Optical sensors are used to detect and measure the light emitted, reflected or transmitted from an object or material. Phototransistors are used to convert light energy into electrical energy. The QSE112 is a dedicated phototransistor sensor designed for precision detection in harsh industrial environments. It offers fast response times and high sensitivity in combination with superior signal stability.

The QSE112 is based on single-element, internally isolated phototransistors. Its innovative design ensures high isolation from environmental disturbances, making it ideal for application in high energy and electrical noise environments. The phototransistor is integrated with a built-in voltage-controlled amplifier that can be used to adjust the sensitivity of the device. The device is available in single, dual, and four-channel configurations, allowing for wide-ranging applications.

The wide dynamic range of electron gain makes the QSE112 an ideal choice for applications requiring fine-tuned response time. The device has an independently adjustable voltage sensitivity range from 0 to 100V and a wide gain range of up to 1000:1. This allows for precise control over the signal response, ensuring that the device can be used in applications such as light curtains, photoelectric barriers, and machine vision, where accuracy and reliability are of paramount importance.

In addition to these features, the QSE112 offers excellent signal stability and accuracy. The precise control over gain and response times ensures that the device is suitable for use in highly dynamic applications. This makes the QSE112 an ideal choice for applications in the automotive, medical, and industrial sectors. Such applications may include optical navigation, safety control, and medical imaging, among others.

The working principle of the QSE112 is quite simple. Light energy is supplied to the device in an infrared beam. The phototransistor converts this light energy into an electrical signal, which is then amplified by the voltage-controlled amplifier. This amplified signal is used to control the output of the device. The output is used to monitor and control various industrial processes, such as machine vision, motion control and automation, or industrial safety systems.

The QSE112 provides fast response times, high gains, and excellent signal stability. This makes it an ideal choice for applications requiring high levels of accuracy and reliability. Its robust design coupled with its low power consumption makes it well suited to industrial and medical applications. As such, the QSE112 is a versatile and reliable optical sensing device for a wide range of applications.
