OPB685-3 Application Field and Working Principle

Optical Sensors - Photointerrupters - Slot Type - Logic Output is the category which OPB685-3 belongs to. A photointerrupter is composed of an infrared LED, which emits light, and a photosensor, which detects the light. The combination is used to detect objects passing through a gap, or slot, between the two components. OPB685-3 is a specific type of photointerrupter which has a logic output, meaning that the output is either high or low depending on whether the photointerrupter is detecting a passing object or not.

Generally speaking, the application fields of OPB685-3 are mainly for detecting objects and for positioning of objects. For instance, it can be used to detect the presence of packages, moving parts, and/or conveyor lines. The logic output feature also allows for more complex application possibilities. By combining multiple OPB685-3 photointerrupters, it’s possible to accurately control the speed of moving parts, allowing for more precise control. OPB685-3 can also be used in applications where objects are required to be accurately placed in a designated spot relative to the photointerrupter.

The working principle of OPB685-3 is based on the fact that it is composed of an infrared LED and a photosensor. When an object passes between the two components, the LED will emit infrared light, which will be detected by the photosensor. When the LED is turned on, it will provide the logic output of high voltage. When the object passes between the two components, the light will be blocked, which causes the output to become low voltage.

The working principle of the OPB685-3 photointerrupter is further enhanced by the fact that it has a wide range of customizable features. It has a wide operating voltage of 2.0V to 24V and current consumption of ≤ 100mA. It also has a wide ambient ambient light range of 38Lux to 1000Lux and a wide operating frequency range of <50kHz to 5MHz. This makes it suitable for a wide range of applications.

The advantages of using OPB685-3 photointerrupters are numerous. First, they offer a reliable detection system since they are composed of an infrared LED and a photosensor. They are also highly customizable, allowing for greater flexibility in design. Additionally, they have a wide operating voltage, current consumption, operating frequency, and ambient light range. Finally, they are easy to install and do not require any additional wiring. Overall, the OPB685-3 photointerrupter is the ideal choice for those who require a reliable, customizable, and easy to install opto-sensor.
