?Introduction to QVB11134 The QVB11134 is a slot type photointerrupter with a transistor output. The device helps to detect the passing of an object by sensing changes in light between an emitter and a detector. It features a slim profile allowing for excellent stability, better sensor performance and a wide range of operating temperatures while providing a longer service life. Features of QVB11134 The QVB11134 has several impressive features. These features make it suitable for embedded applications: • Fast response time of 1 ms, making it suitable for various applications • High input/output speed of up to 10 mA • High sensitivity between 2 – 4 mA • Low power consumption of 2 mW • Maximum operating temperature range up to 70℃ • Transistor output makes it easy to be integrated with other types of technology • Compact and slim design for better stability and performance Applications of QVB11134 The QVB11134 is designed to meet a variety of applications, from industrial automation and robotics, to office automation and home applications. It can be used as a motion detector, light switch, counter, or other type of sensor to detect the passage or presence of an object. The sensor can be used for detecting the position of an object or the entrance/exit of an object, to control the start and/or stop of machinery. In industrial automation, it can act as a counter for continuous production lines, as well as in conveyor systems for accurate product positioning. In addition to factory automation, the QVB11134 can be used in office automation applications for copy machines, fax machines and printers. It can also be used for other types of object detection, such as in automatic doors, automatic taps or as a sensor for automatic street lights. Working Principle of QVB11134 The QVB11134 is an infrared photointerrupter which operates on the principle of an optical gate. This device includes an infrared LED in the emitter unit which emits light towards the detector. When an object passes between the two units, the emitted light is blocked. This blockage causes a signal to be sent to the output transistor, which acts as a switch. The response time of the device depends on the amount of light that is blocked by the object. The sensitivity of the device is adjusted by adjusting the amount of light that is blocked or received between the emitter and detector. This adjustment can be made by changing the distance between the two units, or by reducing the quantity of the emitted light. Conclusion The QVB11134 is an effective way to detect the presence or passing of an object. It is an advanced optical gate that features a slim profile, fast response time, high input/output speed, and can be used in a variety of different applications. The device has a long operating life and is capable of operating within a range of temperatures. With its high sensitivity and low power consumption, the QVB11134 is the perfect sensor for embedded applications.
