1 Cylindrical Proximity Sensor E2A Safe Mounting with Greater Sensing Distance Ensures a sensing distance approximately 1. to 2 times larger than that of any conventional OMRON Sensor. Problems such as the collision of workpieces are eliminated. Full range of standard sizes (M8, M12, M18 and M; both long and short barrels) Modular construction simplifies customization.

14 Precautions Safety Precautions Power Supply Do not impose an excessive voltage on the E2A, otherwise it may be damaged. Do not impose AC current ( to 2 VAC) on any DC model, otherwise it may be damaged. Load Short-circuit Do not short-circuit the load, or the E2A may be damaged. The E2A s short-circuit protection function will be valid if the polarity of the supply voltage imposed is correct and within the rated voltage range. Correct Use Designing Power Reset Time The Proximity Sensor is ready to operate within ms after power is supplied. If power supplies are connected to the Proximity Sensor and load respectively, be sure to supply power to the Proximity Sensor before supplying power to the load. Effects of Surrounding Metal When mounting the E2A within a metal panel, ensure that the clearances given in the following table are maintained. l Wiring Be sure to wire the E2A and load correctly, otherwise it may be damaged. Connection with No Load Be sure to insert loads when wiring. Make sure to connect a proper load to the E2A in operation, otherwise it may damage internal elements. Do not expose the product to flammable or explosive gases. Do not disassemble, repair, or modify the product. Power OFF The Proximity Sensor may output a pulse signal when it is turned OFF. Therefore, it is recommended that the load be turned OFF before turning OFF the Proximity Sensor. Power Supply Transformer When using a DC power supply, make sure that the DC power supply has an insulated transformer. Do not use a DC power supply with an auto-transformer. Mutual Interference When installing two or more Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained.

15 Wiring High-tension Lines Wiring through Metal Conduit: If there is a power or high-tension line near the cable of the Proximity Sensor, wire the cable through an independent metal conduit to prevent against Proximity Sensor damage or malfunctioning. Cable Extension Standard cable length is less than 2 m. The tractive force is N. Mounting The Proximity Sensor must not be subjected to excessive shock with a hammer when it is installed, otherwise the Proximity Sensor may be damaged or lose its water-resistivity. Do not tighten the nut with excessive force. A washer must be used with the nut. Maintenance and Inspection Periodically perform the following checks to ensure stable operation of the Proximity Sensor over a long period of time. 1. Check for mounting position, dislocation, looseness, or distortion of the Proximity Sensor and sensing objects. 2. Check for loose wiring and connections, improper contacts, and line breakage.. Check for attachment or accumulation of metal powder or dust.. Check for abnormal temperature conditions and other environmental conditions.. Check for proper lighting of indicators (for models with a set indicator.) Never disassemble or repair the Sensor. Environment Water Resistivity Do not use the Proximity Sensor underwater, outdoors, or in the rain. M8 M12 M18 M Type Torque Stainless steel type 9 Nm type Nm Nm 7 Nm 18 Nm Operating Environment Be sure to use the Proximity Sensor within its operating ambient temperature range and do not use the Proximity Sensor outdoors so that its reliability and life expectancy can be maintained. Although the Proximity Sensor is water resistive, a cover to protect the Proximity Sensor from water or water-soluble machining oil is recommended so that its reliability and life expectancy can be maintained. Do not use the Proximity Sensor in an environment with chemical gas (e.g., strong alkaline or acid gasses including nitric, chromic, and concentrated sulfuric acid gases). Inrush Current A load that has a large inrush current (e.g., a lamp or motor) will damage the Proximity Sensor, in which case connect the load to the Proximity Sensor through a relay.
