Optical Sensors – Photointerrupters – Slot Type – Logic OutputThe OPB973L55 is a type of optical sensors known as a photointerrupter slot type with a logic output. It is mainly used to detect the presence or absence of an object by interrupting a beam of light between a transmitter and receiver. As a result, it helps to detect the speed or direction of objects in linear motion like conveyor systems and motorized tools. The OPB973L55 is a passive device that uses an infrared (IR) LED emitter with a receiver module. The LED emitter sends a beam of light across a gap between the transmitter and receiver. When an object passes through or interrupts this light beam, the output from the receiver module (a logic voltage output) is changed, thus helping to detect the presence or absence of the object. AdvantagesThe OPB973L55 provides a very simple and reliable way to detect the presence or absence of objects at a relatively low cost. As it has no moving parts, it is highly durable and requires very little maintenance compared to other detection systems. Additionally, its small and compact size makes it well suited to a variety of applications and its excellent response time gives it a technology edge, even compared to other transistor output IR photointerrupters. ApplicationsThe OPB973L55 is highly suitable for use with industrial machinery and equipment. Its use is particularly beneficial in applications such as conveyor systems, robotics, motorized tools, and vehicle speed measurements, to detect the presence or absence of an object, and to measure the speed or direction of objects in linear motion. Its ability to detect even very small objects makes it ideal for a wide range of applications. FeaturesThe OPB973L55 has a number of features that make it ideally suited to many different applications. For example, it features a logic voltage output, a high operating temperature range, a wide operating voltage range, low power consumption, and a fast switching response time. Additionally, it is able to detect even very small objects of less than 0.2mm thick. ConclusionThe OPB973L55 is an optical sensor suitable for use in a wide range of applications. Its highly reliable and durable design, logical output voltage, and small size makes it suitable for use in industrial machinery such as conveyor systems and motorized tools. Its fast response time and ability to detect deceptively small objects gives it a technology edge even compared to other transistor output types.
