Optical sensors are used in a wide variety of applications, from industrial to consumer applications, in order to detect objects and convert an optical signal into an electronic signal. The OPB880L51Z is a type of optical sensor that falls into the category of photointerrupters. Specifically, the OPB880L51Z is a slot type photointerrupter with a transistor output. It is a general-purpose, miniaturized, RoHS-compliant, optical sensor.

The OPB880L51Z is used primarily in applications that require sensing a small, flat object. This includes in applications such as sheet feeder, paper vend, and stacker detection. It is a high-resolution, low-profile, and low-cost optical sensor. It is also used in other applications such as photoelectric device, paper end detection, and object presence detection.

The OPB880L51Z features a high response frequency, making it an ideal choice for applications that require precise timing or accurate detection of thin objects. Its high-frequency response is generally greater than 100KHz. It also has a wide detection angle of more than 180 degrees, enabling it to accurately detect objects in any direction. Additionally, it has a low background noise ratio, ensuring precise detection.

The working principle of the OPB880L51Z is based on the interruption of a light path between an infrared light-emitting diode (LED) on one side of the slot and a phototransistor on the other. When the light beam from the LEDs is blocked by an object passing through the slot, a drop in the output voltage is detected by the phototransistor. This drop in voltage can be used to trigger an event, such as the activation of a relay.

In order to ensure reliable performance of the OPB880L51Z, a variety of protective measures are employed. These include protection against interferometry, cross talk, and noise. Additionally, the device is designed to be resistant to environmental conditions such as dust, humidity, and temperature. Furthermore, it is designed to be immune to mechanical interferences, such as vibration and shock.

The OPB880L51Z is a versatile and cost-effective optical sensor solution. Its high-performance features make it suitable for a wide variety of applications. The presence of protective components ensures reliable performance in challenging environments. The wide detection angle ensures accurate detection of small objects in any direction. Finally, its low-cost enables it to be used in cost-sensitive applications.
