D-42 Inductive Sensors Safety Precautions Precautions for Safe Use WARNING This product is not designed or rated for ensuring safety of persons. Do not it for such purposes. Wiring Be sure to wire the E2A3 and load correctly, otherwise it may be damaged. Connection with No Load Be sure to insert a load when wiring. [. . . ] Do not tighten the nut with excessive force. A washer must be used with the nut. Environment Water Resistivity The Proximity Sensors are tested intensively on water resistance, but to ensure maximum performance and life expectancy, avoid immersion in water and provide protection from rain or snow. Operating Environment Store and operate the Proximity Sensor only within the given specifications. M8 M12 M18 M30 Type Stainless Steel Model Brass Model Torque 9 N·m --20 N·m 60 N·m 150 N·m Inrush Current A load that has a large inrush current (e. g. , a lamp or motor) will damage the Proximity Sensor. Connect the load to the Proximity Sensor through a relay. <SUITABILITY FOR USE> OMRON shall not be responsible for conformity with any standards, codes, or regulations that apply to the combination of the products in the customer's application or use of the products.
