Line Sensor Notes

• Manufacturer: Allen-Bradley / Rockwell Automation

• Part Number: 42EF-D1MNAK-a

• Wiring:
  • brown wire to power
  • blue wire to ground
  • white and black wires are outputs with load

• LED indicators:
  • Green: indicates sensor On/Off
  • Yellow: indicates target found if on, not found it off
  • Orange: indicates strong target (margin > 2.5) found if on, weak target (margin < 2.5) if off

Outputs

	Without Load		With Load (~2kOhm)
LEDs:	White Wire	Black Wire	White Wire	Black Wire
Both Off	0.7V	1.0V	0.9V	11V
Yellow On, Orange Off	2.4V	0.8V	11.8V	0.7V
Both On	2.8V	0.8V	11.0V	0.7V

Conclusion: Orange LED can only be used for calibration, not for output.
