Optical sensors have become one of the most widely used sensors for many applications. Optical sensors are often used in light-based applications, such as through-beam, retro-reflective, and slot type. In this article, we will focus on slot type optical sensors, specifically the QVB11324, which is a transistor output photointerrupter.

QVB11324 Application Field

The QVB11324 photointerrupter is specifically designed for use in light-based applications that require a low-power signal transmission. It is suitable for home automation, security systems, and machine control applications. It is also ideal for use in optoelectronic switches, level sensors, motion control systems, and safety automation systems. It can be used for detecting the very small distances in robotic-related systems, such as measuring the size of objects to allow robots to move objects carefully. It can also be used in medical devices to detect the presence of objects in a certain area.

QVB11324 Working Principle

The QVB11324 slot type photointerrupter uses a phototransistor to detect changes in light levels. The sensor has an emitter (LED), a receiver (phototransistor), and a gap in between them. When a light source (such as the LED) is shone through the gap, the phototransistor detects it and sends a signal. The signal can be used to control other devices, such as a motor, or to sense when something has changed in the environment.

The QVB11324 also has an integrated shield in it which helps reduce EMI interference. This allows the sensor to be used in applications that require a high degree of accuracy and precision.

The QVB11324 has a wide operating temperature range and its response time is extremely fast (200 ns). This makes the sensor ideal for a variety of applications that require fast response times. It also has a reverse voltage protection feature, making it one of the safest slot type photointerrupters available.

Conclusion

The QVB11324 slot type photointerrupter is a powerful device for a variety of applications. It is well suited for home automation and security systems, as well as robotic and medical applications. Its low power consumption and fast response time make it an ideal choice for applications that require accurate and precise measurement. The integrated shield and reverse voltage protection also make it one of the most robust and reliable optical sensors available.
