Optical sensors are devices that detect minute changes or vibrations in light waves and convert them into electronic signals. The E3F2-7DB4-S is an optical sensor in the photoelectric and industrial categories that is designed for use in a variety of applications. This article will outline the application fields and working principle of this versatile sensor.

Applications

The E3F2-7DB4-S offers high functionality and sensitive response in a small package. It is designed primarily for use in industrial applications such as factory automation, process control, and monitoring applications. This sensor is also used in the medical and automotive industries as well as in robotics, where it is used to detect obstacles and monitor motion.

The E3F2-7DB4-S can be used in a range of applications, including traffic control and sensing, optical grid systems, and LED lighting. In optical grid systems, the E3F2-7DB4-S is used to detect changes in light, which are used to monitor interior position and orientation of objects within a certain area. The sensor can also be used to detect changes in light intensity for applications such as traffic control and sensing, and LED lighting.

Working Principle

The E3F2-7DB4-S utilizes a light-sensitive phototransistor to detect changes in light intensity. The phototransistor within the sensor is made up of a p-n junction, which is a junction between a p-type semiconductor and an n-type semiconductor. When a light source is placed in front of the sensor, it creates an electric field across the junction which causes a current to flow through the p-n junction. The current is then used to measure the light intensity and convert it into an electrical signal.

The E3F2-7DB4-S also utilizes a filter to block out unwanted light of varying wavelengths. This is beneficial for applications such as traffic control and sensing, where light sources of different frequencies can be used to differentiate between different signals. The filter also provides precise sensitivity and better high-frequency noise reduction for better light-detecting accuracy.

The E3F2-7DB4-S has a wide range of power supply options, offering both low power and high power modes. The low power mode is only activated when the light intensity is low, which increases efficiency and reduces power consumption. The sensor can also operate in both AC and DC power supplies, allowing it to be used in a wide range of applications.

Conclusion

The E3F2-7DB4-S optical sensor is an excellent choice for use in industrial, medical, automotive and robotics applications. Its sensitive response, wide range of power supply options, and the presence of a filter allow it to work with various light sources, making it versatile and reliable. The sensor’s working principle also ensures that the sensor will detect minute changes in light intensity and convert them into electrical signals.
