Optical sensors are devices designed to detect visible light and generate a signal. Photointerrupters are one type of optical sensor that utilizes an emitter and receiver to detect the presence or absence of an object passing through the gap. Specifically, slot type photointerrupters are characterized by their sensor operation and internal construction. The OPB830L55 is a popular slot type photointerrupter with a transistor output. In this article, the application field and working principle of the OPB830L55 are discussed.

Application Field of OPB830L55

The OPB830L55 is a slot type photointerrupter with a transistor output. It is an ideal solution for applications where an object passing through a gap is detected, such as a robotic arm. The OPB830L55 can also be used in applications that require precise timing, such as a conveyor belt. In addition, the OPB830L55 may be utilized in residential, commercial, agricultural, and industrial applications.

Working Principle of OPB830L55

The OPB830L55 utilizes a light-emitting diode to emit infrared light which is then detected by a phototransistor in the slot. When an object passes through the gap, the light from the infrared LED is blocked, causing the phototransistor to turn off and the output signal to turn low. Conversely, when an object is present, the output signal remains high as the infrared light illuminates the phototransistor. Additionally, the OPB830L55 has a low rise/fall time for fast response.

Conclusion

The OPB830L55 is a slot type photointerrupter with a transistor output. It is widely used in automation applications that require detection of objects passing through a gap, and precise timing. The OPB830L55 utilizes a light-emitting diode and a phototransistor to detect the presence or absence of an object. As such, it is an ideal solution for a variety of residential, commercial, agricultural, and industrial applications.
