Optical Sensors are used to sense objects that move or detect light in certain environments. Photointerrupters are the most common type of photoelectric sensor, which uses an optical system to detect the presence of an object. The photointerrupter features a transmitting and receiving element which is placed so that when the beam of light is interrupted, the output status of the device changes accordingly. The Slot Type Optical Interrupter, also known as an OPB123B, is a device designed to detect the presence or an interruption of light passing through a gap in between two opposing faces.

The OPB123B utilizes a light sensitive semiconductor chip which is placed between two light blocking plates. When a beam of light is incident on the device, it allows electricity to pass between the plates. This process is interrupted when anything comes into contact with the gap between the two plates, blocking the light. As a result of this interruption, the output status of the device is changed.

The OPB123B is mainly used in the automation and control industry. It can be used to monitor the movement of objects. In this application, it is usually used as part of a control system to detect the presence of an object as it passes a certain point. The OPB123B can detect a wide variety of objects including metallic items, paper, circuits, wires, posters, fabric, plastic, rubber and other non-metallic objects. In automation and control, it can be used as part of safety systems to detect the presence of an intruder, or to detect malfunctioning machinery.

The OPB123B has a logic output, meaning that it can detect the presence or absence of an object and output a logical signal accordingly. This is done by connecting the output pins of the device to a suitable microcontroller or logic circuit. When a beam of light is interrupted, a low logic voltage is outputted from the OPB123B which can then be used to activate an alarm or to shut down a machine.

The OPB123B is a versatile device which has a myriad of applications in the automation and control industry. It is a reliable sensor which can be used to detect the presence or interruption of light and to output a logical signal accordingly. With its ability to detect a wide variety of objects, it can be used for controlling equipment, safety systems and security systems.
