Frequently Asked Questions
Q: What is the difference between NPN and PNP output on the E3F-DS10 photoelectric sensor?
A: NPN (sinking) output pulls the signal line LOW when an object is detected, while PNP (sourcing) output pulls the signal line HIGH. Choose NPN for most microcontroller and PLC setups that use a common ground reference, and PNP when your control circuit requires a high-side switch. The E3F-DS10 series offers both variants so you can match your exact wiring needs.
Q: Can the E3F-DS10 sensor run on both AC and DC power?
A: Yes. The E3F-DS10 supports a wide dual-voltage range — 6–36V DC for low-voltage electronics and microcontroller projects, and 90–250V AC for direct integration into mains-powered industrial panels. Always check the specific model suffix (C4, P1, P2, Y1, Y2) for the exact voltage and output configuration before wiring.
Q: What does "diffuse reflection" detection mode mean?
A: In diffuse reflection mode, the sensor's transmitter emits an infrared beam and the receiver detects light bounced back from the target object itself — no separate reflector is needed. The E3F-DS10 triggers when a target enters within its 10 cm sensing range, making it ideal for detecting objects of varying surfaces in a compact setup.
