Safety PrecautionsTo ensure safe operation, be sure to read and follow the Instruction Manual provided with the Sensor.

This product is not designed or rated for ensuring safety of persons either directly or indirectly.Do not use it for such purposes.

Do not use the product with a voltage or current that exceeds the rated range.Applying a voltage or current that is higher than the rated range may result in explosion or fire.

Do not miswire such as the polarity of the power supply voltage.Otherwise the product may be damaged or it may burn.

This product does not resist water. Do not use the product in places where water or oil may be sprayed onto the product.

• Do not use the product in atmospheres or environments that exceed product ratings.

• When using the sensor on moving parts, secure the pull out portion of the cord so that it is not subjected to direct stress.

• Do not perform cord wiring when power supply voltage is applied. Doing so may result in breakage.

• Dispose of this product as industrial waste.
