The OPB973T11 is an optical sensor categorized as a photointerrupter, slot-type, and logic-output model. It is a device that uses a phototransistor to employ electromechanical principles. When an external object is detected by the sensor, an output signal is created. The OPB973T11 operates over a range of voltages from 4.5V-14V, has a trigger speed of 0.75us, and can handle an ambient light of 10,000 lux.

The OPB973T11 provides a wide selection of applications, including door and window proximity detection, and notification switches. This versatile optical sensor is also used in automation processes, home security systems, and in robotics. Furthermore, it is an ideal solution for applications involving shelf-level sensing and material height detection, as it can identify objects in an accuracy of 0.5mm.

The working principle of the OPB973T11 lies in the use of phototransistor technology. The device has a built-in active infrared LED that emits light into the sensing area. The photo transistor mounted in the sensor head receives the reflected infrared light, allowing for the detection of an object when there is a break in the sensing line. When the object passes through the beam, the output is sent to a controller via the built-in logic circuit.

The OPB973T11 is equipped with various features that enhance operation. It has an adjustable sensing distance of 10-30cm, and includes over- and under-voltage protection. The device is also IP67 rated, meaning it is dust-proof and waterproof. Moreover, it has a power consumption of only 50mW, further increasing its energy-saving performance.

Thanks to its wide range of features and capabilities, the OPB973T11 is a reliable and economical solution for photointerrupter applications. The device offers high accuracy and stability as well as an extended service life—up to 10 million switching cycles. The OPB973T11 is also compact, weighing only 64g, allowing for convenient and easy installation.
