OPB835L51 application field and working principleOptical sensors, as its name suggests, utilize light to provide a detection signal. One of the most widely used optical sensors is the Japanese photointerrupter, which detects interruptions in light beams and is called a slot type. Among these, the OPB835L51 has a built-in gallium gallium-arsenide (GaAs) infrared LED emitter (infrared light-emitting diode). This photointerrupter is a slot type, with an output signal of the transistor type.The OPB835L51 is used in a variety of applications, including motion sensing, vending machines, and photoelectric counter applications. It is small and easy to mount, making it especially suitable for applications with limited space. The OPB835L51 also has a high sensitivity and low power consumption, which is necessary for some battery-operated applications.The working principle of the OPB835L51 is relatively simple. It consists of 4 separate pins: a positive power pin (which enables the light emitter), a ground pin (which turns off the light emitter), and two output pins (which provide the output signal when interrupted).The light emitter emits light to a reflector located on the other end of the photointerrupter. When an object interrupts the light beam, the output signal of the transistor type is generated on the output pins. Depending on the configuration, the output can be either positive or negative.The OPB835L51 is ideal for applications where space is limited or power consumption is a concern. It is also easy to mount and provides reliable performance in a variety of applications. This makes it a great option for applications such as optical switching, photocell counter, electric door sign, and vending machine operation.Thanks to its simple design, it is easy to set up and provides a reliable way to gather information from the environment.
