E3T-SR4@ : Retro-reflective Sensor with Enhanced Compactness and High Performance

  • Perform detection from a small hole. With a coaxial optical system, the lens diameter is only 2 mm. Sufficient incident light is obtained even through a small hole. The Coaxial Retro-reflective Sensor can be used for reliable application with positioning.  Improved Stability of Short-distance Detection A detection distance as short as 10 mm can be used with a Tape Reflector. Detection is stable through a hole whether the distance is 10 mm or 100 mm (except in combination with the E39-R4). E3T-FL1@/-FL2@: The Slimmest BGS (Background Suppression) Reflective Photoelectric Sensors in the World Ultra slim at 3.5 mm and black/white error of only 15%. For example, the E3T- FL1@ can stably detect a black object at 12 mm without being affected by a white background at 20 mm. OMRON provides BGS performance sharper than the previous Convergent- reflective Sensors. Dramatic Improvement in Black/White Error 3.5mm E3T -FL1 20mm 12mm 15mm Not detected Detected Black object White background Rated sensing distance 25(mm) White paper Black paper White paper Black paper E3T -FL1 (BGS Reflective Model) E3T -SL1 (Convergent-reflective Model) New Retro-reflective Sensors Added to the Series. Further Contributions to Equipment Downsizing.  Coaxial Retro-reflective for reliable positioning applications.  Series now includes BGS* reflective model with black/white error of 15%  Easy optical axis adjustment with emitter axis accuracy of ±2° (Through-beam Model)  Noise and external light resistance enhanced to that of E3Z or equivalent  Output reverse polarity protection provides reliable support against incorrect wiring.  The Series includes models with M12 Smartclick pre-wired connectors (-M1TJ) * BGS (Background Suppression) technology prevents detecting background objects. Be sure to read Safety Precautions on page 14.

Ordering Information

Sensors (Refer to Dimensions on page 15.) *1. Values in parentheses indicate the minimum required distance between the Sensor and Reflector. *2. The model number of the Emitter is expressed by adding an "L" to the set model number in the table. Example: E3T-ST11-L 2M The model number of the receiver is expressed by adding a "D" to the set model number in the table. Example: E3T-ST11-D 2M Orders for individual Emitters and Receivers are accepted. (Modifications are required for some models.) *3. Ask your OMRON representative about the previous Retro-reflective Sensors: E3T-SR2@ and E3T-SR3@. *4. Models are available either with or without the E39-R37-CA Reflector included.

Refer to Warranty and Limitations of Liability. This product is not designed or rated for ensuring safety of persons. Do not use it for such purpose. Do not apply AC power to the E3T, otherwise the E3T may rupture. Do not use the product in atmospheres or environments that exceed product ratings.

  • Wiring The maximum power supply voltage is 24 VDC +10%. Before turning the power ON, make sure that the power supply voltage is not more than maximum voltage. Load short-circuit protection The E3T incorporates a load short-circuit protection function. If the load short-circuits, the output of the E3T will be turned OFF . Then, recheck the wiring and turn on the E3T again to reset the load short- circuit protection function. The load short-circuit protection function will work if there is a current flow that is 1.5 times larger than the rated load current. When using a capacitance load, be sure that the inrush current will not exceed 1.5 times larger than the rated current.
  • Mounting When mounting the Sensor, never strike it with a heavy object, such as a hammer. Doing so may reduce its watertight properties. Use M2 screws and flat or spring washers to secure the Sensor. (Tightening torque: 0.15 N·m max.) Mounting the Sensor on Moving Parts Consider models that use break resistant cables (e.g., Robotics Cables) if the Sensor will be mounted on a moving part, such as a robot hand. The flexing resistance of Robotics Cable at approximately 400 thousand times is far superior to that of standard cable at approximately 14 thousand times. Cable Bending Rupture Test (Tough Cable Breaking Test) The cable is repeatedly bent with power supplied to check the number of bends until the current is turned OFF .
  • Adjusting Indicators
  • The following graphs indicate the status of each operating level.
  • Be sure to use the E3T within the stable operating range. Use of E39-E10 Sensitivity Adjustment Unit (Dark-ON: E3T-ST12) 1. Mount the Unit on the Receiver. 2. Set the adjuster of the Sensitivity Adjustment Unit to Max. (Before shipping: Max.) 3. After mounting on the Sensor, adjust the optical axis and secure the Sensor. 4. Place a workpiece between the Emitter and Receiver and gradually turn the adjuster counterclockwise toward the Min. side. Stop turning the adjuster when the operation indicator and stability indicator (green) turn ON. 5. Remove the workpiece and confirm that the operation indicator is OFF and the stability indicator (green) is ON. This completes the adjustment. Note: If the light attenuation rate due to a workpiece is 40% or less, the stability indicator will not turn ON whether or not light is received. When the variation of light is small such as when sensing semi-transparent workpieces, carefully perform preliminary testing.
  • Others Do not install the E3T in the following locations.
  • Locations subject to excessive dust or dirt
  • Locations subject to direct sunlight
  • Locations subject to corrosive gas
  • Locations subject to contact with organic solvents
  • Locations subject to vibration and shock
  • Locations subject to contact with water, oil, or chemicals
  • Locations subject to high humidities that might result in condensation WARNING Precautions for Correct Use Specimen Standard cable 2.4-mm dia.

Disclaimers CHANGE IN SPECIFICATIONS Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made. However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual specifications of purchased products. DIMENSIONS AND WEIGHTS Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown. PERFORMANCE DATA Performance data given in this catalog is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Actual performance is subject to the OMRON Warranty and Limitations of Liability. ERRORS AND OMISSIONS The information in this document has been carefully checked and is believed to be accurate; however, no responsibility is assumed for clerical, typographical, or proofreading errors, or omissions. 2010.2 In the interest of product improvement, specifications are subject to change without notice.
