Frequently Asked Questions
Q: What is the detection range of the E3F M18 photoelectric sensor switch?
A: The E3F Series M18 photoelectric sensor switch offers an adjustable detection range of 3 to 30 cm, making it versatile for detecting objects at varying distances in automation and industrial applications.
Q: What is the difference between NPN and PNP output on this photoelectric sensor?
A: NPN output (sinking) connects the load between the output and the positive supply, while PNP output (sourcing) connects the load between the output and the negative supply. Choose the output type that matches your controller or PLC input requirements. Both versions operate on 6–36V DC.
Q: Is this sensor compatible with Arduino or Raspberry Pi projects?
A: Yes, the E3F photoelectric sensor can be used with microcontrollers like Arduino or Raspberry Pi. For 5V systems, use a voltage divider or logic-level shifter on the signal line, and ensure your power supply falls within the 6–36V DC operating range for the sensor itself.
Q: What does M18 mean for this proximity sensor?
A: M18 refers to the threaded barrel diameter of 18 mm. This is a standard industrial thread size that allows the sensor to be easily mounted using standard M18 mounting brackets, nuts, or panel cutouts.
