The SN04-N Inductive Proximity Sensor is a compact and reliable detection module designed for sensing metallic objects without physical contact. Operating on 6V to 36V DC, it provides accurate detection within a range of up to 4mm.

It features an NPN normally open output, making it suitable for robotics, automation, and industrial applications. The sensor is widely used in sumo robots, object counting systems, and position detection tasks.

Equipped with a built-in LED indicator, it ensures easy status monitoring. Its IP67 protection and durable plastic body make it highly reliable in harsh environments and long-term usage.


Features:

  1. Non-Contact Metal Detection: Detects metallic objects without physical contact, reducing wear and improving long-term reliability in automation systems.
  2. NPN Normally Open Output: Provides a standard NO NPN output signal, making it easy to interface with microcontrollers and PLC systems.
  3. Wide Operating Voltage: Works efficiently across 6V to 36V DC, suitable for a variety of industrial and robotics applications.
  4. Compact Sensor Design: Small cylindrical body allows easy installation in tight spaces and embedded systems.
  5. Fast Response Time: High-speed switching ensures accurate detection in fast-moving robotic and conveyor applications.
  6. Built-in LED Indicator: Visual LED status helps in quick debugging and real-time monitoring of sensor output.
  7. IP67 Protection Rating: Highly resistant to dust and water ingress, making it suitable for harsh industrial environments.
  8. Robotics & Automation Friendly: Widely used in sumo robots, object counting systems, and position detection mechanisms.

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
