Optical Sensors - Photointerrupters - Slot Type - Transistor Output are widely used for detection tasks. The sensor is able to discern objects and emits an electrical signal based on certain criteria. A popular type of such sensor is the QVE00039, which was developed by Mitsubishi Electric Corporation. Its application field and working principle are illustrated in this article.

The QVE00039 is an optical sensor that features high sensitivity, good accuracy, and wide application. It is mainly used for the detection of objects, the detection of movement or speed, the counting of objects, and first and foremost, the edge detection of a signal. The Photo interrupter-type sensor is able to receive Optical signals from Light-emitting diodes, and outputs an electrical signal in response. This Transistor Output type photointerrupter is able to detect objects with a slot width of 0.6mm, making it a versatile tool for detecting small and large objects.

In practical application, the QVE00039 may be used for a wide variety of tasks. It can be used to detect the presence of an object, the density of objects, the presence of parts or objects in assembly lines, or for feedback control in industrial automation. In addition, the sensor can be used for counting tasks, such as counting the number of coins or optical marks on paper. As a transistor output device, it can be used to drive relays, lamps, alarms, etc.

The working principle of the QVE00039 Photo interrupter-type optical sensor is based on the interruption of the light beam. The device consists of an emitter and a receiver, both mounted in the same housing. The emitter emits a light beam which is then interrupted or obscured by an object placed in front of the receiver. When this occurs, the receiver will detect this interruption and output an electrical signal based on the criteria stipulated by the user. Additionally, the QVE00039 features differential output, meaning that the output signal will be amplified when compared to the signal when no object is present.

The QVE00039 Photo interrupter-type Optical sensor is a highly reliable and efficient tool for various automation and detection tasks. It is very resistant to environmental factors, such as dust or humidity. Additionally, the differential output feature allows users to better monitor their application, as they can be alerted when an object is present.
