Do not use it for such purposes. Item Model E2EF-(Q)X2D1 Never use this product with an AC power supply. Otherwise, explosion may result. The following precautions must be observed to ensure safe operation. 1. Do not use the Sensor in an environment where inflammable or explosive gas is present. 2. Do not attempt to disassemble, repair, or modify any Sensors. 3. Power Supply Voltage Do not use a voltage that exceeds the rated operating voltage range. Applying a voltage that is higher than the operating voltage range may result in explosion or fire. 4. Incorrect Wiring Be sure that the power supply polarity and other wiring is correct. Incorrect wiring may cause explosion or fire. 5. Connection without a Load If the power supply is connected directly without a load, the internal elements may explode or burn. Be sure to insert a load when connecting the power supply. Precautions for Correct Use Do not use the Sensor under ambient conditions that exceed the ratings. 1. Do not use the Sensor in the following locations. (1) Outdoor locations directly subject to sunlight, rain, snow, or water droplets (2) Locations subject to atmospheres with chemical vapors, in particular solvents and acids (3) Locations subject to corrosive gas 2. The Sensor may malfunction if used near ultrasonic cleaning equipment, high-frequency equipment, transceivers, cellular phones, inverters, or other devices that generate a high-frequency electric field. Refer to the OMRON website (www.ia.omron.com/) for typical measures. 3. Laying the Sensor wiring in the same conduit or duct as highvoltage wires or power lines may result in incorrect operation and damage due to induction. Wire the Sensor using a separate conduit or independent conduit. 4. Cleaning Never use thinner or other solvents. Otherwise, the Sensor surface may be dissolved. ● Design Influence of Surrounding Metal E2EF-(Q)X12D1 d D m n Iron 0 8 0 8 30 Aluminum 10 50 10 8 50 Iron 0 12 0 12 40 Aluminum 16 70 16 12 70 Iron 0 18 0 28 60 Aluminum 16 80 16 28 80 Iron 0 30 0 48 100 Aluminum 24 120 24 48 120 Note: The influence from other non-magnetic surrounding metals is nearly the same as that from aluminum.
