● Design
Influence of Surrounding Metal
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.
Influence of Surrounding Metal
Connecting a DC 2-wire Proximity Sensor to a PLC (Programmable Controller)
Required Conditions
Connection to a PLC is possible if the specifications of the PLC and the Proximity Sensor satisfy
the following conditions. (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
2. The OFF current of the PLC and the leakage current of the Proximity Sensor must satisfy the
3. The ON current of the PLC and the control output (I
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.

AND/OR Connections
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.
Mutual Interference
When installing Sensors face-to-face or side-by-side, ensure that the
minimum distances given in the following table are maintained.
