Optical sensors are devices that function by sensing light, typically using a photodiode or phototransistor. They are often used in industrial applications such as automated parts manufacturing, barcode reading, machine vision, and motion sensing. The QVB21114 is a type of slot-type, transistor output optical sensor. It is designed to detect objects passing through a light gap in an assembly line or as part of a production process and is suitable for various control systems such as conveyor systems, capacitive signal systems, or any other system requiring a light shutter.

The QVB21114 is a single-channel slot-type photointerrupter. It is constructed out of a special plastic body that allows the user to mount it to the surface of an assembly line. On the inside of the plastic body is an LED and an internal phototransistor. The LED acts as the light source while the phototransistor serves as the sensing element.

The working principle of the QVB21114 is based on the fact that when light passes through a gap in an assembly line and is blocked by an object, the array of light falls into the phototransistor which then produces an output signal. The signal is then amplified by the built-in amplifier and further processed by a comparator circuit before being output as a transistor signal. The transistor output can then be used to drive external relays, lights, etc.

The main application for the QVB21114 is as an object detector for an assembly line or other production process. When an object passes through the light gap, the phototransistor produces a signal that can be used to trigger an action, such as turning on a light or activating a motor. The QVB21114 is also suitable for use in capacitive signal systems where the output of the phototransistor can be amplified and used as a control signal for an external circuit. In addition to these applications, the QVB21114 is also suitable for use in various data logger and monitoring systems.

The QVB21114 is an excellent choice for use in many types of industrial applications. It is highly reliable, easy to install, and extremely cost effective. Furthermore, the QVB21114 uses very little power, which makes it an ideal choice for applications where power consumption is a consideration. Overall, the QVB21114 is an excellent opto-electronic solution for industrial applications that require an object detection system that is reliable, cost effective, and energy efficient.
