I/O Circuit Diagrams

• IO-Link mode^*

  

  * When using NPN type for an IO-Link connection, use OPTEX FA’s IO-Link Master UR Series or IO-Link Master with sink support.

• NPN type

  

• PNP type

  

• Through-beam type emitter

  

• M8 connector pin assignments

  

• Connecting

  ▪1 to 4 are connector pin No.

  Notes

  ▪ When using a switching regulator for the power supply, be sure to ground the frame ground terminal.
  ▪ Because wiring sensor wires with high-voltage wires or power supply wires can result in malfunctions due to noise, which can cause damage, make sure to wire separately.
  ▪ Avoid using the transient state while the power is on (Approx. 250 ms).
  ▪ The connector direction is fixed as the drawing below when you use L-shaped connector cable. Be aware that rotation is not possible.
