θ 6 Adjust the sensitivity. Lowering the sensitivity will generally help. http://www.ia.omron.com/ (c)copyright OMR Corporation 27 All Rights Reserved. C-2
Photoelectric s Technical Guide Noise Countermeasures for noise depend on the path of noise entry, frequency components, and wave heights. Typical measures are as given in the following table. Type of noise Common mode noise (inverter noise) Common noise applied between the mounting board and the +V and -V lines, respectively. Noise intrusion path and countermeasure Before countermeasure After countermeasure Noise enters from the noise source through the frame (metal). Mounting block (metal) +V V Inverter motor IM Noise (1) Ground the inverter motor (to 1 Ω or less) (2) Ground the noise source and the power supply (-V side) through a capacitor (film capacitor,.22 μf, 6 V). () Insert an insulator (plastic, rubber, etc.) between the and the mounting plate (metal). () Insert an insulator. Mounting block (metal) (2) +V Inverter motor V Noise Noise IM (1) Noise Radiant noise Ingress of high-frequency electromagnetic waves directly into, from power line, etc. Noise propagates through the air from the noise source and directly enters the. Noise source +V V Insert a shield (copper) plate between the and the noise source e.g., a switching power supply). Separate the noise source and the to a distance where noise does not affect operation. Noise source Shield plate (copper) +V V Power line noise Ingress of electromagnetic induction from high-voltage wires and switching noise from the switching power supply Noise enters from the power line. Noise Noise +V V Insert a capacitor (e.g., a film capacitor), noise filter (e.g., ferrite core or insulated transformer), or varistor in the power line. Insert a capacitor, etc. +V Noise V Wiring Cable Unless otherwise indicated, the maximum length of cable extension is 1 m using wire that is. mm 2 or greater. Exceptions are indicated in Safety Precautions in individual product information. Cable Tensile Strength When wiring the cable, do not subject the cable to a tension greater than that indicated in the following table. Cable diameter Tensile strength Less than mm N max. mm or greater 5 N max. Note: Do not subject a shielded cable or coaxial cable to tension. Repeated Bending Normally, the cable should not be bent repeatedly. (For bending-resistant cable, see Attachment to Moving Parts on page C-.) Separation from High Voltage (Wiring Method) Do not lay the cables for the together with high-voltage lines or power lines. Placing them in the same conduit or duct may cause damage or malfunction due to induction interference. As a general rule, wire the in a separate system, use an independent metal conduit, or use shielded cable. Power line Work Required for Unconnected Leads Unused leads for self-diagnosis outputs or other special functions should be cut and wrapped with insulating tape to prevent contact with other terminals. http://www.ia.omron.com/ (c)copyright OMR Corporation 27 All Rights Reserved.

Blue V Black OUT Brown +12 V 7 8 9 1 11 12 Mounting Attachment to Moving Parts To mount the Photoelectric to a moving part, such as a robot hand, consider using a s that uses a bending-resistant cable (robot cable). Although the bending repetition tolerance of a standard cable is approximately 1, times, robot cable has an excellent bending tolerance of approximately 5, times. Cable Bending Destruction Test (Tough Wire Breaking Test) With current flowing, bending is repeated to check the number of bends until the current stops.

Photoelectric s Technical Guide Securing Fibers The E Fiber Unit uses a one-touch locking mechanism. Use the following methods to attach and remove Fiber Units. (1) Attaching Fibers Open the protective cover, insert the fiber up to the insertion mark on the side of the Fiber Unit, and then lower the lock lever. Lock lever Fiber Fiber insertion mark Locked position 9mm Insertion position Lock released position Protective cover (2) Removing Fibers Open the protective cover, lift up the lock lever, and pull out the fibers. Adjustments Optical Axis Adjustment Move the Photoelectric both vertically and horizontally and set it in the center of the range in which the operation indicator is lit or not lit. For the ES-C, the optical axis and the mechanical axis are the same, so the optical axis can be easily adjusted by aligning the mechanical axis. Emitter Optical axis: The axis from the center of the lens to the center of the beam for the Emitter and the axis from the center of the lens to the center of the reception area for the Receiver. Mechanical axis: The axis perpendicular to the center of the lens. Emitter Receiver 1 2 Optical axis l Incident indicator or indicator OFF Optimum value Incident indicator or indicator OFF Optical axis Receiver Locked position Lock released position Protective cover Emission beam Mechanical axis Reception area Note:1.To maintain the fiber characteristics, make sure that the lock is released before removing the fibers. 2. Lock and unlock the fibers at an ambient temperature of 1 to C. http://www.ia.omron.com/ (c)copyright OMR Corporation 27 All Rights Reserved. C-5
