If power supplies are connected to the Proximity Sensor and load respectively, be sure to supply power to the Proximity Sensor before supplying power to the load. Power OFF The Proximity Sensor may output a pulse signal when it is turned off. You must turn off the load 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 Metal Coating The sensing distances of the Proximity Sensor vary with the metal coating on sensing objects. J WIRING High-tension Lines Wiring through Metal Conduit If there is a 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 malfunctioning. Cable Tractive Force Do not pull cable with the tractive forces exceeding the following. Diameter Tractive force 4 mm dia. max. 30 N max. 4 mm dia. min. 50 N max. J MOUNTING The Proximity Sensor must not be subjected to excessive shock with a hammer when it is installed, or the Proximity Sensor may be damaged or lose its water-resistance. J ENVIRONMENT Water Resistance 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 resistant, 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). 16 E2E 3-Wire DC E2E 3-Wire DC NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS.
