[. . . ] If the load and Sensor are connected to independent power supplies respectively, be sure to turn ON the Sensor before supplying power to the load. 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. Sensing Object The sensing distance of the Proximity Sensor vary with the metal coating on sensing objects. Wiring Power Supply Voltage and Output Load Power Supply Voltage Make sure that the power supply to the Sensor is within the rated voltage range. If a voltage exceeding the rated voltage range is supplied to the Sensor, it may explode or burn. Load Short-circuiting Do not short-circuit the load, otherwise the Sensor may be damaged. Connection without Load Do not connect the power supply to the Sensor with no load connected, otherwise the internal elements may explode or burn. E2Q5 Wiring Operating Environment Do not use the Sensor in locations with explosive or flammable gas. High-tension cables Wiring through Metal Conduit: If there is 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 malfunction. Correct Use Design Effects of Surrounding Metal Provide a minimum distance between the Sensor and the surrounding metal as shown in the table below.

Environment Water Resistivity Do not use the Proximity Sensor underwater, outdoors or in the rain. 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 Snesor, in this case connect the load to the Proximity Sensor through a Relay Maintenance and Inspection Periodically perform the following checks to ensure stable operation of the Proximity Sensor over a long period of time.
