Reflective optical sensors with analog output are optoelectronic devices that detect the presence, distance, or reflectivity of objects by emitting light and measuring the intensity of reflected light. Unlike digital sensors, analog output sensors provide continuous voltage/current signals proportional to the detected light intensity, enabling precise measurement of position, color, or material properties. They play critical roles in automation, robotics, and precision measurement systems where real-time analog data is required.
| Type | Functional Features | Application Examples |
|---|---|---|
| Infrared Reflective Sensors | Use IR LEDs (850-950nm), insensitive to ambient light | Industrial object detection, paper jam sensors in printers |
| Visible Light Sensors | Use green/red LEDs, sensitive to surface color variations | Color recognition in packaging, liquid level monitoring |
| High-Precision Analog Sensors | 0-5V/4-20mA outputs with 0.5% linearity | Semiconductor wafer alignment, precision displacement measurement |
Typical components include: - Light Source: GaAlAs LED (5-50mA forward current) - Receiver: PIN photodiode with built-in amplifier - Optical System: Collimating lens ( 2 beam angle) - Signal Processor: Transimpedance amplifier with temperature compensation - Enclosure: IP67-rated housing with anti-reflective coating
