Optical sensors are often used in a variety of industrial applications in order to detect the presence or absence of an object. One type of optical sensors, known as photointerrupters, use a light beam which passes through an object when it is in its detection range and is then interrupted by the object. The interruption of the light beam is then detected and can be used to trigger an event or provide feedback. The OPB903L55 is an example of a photointerrupter which uses a slot type with a logic output.

The OPB903L55 is a flat, low-cost photointerrupter with a logic output, specifically designed for applications requiring a slot type sensing. It is typically used in applications such as package verification, presence or absence detection, and monitoring and detection of product width. The photointerrupter is constructed out of a GaAs infrared emitter and a phototransistor. The infrared emitter will emit an IR light beam which will pass through a slot and be detected by the phototransistor. The interruption of the light beam by an object passing through the slot will then be detected and converted into a logic output signal.

The logic output signal can be used to trigger an event or provide feedback to a control system. For example, in package verification applications, the OPB903L55 can be used to detect the presence of an item passing through the slot and provide a logic output data to an external control system. Additionally, it can be used to monitor and detect product widths by measuring the interruption time of the IR light beam when it is blocked by the item.

Due to the OPB903L55\'s low cost, flat design, and logic output, it can be used in a variety of applications requiring a slot type sensing. The photointerrupter is a reliable solution for applications such as package verification, presence or absence detection, and monitoring and detection of product widths. Additionally, its low profile and compact design make the OPB903L55 an ideal choice for a variety of industrial applications.
