🚀 Why Choose the E18-D30NA Sensor?

🌟 Precision Detection, Simplified Setup

This infrared photoelectric sensor uses diffuse reflection technology, meaning it detects objects without the need for a separate reflector. Simply mount, power up, and adjust the detection range — ideal for tight spaces or simplified installations.

🛠️ Easy Installation and Integration

Its M18 threaded design makes mounting quick and secure, while the pre-wired connection and standard voltage range ensure compatibility with most control systems. It's perfect for both industrial engineers and electronics hobbyists.

⚙️ Versatile Applications

• Conveyor belt object detection

• Automated sorting/counting systems

• Smart robotics and obstacle avoidance

• DIY projects with Arduino or Raspberry Pi

• Packaging lines, bottle counters, and inspection machines

💡 Application Examples

🔍 How to Use & Optimize

1. Mount securely to a bracket, robot frame, or panel.

2. Adjust detection distance using the potentiometer (3–30 cm).

3. Wire using the 3-wire system:

   • Brown = +V (6–36V DC)

   • Blue = GND

   • Black = Signal (NPN NO output)

4. Use shielded cables in noisy environments for interference protection.

5. Keep the lens clean to ensure accurate infrared detection.

6. Monitor the LED indicator on the sensor for real-time detection feedback.

🌐 Compatibility

• ✅ Arduino / Raspberry Pi

• ✅ PLCs (Programmable Logic Controllers)

• ✅ Relay modules and industrial controllers

• ✅ 12V / 24V automation systems

• ⚠️ Note: For 5V-only microcontrollers, use a level shifter or 5V regulator.

🛡️ Industrial-Grade Durability

• IP65 rated: Protected from dust and water splashes

• Shock and vibration resistant: Withstands factory environments

• ABS housing: Tough and long-lasting

• Wide temperature range: Operates in challenging indoor/outdoor conditions
