How to Use SN04-N NPN NO 5mm BN-5-30v Detection Distance Proximity

Mount the sensor so its sensing face is aimed at the target metal surface within 5 mm. Connect the brown wire to a 5–30 V DC positive supply, the blue wire to 0 V (ground), and the black wire to your control input or relay coil. Power on the sensor, then verify that the output switches when a metal object enters the sensing range.

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.
