088-093/MR3 0.6.10 12:21 Page 1 LONG RANGE TRIGONOMETRIC AREA REFLECTIVE PHOTOELECTRIC SENSORS (AC OR DC POWER) FEATURES Long range sensors. The first long distance optical triangulation photoelectric sensors for 1 m 3.281 ft. and 2 m 6.562 ft. applications.Suitable for detection of passing targets and positioning. New added type with timer functions. The 3-mode (ON-delay, OFF-delay, One-shot) timer function is built-in the MR3-T type, to prevent detection errors and make it easier to send a high speed signal to a PC etc. The control time range is from 0.1 to 5 sec. AC or DC power The DC type operates by 12 to 24 V DC and the AC-DC type by 12 to 240 V DC or 24 to 240 V AC power supply. This allows operation voltages world wide. Accurately detects objects, regardless of colors, materials and shapes. Area reflective type sensor permits the detection of white and black targets at the same distance. Also targets with mixed colors, difficult to detect with standard diffuse reflective type sensors, can be detected. Unaffected background objects. Area reflective type sensors do not detect objects beyond the set point. False detection, caused by movement beyond detectable objects, does not occur. Tolerates dirty lens with consistent position detection. There is virtually no variation in the operation even if the lens surface becomes dirty. Position detection of targets approaching from the front is always constant. Various outputs selectable Two outputs are provided for the DC type, NPN and PNP output, so that a single photoelectric sensor can match the polarity of the power supply wiring.The output section of the AC/DC type contains compact 1 Form A contact rated 3 A, 250 V AC (resistive). MR3/MR3-T Series Designed for easy installation and adjustment. * Screw terminals for easy wiring. * One-touch switch for mode selection.

This will ensure stable operation. DISTANCE ADJUSTMENT 1) Point the detection surface of the photoelectric sensor in the direction to detect and temporarily fasten. 2) Set the distance adjustment dial to its maximum setting FAR. Slowly turn it counterclockwise without an object present and note the position where the operation (light) indicator LED turns OFF. The maximum position at which the LED turns off is the FAR position. 3) Place a target at the detection position and set the distance adjustment dial to its minimum setting NEAR. Slowly turn it clockwise and note the operation (light) indicator LED turns ON. The minimum position at which the LED turns ON is the NEAR position. 4) Set the distance adjustment dial to the middle of the two positions found in step 2) and step 3) before. 5) Fasten the photoelectric sensor. Mount securely so that the photoelectric sensor is not shifted from alignment by vibrations or impact. Distance adjustment dial Operation indicator LED Adjuster LED (Light indicator LED) Notes 1. If the adjuster LED does not turn ON in 4) (note that there is no adjuster LED for the MR3-T timer type), or if the position LED for the distance adjustment dial in 2) ( or 3) is less than 2 graduations, either change the position of the detection surface and repeat 1) to 4), or adjust external factors such as ambient temperature variations, position of target, etc. 2. The detection distance varies only slightly with the color of the target. However, if the target has extremely low reflection factor (mirrors, glass, glossy paper and other specular reflective objects), adjustment of the detectable distance may not be applied to the distance adjustment dial, otherwise it may be damaged. For the MR3-T timer type, see the words in the ( ).

The voltage applied to the load relay is the operating voltage of the photoelectric sensor minus the internal voltage drop (maximum 1.2V NPN side, 2V PNP side). Voltage fluctuations should be taken into account. 7) The output circuit of the DC type contains a short-circuit protection circuit. When controlling loads with a large inrush current, such as capacitive loads, be sure the inrush current does not exceed the maximum output current 5. Other cautions 1) When using the supplied mounting bracket, tighten the mounting screws with a maximum torque of 8 N*m{78.4 kgf*cm 68.00 lbf*in}. If the supplied mounting bracket is not used, mount the sensor on a flat surface. 2) Using a torque of 3 to 5 N*m{29.4 to 49 kgf*cm 25.48 to 42.53 lbf*in}, tighten the terminal cover and display cover screws to maintain watertight performance.

Operating Environment 1) The sensor should be used in an ambient temperature range of -25 to +55C -13 to +131F. 2) Use an operating voltage in the range of 9.6V to 30 V DC (includes peak to peak ripple) for the DC types and 21.6V to 264V AC or 10.8V to 264V DC for the AC/DC types. 3) The light intensity on the receiver surface should be less than 3,000 lux for an incandescent light source and less than 10,000 lux for sunlight. 4) Use a surge absorber as the internal circuit may be damaged if external surge voltages exceed 5..V (for DC type)/4,000V (for AC/DC type) [(1.2T50)s signal polarity full-wave voltage]. capacity. If the short-circuit is activated, it can be reset either by turning the power off and then turning it back on, or by ON/OFF operation. 2. Wiring 1) Check all wiring before applying power since incorrect wiring may damage the internal circuit. Also, carefully tighten the terminal screws so that the wires of adjacent terminals do not touch. 2) Although any cable can be used, a round cable with a smooth surface and an outside diameter of 9 to 11 mm .354 to .433 inch should be used and the cable connector (supplied) shall be tightened correctly to maintain watertight performance. Use a tightening torque of 15 to 20 N*m {147 to 196 kgf*cm 127.60 to 170.03 lbf*in}. 3) the conduit inlet accepts PF1/2 threads. 4) If crimp terminals are used, crimp the terminals and then secure with the terminal (M3.5) screws. 5) Tighten the terminal screws with a maximum torque of 5 N*m{49 kgf*cm 42.53 lbf*in}. 6) Ground the frame ground (FG) terminal and ground (G) terminal when using a commercially available switching regurator. If a ground is not connected, switching noise from the power supply may result in faulty operation. 7) Wire 0.3 mm2 0.005 inch2 AWG22 or larger should be used for wiring up to a length of 100 m 328 ft. 3. Detector 1) Keep the detector surface clean as excessive dust or dirt on the detector surface will decrease the margin of the distance range. 2) The front surface of the lens and case are made of polycarbonate resin. Although it withstands water, weak acids and alkalines, aliphatic hydrocarbons, and oils and fats, it is not resistant to ketones, esters, halogenated hydrocarbons and aromatic hydrocarbons. 4.
