Generic SN04-N NPN NO Inductive Proximity Sensor - 5mm Detection, 1.5m Cable
The SN04-N is an NPN normally open (NO) inductive proximity sensor designed for non-contact detection of metallic objects within a 5mm range. Operating from a 10-30V DC supply, it features a 1.5-meter cable and is compatible with industrial PLCs and automation systems.
Features
- NPN Normally Open (NO) output for direct PLC and microcontroller interfacing.
- 5mm nominal detection distance for ferrous and non-ferrous metals.
- Wide 10-30V DC operating voltage range with reverse polarity and short-circuit protection.
- High 500Hz switching frequency for fast-response automation applications.
- IP67-rated ABS housing for dustproof and waterproof operation in industrial environments.

The SN04-N operates on the inductive sensing principle, generating an electromagnetic field to detect the presence of metallic targets without physical contact. Its internal oscillator and signal conditioning circuitry provide a stable NPN open-collector output that sinks current to ground when an object is detected, making it suitable for direct connection to programmable logic controllers (PLCs) and 24V industrial control systems.
Encased in an ABS plastic housing with an IP67 protection rating, the sensor is resistant to dust, water, and oil ingress, ensuring reliable performance in challenging factory floor conditions. A built-in red LED provides visual feedback for power status and target detection, aiding in installation and troubleshooting.
