Connecting IO-Link Sensors

Sensors connect to the numbered IO-Link ports on the master block with M12 cable. Set the block up first — see Master Block Setup — so you can confirm each sensor as you wire it in.

Step 1: Plan Sensor Placement​

  1. Identify measurement points on your equipment
  2. Determine appropriate sensor types for each point
  3. Plan cable routing from sensors to master block

Common Use Cases:

ApplicationSensor TypeExample IFM Models
Hydraulic PressurePressure SensorPN, PT series
Coolant TemperatureTemperature SensorTN, TA series
Air Flow RateFlow SensorSM, SD series
Tool VibrationVibration SensorVSE, VSP series
Part PositionDistance SensorO1D, O5D series
Coolant LevelLevel SensorLR, LK series
Spindle TemperatureTemperature SensorTN series

Step 2: Mount Sensors​

  1. Install sensors at measurement points
  2. Follow manufacturer's installation guidelines
  3. Ensure proper orientation (especially for flow sensors)
  4. Verify sensor is within operating range

Step 3: Connect M12 Cables​

  1. Use appropriate M12 cables (4-pin or 5-pin depending on sensor)
  2. Connect sensor M12 connector to cable
  3. Route cable to master block location
  4. Connect cable to master block port

Step 4: Label Connections​

Document each connection:

  • Port number
  • Sensor type
  • Measurement location
  • Cable routing
