LM10 Series MICRO LASER SENSORS DISPLACEMENT LASER SENSOR Shape recognition Position displacement measurement Thickness measurement Resolution Measurement The LM10's cost-performance ratio far outstrips the competition. Measuring sensors Detection LM10 High-precision position fixing High-precision detection of presence/absence Simple position fixing Detection of presence/absence General purpose photoelectric sensors Price High-precision measurements with comparative output function New circuitry lowers costs. In addition to conventional analog output, the LM10 also comes with ON/OFF control outputs;single (high/low outputs) or double (high/low/go outputs) comparators. This gives the LM10 the versitility of both a photoelectric sensor and a high precision laser. nel. Building the arithmetic circuits into the IC has also helped to reduce costs.

Intensity control: ON/OFF control on the basis of received light level. Power circuit * Measurement principle of the LM10 (optical triangulation) Part of the light rays which come from the target object by means of diffuse reflection are focused to produce a light spot on the position sensing device (PSD). The location of this light spot varies depending on the distance of the target object. By measuring the change in the location of the light spot, the LM10 can measure the displacement of the target object. Position sensing device (PSD) Light receptor lens a b Light receptor Light projector Light projector lens Light element (semiconductor laser) Center point A Measurable range Signal processing circuit B Controller LM10 Use the LM10 with confidence. It meets FDA standards for class 2 laser safety. Products available in two series: laser class 2 high and low power. Development of a high-precision aspheric surface plastic lens has made it possible to maintain both high precision and class 2 safety. The visible light spot makes it easy to see and safe to use. Interchangeable sensor heads Sensor head and controller can be managed separately. Nine types of sensor heads and eight types of controllers can be freely combined in 72 different ways. Unlike those of conventional laser sensors, these heads and controllers are completely interchangeable to meet any type of measuring and processing requirements, There is no need for matched pair management of heads and controllers. Excellent in the following circumstances... * When carrying out repairs * When changing to a different model. Suppose an accident on the production line damages the sensor head.

Procedure for setting the sensor 1) While watching the range indicator LED, set the sensor so that the distance to the subject body is within the measurable range. Measurement range indicator LED Off Flashing On Flashing Off Outside of measurable range Center of measurement range Outside of measurable range 2) Be careful of the sensor's orientation during installation. When the subject body moves as shown below, errors will develop depending on the orientation of the sensor. In order to minimize these errors, be sure to install the sensor in the correct orientation. * Step detection * Concentricity measurement 2. Installing the sensor 1) Using the two installation holes, firmly install the sensor so that the sensor's front surface is parallel to the target. Do not tighten the installation screws to a torque over 2 N*m. 2) Glass is used at the sensor's light emission and light reception surfaces and, therefore, never subject it to impacts of any kind. Also, be very careful not to allow oils, fingerprints, or other substances that may refract the light, to get on the glass during installation. 3) If light reflected off the target is then reflected off nearby objects or walls and then received by the sensor, the sensor reading will be adversely affected. To prevent this, either further separate the sensor or apply a black delustering paint to prevent the unwanted reflection of light. 3. Installing the controller 1) When installing more than one controller in a row, maintain at least 10 mm between each unit. Also, when installing the controller inside control panels or other areas where the air is not properly ventilated, the controller will cause the ambient temperature to rise. In these cases, ensure the proper cooling facilities. 4. Wiring 1) Perform all wiring by faithfully following the input and output circuit explanations and documents that came with the instrument. 2) When installing or removing a connector, always first turn off the controller and then begin operations. 3) All connectors are of the lock-on type. When connecting a connector, be sure to securely insert it until it locks into place. When removing a connector, first press in the lock release button on the connector side and then remove the connector. * Extremely different adjacent colors or materials Lock release button 4) After removing a connector, do not touch the terminals located inside. 5) The connector's metal portion is internally connected to the analog output GND. In order to prevent affects from noise or damage to the internal circuits, be sure to insulate the metal portion with electrical tape or other means. 5. Cable 1) When the sensor and controller are fixed and cables connected, do not subject the cables to a pull of more than 3 kg. Have no bends in the cables with a radius of less than 20 mm. Also, do not bend a sensor's cable near where the cable is attached to the sensor. 2) When the sensor is to be moved while in use, do not have it so that the sensor's cable becomes bent. If the location is such that it cannot be helped, we recommend purchasing the appropriate length extension cable so that bending is unnecessary. R20 .787 or more Precautions during operation 6) Keep the sensor light emitter and light receptor surface clean and free of moisture, oil, finger prints, and other light refracting substances, and free of dust, dirt, and other light blocking substances. When cleaning the glass surfaces, wipe with a soft cloth or lens cleaning paper. 7) Although the sensor is of waterproof construction, it does not mean that measurements can be taken underwater or in the rain. Moreover, the connectors are not watertight. 8) Do not use the unit in locations with flammable or corrosive gases, locations with excessive dust, locations splashed by water, or locations subjected to vibrations or excessive shocks. 9) Since the controller contains molded resins, do not use in environments that contain, or where contact with, benzene, thinners, alcohols and other organic solvents; and ammonia, caustic sodas, and other alkaline substances is possible. 2. Noise precautions 1) Install the unit as far away as possible from high voltage wires, power wires, or devices that generate large switching surges. 2) Separate the sensor cable wiring, high voltage circuit, and power circuit. 3) If there is much noise on the power supply, it will affect the analog output. In such cases, use a noise filter or noisecut transformer. 1. Operating environment 1) Use in an ambient temperature between 0 C 32 F and 50 C 122 F. Store in a location where the temperature stays between -20 C -4 F and 70 C 158 F. 2) Use in an ambient humidity between 35 % and 85 % RH. Avoid use in locations with drastic humidity changes which cause condensation. 3) Use in a location where the illuminance from incandescent lamps received at the light receptors surface is below 2,500 lx (ANR11 series and ANR1226), or below 3,000 lx (ANR1250, ANR1251, ANR1282, and ANR1215). Also, locate the unit so that sunlight, light of the same wavelength, or other disturbing light, does not directly hit the light receptor. When exceptional accuracy is required, install a shielding plate or other type of shading mechanism. 4) The power supply voltage should be between 85 % and 110 % of the rated voltage. 5) Since the internal circuits may become damaged if an external surge voltage exceeds 500 V [(1.2 x 50) s unipolar full-wave voltage], always use a surge absorber or surge absorbing element. 3. Insulation resistance and withstand voltage 1) Do not perform insulation resistance or withstand voltage tests between the connector's metal portions and input/outputs. 4. Power supply 1) Select a power supply with a ripple voltage below 0.5 V (P-P) and a current capacity above 0.3 A. 2) In order to avoid high-frequency noises when using an off-the-market switching regulator, be sure to ground the frame ground (FG) terminal. 3) When using a power supply that uses a transformer, be sure to use an insulated transformer. When using an autotransformer (single-wound transformer), it is possible to damage this unit or the power supply. 5. Warm-up time 1) Allow at least 30 minutes, after turning on the unit, for the unit to properly warm up.
