Frequently Asked Questions
What wiring connections are required for the SN04-N sensor?
Connect the brown wire to 5–30 V DC positive, the blue wire to ground (0 V), and the black wire to your control input or load. When a metal target is detected within 5 mm, the NPN output switches on.
Can the SN04-N detect stainless steel or aluminum?
The SN04-N offers optimal detection for ferrous metals like iron and steel at the full 5 mm range. Non‐ferrous materials such as stainless steel or aluminum will be detected at a slightly reduced distance.
Is the sensor suitable for outdoor or wet environments?
Yes, the SN04-N features an IP67-rated enclosure, making it dust‐tight and protected against temporary immersion in water, ensuring reliable operation in harsh or wet conditions.
