Optical sensors, commonly known as photointerrupters, rely on the activation of a light-sensitive component in response to the presence of an object. The most popular type, the slot type, is composed of a light source and a light-sensitive detector inside a sealed housing. This article will discuss the QVB11123 slot type photointerrupter with transistor output and the application fields and working principle.

The QVB11123 optical sensor utilizes a compact slot type housing which accepts various types of light sources. The operating temperature range is between -25°C and 85°C, and its maximum voltage is 5 VDC. It features a small leakage current of less than 2.5mA, making it highly efficient and energy-saving. Moreover, its transmissive effect is very stable even under volatile ambient conditions.

This type of photointerrupter is commonly used in the fields of consumer electronics, automotive industry, and medical equipment. For consumer-level products, the sensor is well-suited for the single rotation type encoder, finger switch, and joystick for detecting movement; for automotive industry applications, QVB11123 is used as a gear position sensor or water temperature sensor; for medical equipment, the QVB11123 is often integrated in patient monitoring systems to detect heart rate movement. In addition, the optical sensor is popular among computerized machines, such as automated assembly systems, industry control systems, and printer control systems.

The working principle of the QVB11123 optical sensor is quite simple. A light source (visible light, infrared, or laser) is produced by an emitter in the housing. When a target object passes through the slot, the light from the emitter is blocked and does not reach the photo diode. This generates an output voltage, which is relayed to a transistor circuit and into a control system. The transistor circuit amplifies the output voltage signal, allowing the control system to detect even slight changes in the amount of light, ensuring accuracy and reliable performance.

In conclusion, the QVB11123 slot type photointerrupter with transistor output is a reliable and energy efficient optical sensor. With its wide temperature range and small leakage current, this optical sensor is suitable for a variety of applications in consumer electronics, automotive industry, medical equipment, and automated machines. The working principle of the QVB11123 is based on the blockage of the light source, resulting in an output voltage registered by the transistor circuit and to the control system.
