The OPB481N11Z is an optical sensor from the Photointerrupter family of products under the slot type with a logic output. It is an ideal device for providing a stable and reliable switching for a variety of applications; where the photointerrupter device is used to detect the presence of a material, the OPB481N11Z provides a safe, low-cost and space saving solution.

The OPB481N11Z consists of an infrared LED and a photosensitive resistor. The two components are mounted on an opal glass wafer and are connected to two bonding paddles. The LED and the detector photodetector are set in an opal glass wafer which serves to increase the signal conversion efficiency of the device.

The physical construction of the OPB481N11Z is designed to ensure reliable operation under different environmental conditions, ranging from extremely small to medium to large size. To operate properly, the device must be mounted in the housing with the LED and detector positioned in the slot. The slot of the device is designed such that, when an object passes through, the detector is exposed to the LED light and voltage is generated at the output terminal. Depending on the type of light wave produced, the output voltage changes in proportion to the amount of light wave that is detected.

Photointerrupters are used in a wide variety of applications, including monitoring systems, traffic signals, production lines, security systems and other automation-related systems. The OPB481N11Z in particular has a wide range of applications, including automotive applications, robotic sensing systems, factory automation, distribution of electrical signals, and communication systems.

The OPB481N11Z provides many advantages over traditional optical sensors and photointerrupters. Its efficiency is greater than 80% when compared to other photointerrupters and it has extremely low noise levels, low power consumption, and a long working life. It is also resistant to interference from other light wave sources. Moreover, due to the small size of the device, it can be mounted in tight spaces and can easily be installed on apparatus without complex modifications.

The working principle of the OPB481N11Z is simple. When an object passes through the slot of the device, the LED sends out a light wave towards the photodetector. As the light wave is detected by the photodetector, the voltage level of the output terminal changes accordingly. Therefore, when the photodetector is exposed to enough light wave, it produces a high output voltage; otherwise, it produces a low output voltage. Thus, the OPB481N11Z provides a stable and reliable switching function for various applications.

In conclusion, the OPB481N11Z is an effective and reliable optical sensor solution that has a broad range of applications. It is designed to offer high efficiency with low power consumption and long life span. Additionally, the device is extremely resistant to interference from other light wave sources and is compact in size, making it easy to install in tight spaces and on apparatus. As such, it is an ideal choice for a variety of applications in production lines, distribution systems, and communication systems.
