Optical Sensors - Photoelectric, IndustrialThe OPB720B-12Z is an industrial-grade photoelectric sensor, utilized in various industrial applications in order to detect and monitor the movement, presence, and/or absence of objects. Its performance is characterized by high precision, sensitivity, and reliability, making it an ideal choice for industrial conditions.The primary components of the OPB720B-12Z are its active and photoreceptor elements, encased in a black plastic housing and equipped with an indicator LED light. The active element emits a visible red light, whereas the photoreceptor element measures the amount of light that is reflected back from the object being monitored. When a certain level of ambient light is detected, the output signal changes and the LED indicator signals the presence or absence of the object.The OPB720B-12Z sensor is most commonly used in identifying and locating objects, particularly those that have reflective surfaces. These objects can include paper, wood, metal, and other materials. It can also be used in applications where the position, alignment, and orientation of an object must be accurately determined.Another common application for the OPB720B-12Z sensor is in safety systems such as industrial robots and vision systems. It is used to detect the presence and absence of an object in a particular area. When used in conjunction with a control system, it can be used to stop accidental contact with dangerous materials or prevent unauthorized entry. Its high reliability and accuracy makes it an ideal choice for these safety systems.The working principle behind the OPB720B-12Z sensor is simple and effectively outlined in so-called \'passive sensing\'. In this particular setup, the active element emits a visible red light toward the object to be measured, while the photoreceptor element measures the amount of light that is reflected back from the object. As the amount of ambient light increases, the signal output from the photoreceptor element will decrease. Conversely, when the ambient light decreases, the signal output from the photoreceptor will increase.In most cases, the OPB720B-12Z can be used in either an active or a passive mode depending on the application. In an active sensing mode, the sensor operates by continuously emitting light. The signal output from the photoreceptor element will reflect the presence or absence of an object based on the amount of light that is reflected back. In a passive sensing mode, the sensor does not emit light and only measures the amount of ambient light that is reflected off an object.Since the OPB720B-12Z is a reliable industrial-grade photoelectric sensor, it can be used in a wide variety of applications, from industrial robots and vision systems to detecting the presence of dangerous materials or unauthorized entries. Its ability to quickly and accurately measure the presence or absence of an object makes it a great choice for industry. Furthermore, its ease of installation and operation make it a valuable asset to any industrial facility or worksite.
