[. . . ] If AC power (100 VAC or more) is supplied to the sensor, it may explode or burn. Do not use the Sensor in locations with explosive or flammable gas.
Effects of Surrounding Metal Provide a minimum distance between the Sensor and the surrounding metal as shown in the table below.

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.

Maintenance and Inspection
Periodically perform the following checks to ensure stable operation of the Proximity Sensor over a long period of time. · Check for mounting position, dislocation, looseness or distortion of the Proximity Sensor and sensing objects. · 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. Never disassemble or repair the Sensor.
Power Reset Time The Sensor is ready to operate within 300 ms after the Sensor is turned ON. 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. [. . . ] 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
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.
