4-20 mA Output

The 4-20 mA output distance sensor you described is a robust and reliable industrial-grade device designed for precise distance measurement in automation and control applications. Below is a breakdown of its key features and specifications:

Typical Applications:

✔ Industrial Automation (position monitoring, object detection)
✔ Process Control (liquid level, thickness measurement)
✔ Machine Safety & Feedback Systems
✔ Conveyor Belt & Robotic Guidance

Advantages of 4-20 mA Output:

• No signal loss over long distances (unlike voltage signals).

• Works in electrically noisy environments (factories, motors nearby).

• Simple 2-wire connection (power + signal in same loop).

Key Features:

1. Linear 4-20 mA Current Output

   • Proportional to the distance of the target (8 mm to 15 mm range).

   • 4 mA = Minimum distance (e.g., 8 mm).

   • 20 mA = Maximum distance (e.g., 15 mm).

2. Industrial Compatibility

   • Works seamlessly with PLCs, SCADA systems, and data loggers.

   • Immune to voltage drops & electrical noise, making it ideal for long cable runs.

3. High Reliability & Durability

   • IP68 protection (dustproof & waterproof).

   • Chrome-plated brass housing for corrosion resistance.

   • Short-circuit & reverse polarity protection for safety.

4. Fast Response & Accuracy

   • Switching frequency: 200 Hz (suitable for dynamic applications).

   • Repeatability & hysteresis: 5-10% of sensing distance.

5. Easy Installation & Monitoring

   • LED status indicator for visual feedback.

   • Non-flush mounting (allows side sensing).
