[. . . ] (at 500 VDC) between current carry parts and case 10 to 55 Hz, 1. 5 mm double amplitude for 2 hours each in X, Y, and Z directions Destruction: 1, 000 m/s2 for 10 times each in X, Y, and Z directions IEC IP68 *3 Pre-wired models (standard length 2 m) Approx. The response frequencies are average values measured on condition that the distance between each sensing object is twice as large as the size of the sensing object and the sensing distance set is half of the maximum sensing distance. Short circuit protection types are available. OMRON test method Conditions: Less than 10 m natural state under water (1) It is not flooded underwater with two atmospheric pressure for 1 hour. [. . . ] 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). Refer to the following to calculate the bleeder resistance and the allowable power of the bleeder resistor. R VS/(10 ­ I) (k) P > VS2/R (mW) P:The allowable power of the bleeder resistor. (The actual power capacity of the bleeder resistor must be at least a few times as large as the allowable power of the bleeder resistor. ) I:Load current (mA) The following resistors are recommended. 100 VAC (supply voltage): A resistor with a resistance of 10 k maximum and an allowable power of 3 W minimum 200 VAC (supply voltage): A resistor with a resistance of 20 k maximum and an allowable power of 10 W minimum If these resistors generate excessive heat, use a resistor with a resistance of 10 k maximum and an allowable power of 5 W minimum at 100 VAC and a resistor with a resistance of 20 k maximum and an allowable power of 10 W minimum at 200 VAC instead. E2E-@Y/E2F-@Y 9 Precautions for AC 2-wire Proximity Sensors in Operation Connection Model AC 2-wire Connection type AND (serial connection) Method Description If 100 or 200 VAC is imposed on the Proximity Sensors, VL (i. e. , the voltage imposed on the load) will be obtained from the following. of Proximity Sensors) (V) Incorrect Load Correct Load Therefore, if VL is lower than the load operating voltage, the load will not operate. A maximum of three Proximity Sensors can be connected in series provided that the supply voltage is 100 V minimum. Load Vs × 100 V OR (parallel connection) Incorrect A Load In principle, more than two Proximity Sensors cannot be connected in parallel. Provided that Proximity Sensor A does not operate with Proximity Sensor B simultaneously and there is no need to keep the load operating continuously, the Proximity Sensors can be connected in parallel. In this case, however, due to the total leakage current of the Proximity Sensors, the load may not reset properly. VAC power supply VS B Correct A B Load It is not possible to keep the load operating continuously with Proximity Sensors A and B in simultaneous operation to sense sensing objects due to the following reason. When Proximity Sensor A is ON, the voltage imposed on Proximity Sensor A will drop to approximately 10 V and the load current flows into Proximity Sensor A, and when one of the sensing objects is close to Proximity Sensor B, Proximity Sensor B will not operate because the voltage imposed on Proximity Sensor B is 10 V, which is too low. When Proximity Sensor A is OFF, the voltage imposed on Proximity Sensor B will reach the supply voltage and Proximity Sensor B will be ON. Then, Proximity Sensor A as well as Proximity Sensor B will be OFF for approximately 10 ms, which resets the load for an instant. To prevent the instantaneous resetting of the load, use a relay as shown on the left. 10 Cylindrical Inductive Sensor for AC Power Supply Dimensions E2F-X1R5Y CAD file E2F_03 E2F-X2Y CAD file E2F_05 15 dia.
