WARNING These Sensors cannot be used in safety devices for presses or other safety devices used to protect human life. These Sensors are designed for use in applications for sensing workpieces and workers that do not affect safety. Precautions for Safe Use To ensure safety, always observe the following precautions. Wiring Item Typical examples Power Supply Voltage Do not use a voltage in excess of the operating voltage range. Applying a voltage in excess of the operating voltage range, or applying AC power (100 VAC or greater) to a DC Sensor may cause explosion or burning. Load Short-circuiting Do not short-circuit the load. Doing so may cause explosion or burning. * DC Three-wire NPN Output Sensors Load Brown Sensor --- Black Blue * DC Three-wire NPN Output Sensor Load Brown Sensor * AC Two-wire Sensors Example: E3E2 (Load short circuit) Black Blue + - Brown Load (Load short circuit) Sensor Blue Incorrect Wiring Do not reverse the power supply polarity or otherwise wire incorrectly. Doing so may cause explosion or burning. * DC Three-wire NPN Output Sensors Example: Incorrect Polarity * DC Three-wire NPN Output Sensors Example: Incorrect Polarity Wiring Load Brown Sensor Load Black + Blue Load Brown Brown Sensor Black Blue Sensor - Blue + - Black + Connection without a load If the power supply is connected directly without a load, the internal elements may burst or burn. Be sure to insert a load when connecting the power supply. * DC Three-wire NPN Output Sensors Brown Sensor 12 to 24VDC * AC 2-wire Sensors Example: E3E2 etc. Brown Black Sensor Blue Blue 0V Operating Environment (1) Do not use a Sensor in an environment where there are explosive or inflammable gases. (2) Do not use the Sensor in environments where the cables may become immersed in oil or other liquids or where liquids may penetrate the Sensor. Doing so may result in damage from burning and fire, particularly if the liquid is flammable. http://www.ia.omron.com/ (c)Copyright OMRON Corporation 2007 All Rights Reserved. C-1 Photoelectric Sensors Technical Guide Precautions for Correct Use Design Power Reset Time Turning OFF Power The Sensor will be ready to detect within approximately 100 ms after the power is turned ON. If the Sensor and the load are connected to separate power supplies, turn ON the Sensor power before turning ON the load power. Any exceptions to this rule are indicated in Safety Precautions in individual product information. 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 Sensor 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 Sensors are affected by light from the adjacent Sensors. The following measures can be taken to avoid mutual interference. Countermeasure 1 2 Concept Through-beam Sensors Reflective Sensors Use a Sensor with the interference prevention function. If Sensors are mounted in close proximity, use Sensors with the interference prevention function. 10 or fewer Sensors: E3X-DA@-S, E3X-MDA, E3C-LDA Fiber Sensors Performance, however, will depend on conditions. Refer to pages E3X-DA-S/E3X-MDA and E3C-LDA. 5 or fewer Sensors: E3X-NA Fiber Sensors 2 or fewer Sensors: E3T, E3Z, E3ZM, E3ZM-C, E3S-C, E3G-L1/L3, or E3S-C Built-in Amplifier Photoelectric Sensors (except Through-beam Sensors) E3C Photoelectric Sensor with separate amplifier Install an inference prevention filter. A mutual interference prevention polarizing filter can be installed on only the E3Z-TA to allow close-proximity mounting of up to 2 Sensors. Mutual Interference Prevention Polarizing Filter: E39-E11 Separate Sensors to distance where interference does not occur. Check the parallel movement distance range in the catalog, verify the set distance between adjacent Sensors, and install the Sensors 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 Sensors by at least 1.5 times the operating range. 1.5 x L 3 Workpiece Workpiece L Sensor Alternate Emitters and Receivers. Sensor Close mounting of Sensors is possible by alternating the Emitters with the Receivers in a zigzag fashion (up to two Sensors). However, if the workpieces are close to the Photoelectric Sensors, light from the adjacent Emitter may be received and cause the Sensor to change to the incident light state. Emitter 4 --Workpiece Receiver Receiver Emitter Offset the optical axes. 5 6 Adjust the sensitivity. If there is a possibility that light from another Sensor may enter the Receiver, change the position of the Emitter and Receiver, place a light barrier between the Sensors, or take other measures to prevent the light from entering the Receiver. (Light may enter even if the Sensors are separated by more than the sensing distance.) If Sensors are mounted in opposite each other, slant the Sensors as shown in the following diagram. (This is because the Sensors may affect each other and cause output chattering even if separated by more than the Sensor sensing distance.) Sensor Sensor Lowering the sensitivity will generally help. http://www.ia.omron.com/ (c)Copyright OMRON Corporation 2007 All Rights Reserved. C-2 Photoelectric Sensors 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. Noise intrusion path and countermeasure Type of noise Before countermeasure After countermeasure Noise enters from the noise source through the frame (metal). +V Common mode noise (inverter noise) Sensor Inverter motor 0V IM Common noise applied between the mounting board and the +V and 0-V lines, respectively. (1) Ground the inverter motor (to 100 or less) (2) Ground the noise source and the power supply (0-V side) through a capacitor (film capacitor, 0.22 F, 630 V). (3) Insert an insulator (plastic, rubber, etc.) between the Sensor and the mounting plate (metal). Insert an insulator. Noise Mounting block (metal) +V Inverter motor Sensor 0V (3) (2) Noise Noise Mounting block (metal) Noise propagates through the air from the noise source and directly enters the Sensor. Radiant noise Ingress of high-frequency electromagnetic waves directly into Sensor, from power line, etc. Noise source (1) * Insert a shield (copper) plate between the Sensor and the noise source e.g., a switching power supply). * Separate the noise source and the Sensor to a distance where noise does not affect operation. +V Sensor Shield plate (copper) 0V Noise source Noise enters from the power line. Power line noise Noise Ingress of electromagnetic induction from high-voltage wires and switching noise from the switching power supply Noise IM +V Sensor +V Sensor 0V * Insert a capacitor (e.g., a film capacitor), noise filter (e.g., ferrite core or insulated transformer), or varistor in the power line. Noise 0V Insert a capacitor, etc. Noise Sensor +V 0V Wiring Cable Separation from High Voltage (Wiring Method) Unless otherwise indicated, the maximum length of cable extension is 100 m using wire that is 0.3 mm2 or greater. Exceptions are indicated in Safety Precautions in individual product information. Do not lay the cables for the Sensor 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 Sensor in a separate system, use an independent metal conduit, or use shielded cable. 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 Less than 4 mm 4 mm or greater Tensile strength 30 N max. 50 N max. Note: Do not subject a shielded cable or coaxial cable to tension. Repeated Bending 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. Normally, the Sensor cable should not be bent repeatedly. (For bending-resistant cable, see Attachment to Moving Parts on page C-4.) http://www.ia.omron.com/ (c)Copyright OMRON Corporation 2007 All Rights Reserved. C-3 Photoelectric Sensors Technical Guide Power Supply When using a commercially available switching regulator, ground the FG (frame ground) and G (ground) terminals. If not grounded, switching noise in the power supply may cause malfunction. Example of Connection with S3D2 Sensor Controller DC Three-wire NPN Output Sensors Reverse operation is possible using the signal input switch on the S3D2. Blue 0 V Black OUT Mounting Attachment to Moving Parts To mount the Photoelectric Sensor to a moving part, such as a robot hand, consider using a Sensors that uses a bending-resistant cable (robot cable). Although the bending repetition tolerance of a standard cable is approximately 13,000 times, robot cable has an excellent bending tolerance of approximately 500,000 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. 7 8 9 (2) 10 11 12 Brown +12 V (1) S3D2 4 5 6 1 2 3 (3) R Weight Specimen Description/conditions Test Bending angle () Bending repetitions Weight Operation per bending Bending radius of support points (R) Result Standard cable VR (H) 3 x18/0.12 Robot cable: Strong, conductive electrical wire 2 x 0.15 mm2, shielded Left/right 90 each Left/right 45 each --- 60 bends/minute 300g 200g (1) through (3) in figure once (1) through (3) in figure once 5 mm 2.5 mm Approx. 13,000 times Approx. 500,000 times The testing conditions of the standard cable and robot cable are different.

C-4 Photoelectric Sensors Technical Guide Adjustments Optical Axis Adjustment Securing Fibers The E3X 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. Move the Photoelectric Sensor 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 E3S-C, the optical axis and the mechanical axis are the same, so the optical axis can be easily adjusted by aligning the mechanical axis. Receiver Incident indicator or Operation indicator ON OFF Lock released position Emitter Locked position Lock lever Protective cover l 1 2 Insertion position Optimum value Incident indicator or Operation indicator ON OFF 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. Fiber insertion mark Fiber 9mm (2) Removing Fibers Open the protective cover, lift up the lock lever, and pull out the fibers. Locked position Lock released position Emitter Optical axis Optical axis Receiver Mechanical axis Protective cover Emission beam 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 -10 to 40C. http://www.ia.omron.com/ (c)Copyright OMRON Corporation 2007 All Rights Reserved. C-5 Photoelectric Sensors Technical Guide Operating Environment Water Resistance Maintenance and Inspection Points to Check When the Sensor Does Not Operate Do not use in water, in rain, or outside. * If the Sensor does not operate, check the following points. (1) Are the wiring and connections correct? (2) Are any of the mounting screws loose? (3) Are the optical axis and sensitivity adjusted correctly? (4) Do the sensing object and the workpiece speed satisfy the ratings and specifications? (5) Are any foreign objects, such as debris or dust, adhering to the Emitter lens or Receiver lens? (6) Is strong light, such as sunlight (e.g., reflected from a wall), shining on the Receiver? (7) Do not attempt to disassemble or repair the Sensor under any circumstances. (8) If you determine that the Sensor clearly has a failure, immediately turn OFF the power supply. Ambient Conditions Do not use this Sensor in the following locations. Otherwise, it may malfunction or fail. (1) Locations exposed to excessive dust and dirt (2) Locations exposed to direct sunlight (3) Locations with corrosive gas vapors (4) Locations where organic solvents may splash onto the Sensor (5) Locations subject to vibration or shock (6) Locations where there is a possibility of direct contact with water, oil, or chemicals (7) Locations with high humidity and where condensation may result Environmentally Resistive Sensors The E32-T11F/T12F/T14F/T81F-S/D12F/D82F and E3HQ can be used in locations (3) and (6) above. Optical Fiber Photoelectric Sensors in Explosive Gas Atmospheres The Fiber Unit can be installed in the hazardous area, and the Amplifier Unit can be installed in a non-hazardous area. For explosion or fire due to electrical equipment to occur, both the hazardous atmosphere and a source of ignition must be in the same location. Optical energy does not act as an ignition source, thus there is no danger of explosion or fire. The lens, case, and fiber covering are made of plastic, so this setup cannot be used if there is a possibility of contact with solvents that will corrode or degrade (e.g., cloud) the plastic. Electrical sparks or high-temperature parts that have sufficient energy to cause explosion in a hazardous atmosphere are called ignition sources. Hazardous area Non-hazardous area Fiber Unit Amplifier Unit Sensing object Lens and Case The lens and case of the Photoelectric Sensor are primarily made of plastic. Dirt should be gently wiped off with a dry cloth. Do not use thinner or other organic solvents. * The case of the E3ZM, E3ZM-C and E3S-C is metal. The lens, however, is plastic. Accessories Using a Reflector (E39-R3/R37/RS1/RS2/RS3) During Application (1) When using adhesive tape on the rear face, apply it after washing away oil and dust with detergent. The Reflector cannot be mounted if there is any oil or dirt remaining. (2) Do not press on the E39-RS1/RS2/RS3 with metal or a fingernail.This may weaken performance. (3) This Sensor cannot be used in locations where oil or chemicals may splash on the Sensor. M8 and M12 Connectors * Be sure to connect or disconnect the connector after turning OFF the Sensor. * Hold the connector cover to connect or disconnect the connector. * Secure the connector cover by hand. Do not use pliers, otherwise the connector may be damaged. * If the connector is not connected securely, the connector may be disconnected by vibration or the proper degree of protection of the Sensor may not be maintained. Others Influence from External Electrical Fields Values Given in Typical Examples Do not bring a transceiver near the Photoelectric Sensor or its wiring, because this may cause incorrect operation. The data and values given as typical examples are not ratings and performance and do not indicate specified performance. They are rather values from samples taken from production lots, and are provided for reference as guidelines. Typical examples include the minimum sensing object, engineering data, step (height) detection data, and selection list for specifications. Cleaning * Keep organic solvents away from the Sensor. Organic solvents will dissolve the surface. * Use a soft, dry cloth to clean the Sensor. http://www.ia.omron.com/ (c)Copyright OMRON Corporation 2007 All Rights Reserved.
