Do not impose an excessive voltage on the E2A, otherwise it may be damaged. Do not impose AC current (100 to 240 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. 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. ■ Correct Use Power OFF Designing 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 Reset Time The Proximity Sensor is ready to operate within 100 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 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. n m d dia.

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 200 m. The tractive force is 50 N. 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. 3. Check for attachment or accumulation of metal powder or dust. 4. Check for abnormal temperature conditions and other environmental conditions. 5. Check for proper lighting of indicators (for models with a set indicator.) Mounting Never disassemble or repair the Sensor. 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. Environment Do not tighten the nut with excessive force. A washer must be used with the nut. Water Resistivity Do not use the Proximity Sensor underwater, outdoors, or in the rain. Operating Environment Type M8 Torque Stainless steel type 9 N·m Brass type 4 N·m M12 30 N·m M18 70 N·m M30 180 N·m 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.
