Features
This economical, universal Digital Fiber Optic Sensor perfectly replaces the Japanese E3X-NA11 and E3X-NA41 analog fiber optic amplifiers. It's a digitally upgraded basic model, compatible with most standard fiber optic probes.
Features include:
• Low-power digital circuitry, reducing workshop electricity costs over long-term operation, and compatibility with 24V DC automation power supply;
• One-button digital automatic teaching, eliminating the need for repeated knob adjustments, completing threshold calibration in 3 seconds, making it easy for beginners;
• Built-in digital dynamic light compensation chip, automatically compensating for interference from dust, strong ambient light, and workpiece reflection fluctuations;
• 5 adjustable digital response speeds, with digitally locked hysteresis values to prevent signal jitter and erroneous output;
• Dual independent red and green digital displays, synchronously displaying received light intensity and trigger thresholds in real time, providing clear and easy-to-understand parameters.
Advantages
Compared to traditional analog fiber optic sensors, Garantta's digital fiber optic sensing system boasts unique core digital advantages:
1. A fully digital, anti-electromagnetic interference architecture converts optical signals into digital signals for instant computation. Electromagnetic radiation from servo motors, frequency converters, and welding equipment will not interfere with the detection data, ensuring stable operation in semiconductor and new energy high-voltage production lines.
2. Intelligent digital real-time compensation: The built-in chip continuously collects data on ambient light, lens dust accumulation, and workpiece reflection changes, dynamically correcting thresholds digitally without requiring frequent recalibration during production line downtime.
3. Traceable digital data: Light intensity, trigger thresholds, and fault codes are all output as digital signals, compatible with MES systems for end-to-end uploading and archiving of production and testing data.
4. Ultra-fine scene adaptation: High-precision digital sampling at microsecond-level digital sampling frequencies allows for stable identification of minute features such as chip pins, micro springs, and liquid levels in medicine bottles, with detection accuracy more than 3 times better than analog fiber optics.
5. Safe, contactless digital detection: The fiber optic probe contains no electronic components, is high-temperature resistant, explosion-proof, and corrosion-resistant. The amplifier unit can be installed independently away from high-temperature and corrosive areas, making it suitable for chemical and high-temperature molding production lines.
