1 Photoelectric Sensor with Built-in Amplifier (Ultracompact and Thin Type) ET Photoelectric Sensor with Built-in Amplifier Contributes to Equipment Downsizing CSM_ET_DS_E Ultracompact and Thin Photoelectric Sensor with Built-in Amplifier Easy optical axis adjustment with emitter fluctuation of ±% max. for Through-beam Models. Product lineup includes Coaxial Retro-reflective Models that support positioning applications. Product lineup includes BGS* Reflective Models unaffected by background Product lineup of models with a variety of connection specifications. (e.g., robot cable and Smartclick pre-wired connectors) * BGS (Background Suppression) technology prevents detecting background objects. Be sure to read Safety Precautions on page. Features ET-SR@ : 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 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 mm can be used with a Tape Reflector. Detection is stable through a hole whether the distance is mm or mm (except in combination with the E9-R). ET-FL@/-FL@: The Slimmest BGS (Background Suppression) Reflective Photoelectric Sensors in the World Ultra slim at. mm and black/white error of only %. For example, the ET- FL@ can stably detect a black object at mm without being affected by a white background at mm. OMRON provides BGS performance sharper than the previous Convergentreflective Sensors.

14 Safety Precautions Refer to Warranty and Limitations of Liability. WARNING This product is not designed or rated for ensuring safety of persons. Do not use it for such purpose. ET Adjusting Indicators The following graphs indicate the status of each operating level. Be sure to use the ET within the stable operating range. Do not apply AC power to the ET, otherwise the ET may rupture. Do not use the product in atmospheres or environments that exceed product ratings. Wiring The maximum power supply voltage is VDC +%. Before turning the power ON, make sure that the power supply voltage is not more than maximum voltage. Load short-circuit protection The ET incorporates a load short-circuit protection function. If the load short-circuits, the output of the ET will be turned OFF. Then, recheck the wiring and turn on the ET again to reset the load shortcircuit protection function. The load short-circuit protection function will work if there is a current flow that is. times larger than the rated load current. When using a capacitance load, be sure that the inrush current will not exceed. times larger than the rated current. Mounting Precautions for Correct Use When mounting the Sensor, never strike it with a heavy object, such as a hammer. Doing so may reduce its watertight properties. Use M screws and flat or spring washers to secure the Sensor. (Tightening torque:. 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 A flexing resistance of Robotics Cable at approximately thousand times is far superior to that of standard cable at approximately 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. Test Contents/ conditions Result Specimen Use of E9-E Sensitivity Adjustment Unit (Dark-ON: ET-ST). Mount the Unit on the Receiver.. Set the adjuster of the Sensitivity Adjustment Unit to Max. (Before shipping: Max.). After mounting on the Sensor, adjust the optical axis and secure the Sensor.. 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.. 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 % 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. Standard cable.-mm dia.
