Optical Sensors are devices that detect and measure physical phenomena or properties related to light. Photointerrupters, or slot type sensors, are one type of optical sensor that utilizes a beam of light and a receiving element to sense the position of an object. The OPB993L11 is a members of this category, and is used to detect the presence of a moving object through a light beam. In this article, we will discuss the application field and working principle of the OPB993L11.

Applications

The OPB993L11 is designed for use in non-contact proximity sensing applications. It is suitable for applications such as position sensing, high-speed counting, pulse generation, or process control. The OPB993L11 is highly reliable and suitable for a variety of industrial, commercial, and consumer applications. It is also cost-effective, making it ideal for mass production.

The OPB993L11 is used in a variety of settings, including robotics, factory automation, assembly lines, packaging, digital and analog measuring systems, medical and laboratory equipment, consumer appliances, automotive systems, and more. It is especially suited for applications that have very strict environmental requirements, since it designed to withstand shock, vibration, and temperature extremes, and is also resistant to dust, dirt, and moisture.

Working Principle

The OPB993L11 uses a compact, integrated and solid state optical detector and a through-beam emitter to detect the presence of an object. The emitter consists of a light-emitting diode that transmits an infrared light beam in the 900–950 nm spectral range. The receiver module consists of a phototransistor that is sensitive to the wavelength of the emitted IR signal. When an object interrupts the light beam, the receiver will detect the interruption and output a logic signal.

The OPB993L11 is designed to offer highly precise and reliable performance. It is able to detect objects up to 7.62 cm away with a resolution of 0.3 cm. It is also designed to operate reliably in ambient light up to 200 lux. In addition, the OPB993L11 is designed to achieve a high level of reliability, with an operating life of up to 500k cycles and a 10 year retention period.

The OPB993L11 is powered by an external DC power supply, and has an operating voltage range of 2.5 to 12 V. It has an operating current of 0.3 mA, and it is equipped with ESD protection up to 8 kV, which improves the safety of the device in shock and vibration scenarios. It is also designed with a 500 kHz frequency response, which allows for fast response times and reliable operation even in high-speed applications.

Conclusion

The OPB993L11 is a high-performance slot type optical sensor that is used for proximity sensing applications. It is designed to be highly reliable and relatively inexpensive, making it ideal for mass production applications. It is suitable for a variety of industrial and commercial settings, and is designed to tolerate shock, vibration and temperature extremes. Additionally, it has a 500 kHz frequency response and a resolution of 0.3 cm, making it suitable for fast and reliable position sensing over long distances.
