PM2 SERIES Convergent Reflective Micro Photoelectric Sensor Convergent reflection sensing ensures stable detection Stable detection by convergent reflective mode Not affected by background Dark object detectable Stable detection characteristics are obtained since it is convergent reflective type and senses a limited area. Even a specular background does not affect the sensing performance if the sensor is located 30 mm 1.181 in away from it. Since the sensor is very sensitive, it can detect even a dark object of low reflectivity. ( 314 However, the specular background should be a plane surface, directly facing the sensor. A spherical or curved background may be detected. ) Minute object detectable Cable type is also available A "0.05 mm "0.002 in copper wire can be detected at a distance of 5 mm 0.197 in. Cumbersome soldering is not required. It saves space and improves reliability. 08/2005 PM2 APPLICATIONS Sensing capacitors in a tray Sensing printed circuit boards ORDER GUIDE Appearance Sensing range Front sensing L type (Top sensing) Connector type Top sensing Type Output Light-ON PM2-LH10B Dark-ON PM2-LF10 Light-ON PM2-LF10B Dark-ON PM2-LL10 Light-ON Top sensing 2.5 to 8 mm 0.098 to PM2-LH10-C1 0.315 in Front sensing point: ( Convergent 5 mm 0.197 in ) Output operation PM2-LH10 PM2-LL10B L type (Top sensing) Cable type Model No. Dark-ON NPN open-collector transistor Light-ON PM2-LH10B-C1 Dark-ON PM2-LF10-C1 Light-ON PM2-LF10B-C1 Dark-ON PM2-LL10-C1 Light-ON PM2-LL10B-C1 Dark-ON OPTIONS Designation Connector Model No. Description CN-13 Dedicated connector CN-13-C1 0.2 mm2 3-core cabtyre cable, 1 m 3.281 ft long CN-13-C3 0.2 mm2 3-core cabtyre cable, 3 m 9.843 ft long Connector Mating cable * CN-13 * CN-13-C1 * CN-13-C3 Mating cable 08/2005 315 PM2 SPECIFICATIONS Connector type Type Item Model Light-ON No. Dark-ON Sensing range Cable type Top sensing Front sensing L type (Top sensing) Top sensing Front sensing L type (Top sensing) PM2-LH10 PM2-LF10 PM2-LL10 PM2-LH10-C1 PM2-LF10-C1 PM2-LL10-C1 PM2-LH10B PM2-LF10B PM2-LL10B PM2-LH10B-C1 PM2-LF10B-C1 PM2-LL10B-C1 2.5 to 8 mm 0.098 to 0.315 in (Conv. point: 5 mm 0.197 in) with white non-glossy paper (15 15 mm 0.591 in0.591 in) (Note 1) Min. sensing object "0.05 mm "0.002 in copper wire (Setting distance: 5 mm 0.197 in) 20 % or less of operation distance with white non-glossy paper (1515 mm 0.5910.591 in) Hysteresis Repeatability (perpendicular to sensing axis) 0.08 mm 0.003 in or less (Note 2) 5 to 24 V DC10 % Ripple P-P 5 % or less Supply voltage Current consumption Average: 25 mA or less, Peak: 80 mA or less NPN open-collector transistor * Maximum sink current: 100 mA * Applied voltage: 30 V DC or less (between output and 0 V) * Residual voltage: 1 V or less (at 100 mA sink current) 0.4 V or less (at 16 mA sink current) Output Utilization category DC-12 or DC-13 Short-circuit protection Incorporated Response time 0.8 ms or less Environmental resistance Operation indicator Red LED (lights up when the output is ON) Pollution degree 3 (Industrial environment) 10 to55 C 14 to131 F (No dew condensation or icing allowed), Storage: 25 to80 C 13 to176 F Ambient temperature Ambient humidity 45 to 85 % RH, Storage: 45 to 85 % RH Sunlight: 11,000 #x at the light-receiving face, Incandescent light: 3,500 #x at the light-receiving face Ambient illuminance EMC EN 50081-2, EN 50082-2, EN 60947-5-2 Vibration resistance 10 to 55 Hz frequency, 1.5 mm 0.059 in amplitude in X, Y and Z directions for two hours each Shock resistance 500 m/s2 acceleration (50 G approx.) in X, Y and Z directions for three times each Emitting element Infrared LED (modulated) Enclosure: Polycarbonate, Terminal part: HSM (Ag plated) Material Enclosure: Polycarbonate, Fixed cable part: PBT 0.2 mm2 3-core cabtyre cable, 1 m 3.281 ft long (Note 3) Cable Cable extension Weight ( Total 2 m 6.562 ft is possible with 0.3 mm2, or more, cable.

Symbols ... ZD: Surge absorption zener diode Tr : NPN output transistor SENSING CHARACTERISTICS (TYPICAL) Sensing fields * Horizontal (left and right) direction * Vertical (up and down) direction The sensors can be mounted side by side. However, if the sensor is slanted, there may be interference. Verify first whether there is any interference prior to use. Correlation between lightness and sensing range The sensing region is represented by oblique lines in the left figure. However, the sensitivity should be set with enough margin because of slight variation in products. ( Lightness shown on the left may differ slightly from the actual object condition. The sensors can be mounted side by side. However, if the sensor is slanted, there may be interference. Verify first whether there is any interference prior to use. Correlation between material (1515 mm 0.5910.591 in) and sensing range The bars in the graph indicate the sensing range for the respective material. However, there is a slight variation in the sensing range depending on the product. Further, if there is a reflective object (conveyer, etc.) in the background of the sensing object, since it affects the sensing, separate it by more than twice the sensing range shown in the left graph. ) 08/2005 317 PM2 PRECAUTIONS FOR PROPER USE Connector type All models This product is not a safety sensor. Its use is not intended or designed to protect life and prevent body injury or property damage from dangerous parts of machinery. It is a normal object detection sensor. Cautions in plugging or unplugging a connector * Do not plug or unplug a connector more than 10 times. * Be sure not to give stress more than 5 N to a terminal of both a connector and a sensor. If you do not follow the above cautions, it will cause a poor contact. Mounting * When fixing the sensor with screws, use M3 screws and the tightening torque should be 0.49 Nm or less. Further, use small, round type plain washers ("6 mm "0.236 in). Procedures of plugging or unplugging a connector 1Insert a connector straight into a sensor until the connector lug is locked by the sensor hook. Wiring * Make sure to connect terminals correctly as the sensor does not incorporate a reverse polarity protection circuit. * If the sensor is being used in a noisy environment, examine the extent of noise. Further, if equipment, such as motor, solenoid or electromagnetic valve, which generates a large surge, is present near the sensor, connect a surge absorber to the equipment. Setting * The optimum setting distance (distance to convergent point) is 5 mm 0.197 in. The sensor is not affected even by a specular background if it is located 30 mm 1.181 in, or more, away from the sensor. However, the specular background should be a plane surface, directly facing the sensor. A spherical or curved background may be detected. ( 2When unplugging, give as much stress as a connector lug can be relieved from a hook. Then unplug it. Caution: Be sure to hold a connector when plugging or unplugging it. Do not hold a terminal or a cable when plugging or unplugging the connector. Otherwise, it will cause a poor contact. Soldering (Both connector CN-13 and sensor) * If soldering is done directly on the terminals, strictly adhere to the conditions given below. Soldering temperature Soldering time ) 260 C 500 F or less 10 sec. or less Soldering position Refer to the below figure Sensor Others * Do not use during the initial transient time (50 ms) after the power supply is switched on. * Take care that the product does not come in direct contact with oil, grease, or organic solvents, such as, thinner, etc. Wiring * The cable length must be 2 m 6.562 ft, or less, with 0.3 mm2, or more, cable. If the cable is extended for more than 2 m 6.562 ft, connect a capacitor of 10 !F approx. between V and 0 V terminals. 318 08/2005 Connector PM2 DIMENSIONS (Unit: mm in) PM2-LH10 PM2-LH10B Sensor PM2-LL10 PM2-LL10B Sensor PM2-LF10 PM2-LF10B Sensor m Terminal part (Connector type) CN-13 Connector (Optional) 08/2005 319 PM2 DIMENSIONS (Unit: mm in) PM2-LH10-C1 PM2-LH10B-C1 Sensor PM2-LL10-C1 PM2-LL10B-C1 Sensor 320 PM2-LF10-C1 PM2-LF10B-C1 08/2005 Sensor
