Optical sensors are devices that convert energy from the optical domain into a physical quantity such as electric current, voltage, or frequency. Photointerrupters are commonly used for sensing of an object, and they are found in non-contact sensors which often have to do with automatic door openers, parking assistance systems, gaming systems, and printer sensors. The OPB993T55 specializes in slot type sensors with a logic output. It is able to detect objects through infrared beams, and this makes it highly useful for non-contact sensing.

The OPB993T55 employs a phototransistor output to detect an object, as well as an infrared LED with a complex lens and a high sensitivity phototransistor. The logic output of the OPB993T55 is able to provide a defined state output for a defined input. It can provide a digital output with a signal strength of 5V, as well as an analog output (on certain models) that can provide a signal at 3.3V or 0V when an object is detected.

The OPB993T55 has a high integrated PC board which helps reduce the size of the overall sensor. It is designed with an optimized light path and an ultra-thin base, which makes it possible to fit the device into tight spaces. The device itself is very resistant to dust and dirt, and it also offers short response times and long operating distances.

One of the primary application fields for the OPB993T55 Photointerrupter is object sensing, as it can detect objects at a range up to 50 cm away. It is frequently used in industrial automation and robotics, and its ability to detect objects without having to directly make contact makes it a valuable asset in many applications.

Another common application field for the OPB993T55 Photointerrupter is automotive safety. It can detect the presence of an object, such as a person or animal in the path of a car, and then activate a warning system. It can also be used in systems that activate door locks or controlled braking.

The OPB993T55 Photointerrupter is also found in a wide variety of home appliance applications. It can be used in automatic door openers and closers, window openers, and other items that need sensor detection. It is also ideal for gaming systems and printer detectors.

The working principle of the OPB993T55 Photointerrupter is quite simple. It consists of an infrared LED which sends out an infrared beam, and a high sensitivity phototransistor which can detect the beam. When an object passes within range of the detection beam, the phototransistor will detect the interruption of the beam and the sensor will provide a defined output signal.

The OPB993T55 Photointerrupter is a powerful and reliable device that offers a wide range of applications in the field of object sensing and vehicle safety. Its compact size and high sensitivity make it an ideal choice for applications that require non-contact sensing and logic output.
