WARNING This product is not designed or rated for ensuring safety of persons either directly or indirectly. Mounting Mounting Do not use it for such purposes. Mounting Directions * Make sure that the sensing side of the Sensor is parallel with the surface of each sensing object. Do not incline the Sensor towards the sensing object. Precautions for Correct Use Do not use the product in atmospheres or environments that exceed product ratings. Sensing side Surface of sensing object E3G-R/MR Designing Power Supply A power supply with full-wave rectification can be connected to the E3G-MR19(T). Wiring If the sensing object has a glossy surface, incline the Sensor by 5 to 10 as shown below, provided that the Sensor is not influenced by any background objects. The tensile strength of the cable during operation should not exceed the values shown below. Tensile strength (torque) Model E3G-R13 E3G-MR19(T) E3G-R17 * If there is a mirror-like object below the Sensor, the Sensor may not be in stable operation. Therefore, incline the Sensor or keep the Sensor a distance away from the mirror-like object as shown below. 50 N max. 10 N max. Adjusting Indicators Sensing object Mirror-like object Incident level * The following illustration indicates the operating levels of the E3G. * Set the E3G so that it will work within the stable operation range.

OFF OFF Sensing object Sensing object OFF ON ON Moving direction Moving direction Sensing object Moving direction Install the Sensor as shown in the following if each sensing object greatly differs in color or material. *If the operating level is set to the stable operation range, the E3G will operate with the highest reliability and 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 close attention to environmental changes while operating the E3G. E3G-L/ML Designing Power Supply A power supply with full-wave rectification can be connected to the E3G-ML79(T). Wiring The tensile strength of the cable during operation should not exceed the values shown below.

The size of the conduit opening is PF1/2 in accordance with JIS B0202. * Do not tighten the Terminal Protection Cover with wires pinched between the Sensor and the cover in order to maintain the waterand dust-resistive properties of the product. Designing Load Relay Contact If E3G is connected to a load with contacts that spark when the load is turned OFF (e.g., a contactor or valve), the normally-closed side may be turned ON before the normally-open side is turned OFF or vice-versa. If both normally-open output and normally-closed output are used simultaneously, apply an surge suppressor to the load. Refer to OMRON's PCB Relays Catalog (X33) for typical examples of surge suppressors. Recommended Example Wiring Connecting and Wiring Terminal protection cover Rubber bushing* 63 mm Mounting Mounting Conditions Washer* 1Tc 2Ta 3Tb 4 5 Output Clamping nut* Power supply 33 mm *Not provided with UL-compliant (-US) models. * Changing to Side-pullout Cable from Vertical-pullout Cable 1 2 E39-L129 Terminal Protection Cover Rubber bushing Washer 2 The E3G has a built-in function to protect the E3G from load shortcircuiting. If load shortcircuiting results, the output will be turned OFF. In that case, check the wiring and turn ON the E3G again so that the short-circuit protection circuit will be reset. This function will operate if the output current flow is at least 2.0 times the rated load current. If a capacitive load is connected to the E3G, make sure that the inrush current does not exceed 1.2 times the rated load current. Clamping nut * If Sensors are mounted face-to-face, make sure that no optical axes cross each other. Otherwise, mutual interference may result. * Be sure to install the Sensor carefully so that the directional angle range of the Sensor will not be directly exposed to intensive light, such as sunlight, fluorescent light, or incandescent light. * Do not strike the Photoelectric Sensor with a hammer or any other tool during the installation of the Sensor, or the Sensor will loose its water-resistive properties. * Use M4 screws to mount the Sensor. * When mounting the case, make sure that the tightening torque applied to each screw does not exceed 1.2 N*m. Water Resistance Tighten the operation cover screws and terminal block cover screws to a torque of 0.3 to 0.5 N*m in order to ensure water resistivity. 3 4 Rubber bushing* Cap* Procedure 1 2 3 4 *Provided with the E39-L129. Operation Remove the present cover. Attach the E39-L129 Terminal Protection Cover for sidepullout cable. Remove the clamping nut, washer, and rubber bushing of the E3G. These are used for the side-pullout cable.
