Photoelectric Sensor with Built-in Amplifier (Ultracompact and Thin Type) E3T CSM_E3T_DS_E_9_1 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. Features 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 E3TFL1@ 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 Convergentreflective Sensors.

Do not use it for such purpose. Do not apply AC power to the E3T, otherwise the E3T may rupture. Stable operation range* Precautions for Correct Use Do not use the product in atmospheres or environments that exceed product ratings. Unstable operation range* Stable operation range* ● 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 shortcircuit 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. Light • The following graphs indicate the status of each operating level. • Be sure to use the E3T within the stable operating range. Stability indicator (green) Operation indicator (orange) E3T-@@@1 E3T-@@@2 E3T-@@@3 E3T-@@@4 ON Operating level x 1.2 Operating level Operating level x 0.8 ON OFF OFF ON OFF ON *If the E3T fs operating level is set to the stable operation range, the E3T will be in most reliable operation without being influenced by temperature change, voltage fluctuation, dust, or setting change. If the operating level cannot be set to the stable operation range, pay attention to environmental changes while operating the E3T. Use of E39-E10 Sensitivity Adjustment Unit (Dark-ON: E3T-ST12) (At Min) (At Center) (At Max.) Indicator Adjuster ● 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. Specimen B A C θ θ R 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. Weight Standard cable Robotics cable 2.4-mm dia. 2.4-mm dia.
