Beam size: The beam size is defined by /e (.5%) of the strength of the beam at the beam center (measured value). Incorrect detection may occur if there is light leakage outside the defined spot and the material around the sensing object is more reflective than the sensing object. *. Resolution: The resolution is the deviation (±σ) in the linear output when connected to the Z-LDA Amplifier Unit. (The resolution is measured with the standard reference object (white ceramic), at the measurement point with the Z-LDA set for an average count of,96 per period.) The resolution is given at the repeat accuracy for a stationary workpiece, and is not an indication of the distance accuracy. The resolution may be adversely affected under strong electromagnetic fields. *. Linearity: The linearity is given as the error in an ideal straight line displacement output when measuring the standard reference object. The linearity and measurement values vary with the object being measured. *. Temperature characteristic: The temperature characteristic is measured at the measurement point with the Sensor and reference object (OMRON s standard reference object) secured with an aluminum jig. Note: Highly reflective objects can result in incorrect detection by causing out-of-range measurements. Z Series (Z-L-N) Smart Sensors (Laser Type)

16 Precautions Design Precautions Ratings and Performance Conform to the specified ratings and performance. Refer to Specifications for details.. Do not impose voltage exceeding the rated voltage, otherwise the Sensor may be damaged.. When supplying power to the Sensor, make sure that the polarity of the power is correct, otherwise, the Sensor may be damaged. Do not connect to an AC power supply.. Do not short-circuit the load for the open collector output, otherwise the Sensor may be damaged. Do not disconnect the connector connecting the Sensor Head and the controller while power is being supplied, otherwise the Sensor may be damaged. Allow a warm-up period of approximately minutes after turning ON the power supply. Objects of certain materials or shapes may not be detectable, or the detection accuracy may not be sufficiently high. These include materials that are transparent or have extremely low reflectivity, and objects that are smaller than the Sensor s spot diameter or have extreme curvature or inclination. Other Precautions Environment. Do not use the Sensor in strong electromagnetic fields or in an environment where the operation of the Sensor is subject to the reflection of intense light (such as other laser beams or electric arc-welding machines.). Do not operate the Sensor in the following locations: Locations subject to strong vibration. Locations subject to direct sunlight or near heating equipment. Locations subject to high humidity. Locations where the Sensor would accumulate dust, dirt, metallic powder, etc. Locations subject to corrosive or flammable gases. Locations subject to exposure to organic solvents, water, oil, etc. Locations subject to strong electromagnetic or electrical fields. Locations subject to rapid changes in temperature. Locations subject to freezing. Power Supply and Wiring Prior to turning ON the power supply after wiring is completed, check to make sure that the power supply is correct, that there are no mistaken connections, e.g., connections that would short-circuit the load, and that the load current is appropriate. Incorrect wiring may result in damage to the Sensor or Unit. The total length of the Sensor cable or Amplifier cable must be m or less. Use an Z-C@A Extension Cable (order separately) if required to extend the cable from the Sensor. Use a shielded cable to extend the Amplifier cable. The shielded cable must be the same as that of the Amplifier cable. Do not lay a power supply cable for the Z together with high-voltage lines or power lines to prevent interference, damage, and malfunction. When using a commercially available switching regulator, ground the FG (frame ground) terminal. If the power supply line is subject to surges, connect a surge absorber that meets the conditions of the usage environment. When using a Calculating Unit, connect the corresponding linear ground of the Amplifier Unit. Compatibility All Sensor Heads and Amplifier Units are compatible. Different Sensor Heads may be purchased at a later date and used with existing Amplifier Units. Mutual Interference Two Sensor Heads can be used together, without danger of mutual interference, by connecting the Z-CAL Calculating Unit between two Amplifier Units. Maintenance Always turn OFF the power supply before adjusting or removing the Sensor Head. Cleaning Do not use thinners, benzine, acetone, or kerosene for cleaning. If dust or oil adheres to the filter on the front of the Sensor Head, use the following procedure to clean.. Use a blower brush (used to clean camera lenses) to blow large dust particles from the surface. Do not blow the dust away with your mouth.. Use a soft cloth (for lenses) with a small amount of alcohol to remove the remaining dust. Do not use a scrubbing action when cleaning because scratches on the filter could result in Sensor inaccuracy. 6 Z Series (Z-L-N) Smart Sensors (Laser Type)

For other wavelengths the hazard to the unaided eye is no greater than for Class. Direct intrabeam viewing of Class A lasers with optical aides (e.g., binoculars, telescopes, microscopes) may be hazardous. Direct intrabeam viewing of these lasers is always hazardous. Viewing diffuse reflections is normally safe (see note). Lasers which are also capable of producing hazardous diffuse reflections. They may cause skin injuries and could also constitute a fire hazard. Their use requires extreme caution. Note: Conditions for safe viewing of diffuse reflections for Class B visible lasers are: minimum viewing distance of cm between screen and cornea and a maximum viewing time of s. Other viewing conditions require a comparison of the diffuse reflection exposure with the MPE. Z Series (Z-L-N) Smart Sensors (Laser Type)

22 Comparison of Classifications between FDA and ANSI Class FDA definition ANSI description Class I/ Limits applicable to devices that have emissions in the ultraviolet, visible, and infrared spectra, and limits below which biological hazards have not been established. A Class laser is considered to be incapable of producing damaging radiation levels during operation and maintenance and is, therefore, exempt from any control measures or other forms of surveillance. Class IIa/a Class II/ Class IIIa/a Class IIIb/b Class IV/ Label Indications EN Limits applicable to products whose visible emission does not exceed Class I limits for emission durations of, seconds or less and are not intended for viewing. Limits applicable to products that have emissions in the visible spectrum ( to 7 nm) for emission durations in excess of.5 second, providing that emissions for other durations and/or wavelengths do not exceed the Class I limits. Class II products are considered hazardous for direct long-term ocular exposure. Limits to products that have emissions in the visible spectrum and that have beams where the total collectable radiant power does not exceed 5 milliwatts. Limits applicable to devices that emit in the ultraviolet, visible, and infrared spectra. Class IIIb products include laser systems ranging from 5 to 5 milliwatts in the visible spectrum. Class IIIb emission levels are ocular hazards for direct exposure throughout the range of the Class, and skin hazards at the higher levels of the Class. Exceeding the limits of Class IIIb and are a hazard for scattered reflection as well as for direct exposure. Class lasers are divided into two subclasses, and a. A Class laser emits in the visible portion of the spectrum (. to.7 µm) and eye protection is normally afforded by the aversion response including the blink reflex. Class lasers are divided into two subclasses, a and b. A Class laser may be hazardous under direct and specular reflection viewing conditions, but the diffuse reflection is usually not a hazard. A Class laser is a hazard to the eye or skin from the direct beam and sometimes from a diffuse reflection and also can be a fire hazard. Class lasers may also produce laser-generated air contaminants and hazardous plasma radiation.
