OPB730

Optical Sensors - Reflective - Analog Output

The OPB730 optical sensor is a non-contact sensing device used to detect objects with integrated, visible, red light emitting diode (LED) and phototransistor (photosensitive transistor). It is a proximity and position sensing device well-suited for many different applications, including detection of changes in ambient light, movement of objects and distance measurements between two points. This article will provide an overview of the application field and working principle of the OPB730.

Application Field

The OPB730 optical sensor can be used to detect objects accurately and reliably, even when there is a lot of ambient light present. It is suitable for a wide variety of applications, ranging from factory automation and industrial process control to robotics and home automation. Its integrated LED and phototransistor make it suitable for use in sensing and detection applications.

The OPB730 can be used in medical applications such as in the detection of drugs or contaminants in pharmaceutical products, or in inspection of various medical implants and components.

This optical sensor is also suitable for use in consumer electronics such as cell phones, gaming consoles, and camera modules. It can detect objects or events for a variety of purposes, including Augmented Reality (AR) applications, presence monitoring, and obstruction detection.

Working Principle

The working principle of the OPB730 optical sensor is based on the use of an integrated LED and phototransistor. The LED emits a beam of light and the phototransistor detects any reflecting light, sending it to a signal processing circuit. When an object is detected, the intensity of the reflected light changes and the processor will detect this change, allowing the sensor to accurately detect the object.

The OPB730 utilizes a voltage output analog signal in order to measure and interpret the change in light intensity. This allows for a maximum detection range of up to 10cm, depending on the specific model and ambient lighting conditions. With its precise detection range and voltage output, the OPB730 can accurately measure the distance and presence of objects.

Conclusion

The OPB730 optical sensor is an efficient and versatile device containing an LED and phototransistor. It is suitable for a wide range of detection and proximity sensing applications, including industrial process control, medical inspection, and consumer electronics. This sensor utilizes an voltage output analog signal in order to accurately measure the distance and presence of objects, with a maximum detection range of up 10cm.
