Optical Sensors have become an integral part of our daily lives, from determining the speed and direction of a car in the driverless car system to recognizing objects in the home automation system. OPB773T is a mini type, compact, and affordable photoelectric sensor. It is widely used in different industrial applications. This article will explore the OPB773T application field and working principle.

OPB773T is an optical distance sensing switch. This range-sensing switch is capable of accurately detecting objects from a distance of 2 m up to a few millimeters. In this scope, it can detect objects, compare distance, and initiate the alarm signal. It works through the use of pulsed time-of-flight optical sensing technology, measuring the light round-trip travel time and then decides if the target object is present or not.

The OPB773T Photoelectric Sensor is generally used in areas that involve detection of long-distance targets. It can be used to detect the presence of objects like people, cars, boxes, or containers. It can be used in applications like transportation, automobile, automotive, and logistics. It can also be utilized in flow-control, safety-monitoring, and other process-related applications in the industrial environment.

This photoelectric sensor is equipped with pulse width modulation (PWM) and I²C interface. Using these interfaces, the device can support a wide variety of communication protocols such as RS-232, USB, and RS-485. This can enable it to be integrated into the existing system of the industrial environment.

Apart from the flexibility of the communication protocols, OPB773T is also capable of emitting up to 4000 lumens of powerful daylight illumination. This enables the detection of objects at a long-distance effectively. Furthermore, the device can detect objects through glass, plastic film, wood, and other transparent barriers. This helps achieve higher detectability in various scenarios.

The OPB773T Photoelectric Sensor can be easily used in industrial applications due to its low power consumption and small size design. It offers long-ranges of detection without missing any of the targets. Additionally, the device can detect objects at a high accuracy up to 0.2 mm. These features can effectively improve the efficiency of the system.

As for the working principle, OPB773T Photoelectric Sensor emits a LED light signal towards the target object. When the object is detected, the signal will be reflected and received by the photosensor. With the time-of-flight technology, the device is able to measure the time of travel of the light signal and then compare the distance at which the object is detected. Once the object is within the detection range, the output switch will be activated, and the alarm signal will be triggered.

In conclusion, OPB773T Photoelectric Sensor has a wide range of application fields in the industrial environment. It is equipped with different interface protocols to make it easy to integrate into the existing system. The device is also capable of detecting long-distance targets and perform with high accuracy up to 0.2 mm. Using the time-of-flight technology, it can detect the presence of objects with great precision and accuracy. This makes it a reliable tool for long-range distance detection.
