[. . . ] Do not connect an AC power supply to any DC model. 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. Correct Use Effects of Surrounding Metal Provide a minimum distance between the Sensor and the surrounding metal as shown in the table below. E2Q4 Design B A C Be sure to abide by the following precautions for the safe operation of the Sensor. Effects of Surrounding Metal (Unit: mm) Model E2Q4-N20 ## -M1 E2Q4-N30M ## -M1 E2Q4-N40M ## -M1 Length 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.

Mutual Interference (Unit: mm) Model E2Q4-N40M ## -M1 Length A 150 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. Therefore, it is recommended that the load be turned OFF before turning OFF the Proximity Sensor.
