Optical sensors are widely used in many industries due to their accurate data collection and high reliability. Photinterruptors, also known as slot type photo sensors, are a type of optical sensor that is actuated when a beam of light is broken. This type of sensor commonly uses an infrared LED as the light source and and a transistor as the output. The QVB11223 slot type photo interrupter with a transistor output is an example of such a device.

The QVB11223 consists of an infrared LED and a four-point detection phototransistor. The housing is composed of a pair of black body and two lead pins. It is designed to run on a supply voltage of 5V and has a maximum detectable range of 13mm. The sensor’s built-in amplifier circuit reduces the output current of the phototransistor, so it can accurately detect the position of an object as small as 0.5mm. This is useful in applications that require precise control, such as when checking for the presence of small objects or detecting the diameter of a material. Additionally, the QVB11223 can be used to count the number of objects passing through a section of a production line.

The working principle of the QVB11223 is simple. When the slot between the pins is blocked, the infrared LED will emit a beam of infrared light. This beam is detected by the phototransistor, which will then convert it to an electric current. If the slot is open, the light will not be detected and the current will remain unchanged. The transistor output will change depending on the detection level, allowing the signal to be used to control the operation of a variety of devices.

The QVB11223 is highly reliable and its small size makes it ideal for compact applications. Its fast response time and low power consumption make it a cost-effective solution for industrial applications such as safety switches, end-stop sensors, and machine vision systems. Additionally, it has a wide operating temperature range of -30°C to 80°C, making it suitable for use in a variety of environments.

The QVB11223 slot type photointerrupter with transistor output is a versatile and reliable optical sensor which can be used in a wide range of industrial applications. Its accurate detection, small size, and low power consumption make it ideal for applications that require precise control and monitoring.
