Optical Sensors have become increasingly important in industries such as agriculture, aerospace, automotive, manufacturing, medical, and many more. One type of optical sensor specifically is a Photointerrupter. Photointerrupters use an optical beam to detect, measure, or count objects. These devices are generally composed of two parts, an emitter and a detector, with a gap between them. The most common type of Photointerrupter is a slot-type, such as the QVB11133, which is equipped with a Transistor Output.

QVB11133

The QVB11133 Photointerrupter is a slot-type Photointerrupter with Transistor Output from the QM1D Series manufactured by Panasonic. The QVB11133 Photointerrupter features a wide gap distance for reliable operation even when dealing with long objects. Additionally, the sensor has a wide operating temperature range, from -40℃ to 85℃, a fast response time, and high isolation voltage. The entire unit is constructed from a fire resisitant engineering plastic housing making it suitable for use in safety and explosion-proof applications. The PCB side of the unit has two metal pins, which can be bent at a 90° angle to easily mount into a circuit board.

Application Field

The QVB11133 Photointerrupter is used in a variety of applications, most commonly in interior and exterior lighting, industrial drawing and cutting machines, robotic arms, conveyors,material handling, and food processing. It can also be used in more sensitive applications such as medical equipment, electronic locks, anti-theft systems, 3D printers, and more.

Working Principle

The basic operating principle of the QVB11133 Photointerrupter can be understood by examining the parts of the system. The emitter of the Photointerrupter is typically an infrared LED emitter, which will emit a beam towards the object to be detected. This beam is then interrupted when the object passes within range of the optical gap. The receiver is typically a photodiode-type receiver, which then sends a signal to the Transistor output. When the beam is interrupted, the signal is sent, activating the Transistor output and then activating the necessary components. This mechanism enables the QVB11133 Photointerrupter to detect the presence of an object within its operating range.

Conclusion

The QVB11133 Photointerrupter, with its slot-type design, Transistor output, and wide operating range, is suitable for use in a variety of sensing applications. Its ability to detect objects between its emitter and detector provides reliable and dependable operation even for long objects. The QVB11133 Photointerrupter also features a wide temperature range, fast response time, fire-resistent construction, and easy mounting onto circuit boards. As a result, it can be used in various industries and applications, making it a great addition to any system.
