Optical Sensors - Photo Detectors - Logic Output - QSE156 application field and working principle

The QSE156 is a photo detector designed with Japanese Sanyo technology that integrates logic output and optical sensors. It is widely employed in a variety of applications, such as optical switches, digital encoders, mechanical actuators, and motion sensors. The electrical characteristics, small size, and high speed response of QSE156 effectively contribute to high efficiency operation.

The basic operation of the QSE156 is based on a photo detector assembled onto an IC. The photo detector consists of an active pixel array, a light blocking filter, and a photodiode. This array is connected to an amplifier, which provides amplification for the signal from the photodiode. The amplifier is then connected to a logic circuit, which processes the signal from the amplifier and provides a logic output signal. This output signal can then be used to control or initiate a specific action.

The QSE156 is designed to operate in a variety of illumination ranges, such as ambient room light, due to its ability to detect light in a wide range of wavelengths. Additionally, the QSE156 has a large dynamic range, making it suitable for detecting both large and small light levels. For example, the QSE156 could be used to switch between a sheet of dark material and a fluorescent light. In this case, the dark material would switch on the illumination from the light, while the light level will be maintained using the photodiode.

In addition to its use as an optical switch, the QSE156 can be used as a digital encoder for a wide range of applications. The digital encoder functions by measuring the amount of light that is blocked or reflected by a surface, and converting this into digital values. This information is then used to control various tasks, such as automated tasks, security functions, and door access control systems. The QSE156 is also compatible with most digital communication protocols, such as RS-232, RS-485, and USB.

The QSE156 is also widely employed in the field of mechanical actuators. Its wide range of operating speed and high response time makes it suitable for controlling a wide variety of mechanical tasks. For example, the QSE156 can be used to control the exact speed and positioning of servomotors, which are used in robotic arms and other automated systems. Additionally, the QSE156 can also be used in motion sensors, such as linear actuators. In these applications, the logic output signal of the QSE156 is used to open or close the circuit, and the power to the motor is then regulated.

The QSE156 is an innovative and reliable photo detector device that features a wide range of applications in many different fields. Its ability to detect light in many different wavelengths, and its fast responding logic output, make it suitable for use in optical switches, digital encoders, mechanical actuators, and motion sensors. Its small size and low power consumption also make it suitable for a variety of applications.
