WARNING This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. Precautions for Correct Use Do not use this product under ambient conditions that exceed the ratings. AND/OR Connections Design Influence of Surrounding Metal Error pulses and leakage current may prevent application in AND or OR circuits. Always confirm operation in advance to confirm if there are any problems in operation. When mounting the Sensor within a metal panel, ensure that the clearances given in the following table are maintained. Failure to maintain these distances may cause deterioration in the performance of the Sensor. Mutual Interference When installing Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained. A l B A n m d dia.

(The meanings of the symbols are given below.) 1. The ON voltage of the PLC and the residual voltage of the Proximity Sensor must satisfy the following. VON VCC - VR 2. The OFF current of the PLC and the leakage current of the Proximity Sensor must satisfy the following. IOFF Ileak (If the OFF current is not listed in the specifications, take it to be 1.3 mA.) 3. The ON current of the PLC and the control output (IOUT) of the Proximity Sensor must satisfy the following. IOUT (min.) ION IOUT (max.) The ON current of the PLC will vary, however, with the power supply voltage and the input impedance, as shown in the following equation. ION = (VCC - VR - VPC)/RIN VON: ION: IOFF: RIN: VPC: VR : ON voltage of PLC (14.4 V) ON current of PLC (typ. 7 mA) OFF current of PLC (1.3 mA) Input impedance of PLC (3 k) Internal residual voltage of PLC (4 V) Output residual voltage of Proximity Sensor (5 V) Ileak: Leakage current of Proximity Sensor (0.8 mA) IOUT: Control output of Proximity Sensor (3 to 100 mA) VCC: Power supply voltage (PLC: 20.4 to 26.4 V) Values in parentheses apply to the following PLC model and Proximity Sensor model. PLC: C200H-ID212 Sensor: E2EM-X8X1 Example In this example, the above conditions are checked when the PLC Unit is the C200H-ID212, the Proximity Sensor is the E2EM-X8X1, and the power supply voltage is 24 V. 1. VON (14.4 V) VCC (20.4 V) - VR (5 V) = 15.4 V: OK 2. IOFF (1.3 mA) Ileak (0.8 mA): OK 3. ION = [VCC (20.4 V) - VR (5 V) - VPC (4 V)]/RIN (3 k) = Approx. 3.8 mA Therefore, IOUT(min.) (3 mA) ION (3.8 mA): OK 6 E2EM Mounting Tightening Force Note: 1. The allowable tightening strength depends on the distance from the edge of the head, as shown in the following table. (A is the distance from the edge of the head. B includes the nut on the head side. If the edge of the nut is in part A, the tightening torque for part A applies instead.) 2. The following strengths assume washers are being used. Do not tighten the nut with excessive force. A washer must be used with the nut.
