The OPB802W55 is an optical slot-type photointerruptor which consists of a transmitter and a receiver housed in a single package. The transmitter module acts as an infrared emitter, while the receiver includes a photosensitive element. Combining the two elements create a highly sensitive interrupting optical switch solution. This type of photointerruptor is often used in applications where repetitive on/off switching is necessary and/or high speed operation is required.

One distinctive feature of this particular model is that it has a transistor output. This configuration enables a high switching frequencies up to 500kHz, as well as, improved immunity to electrical noise from external sources. This type of output is especially suitable for logic level systems, where the signal can be interpreted directly by the logic circuitry, without the need of any external components. Additionally, the photointerruptor is also designed with an operating voltage range of 3.3V ± 10%, enabling a wide compatibility with different systems.

In addition, the OPB802W55 features a housing incorporated with a built-in lens to increase the amount of incident light on the photosensitive element. Due to this, the unit is suitable for longer installation distances. Furthermore, the optical axis of the photointerruptor has been designed to minimize the light-receiving area, increasing the interrupting speed, while the LED cells have been optimized for a long life-span.

In terms of application fields, the OPB802W55 can be used in a wide range of projects, including industrial sensors, optical switches, long range proximity sensing, and light barriers. It is a versatile addition to any electronic board, allowing the user to implement different designs with the same device. Additionally, its construction eliminates the need for external components, which greatly simplifies the overall wiring process.

Overall, the OPB802W55 has been designed to improve the user experience when comparing to other photointerruptors. Its tight dark-on response, high operating frequency, extended operating distance, built-in lens, and transistor outputs, all together to deliver a unique combination to applications where high-speed on/off switching, repetitive operation, and long range sensing are all needed.
