Introduction to OPB471N11
The OPB471N11 is an optical sensor known as a photointerrupter which belongs to the slot type with a logic output. The OPB471N11 is a normal-open logic-output reflective type. It adopts an infrared emitting diode and photodiode as the light emitter and detector. This photointerrupter consists of a pair of transmitting and receiving components that are located on opposite sides of the opening of the target slot. It is used to detect the status of an object by detecting the presence or absence of the target object. The OPB471N11 optical sensor is reliable, easy to use, and has a wide range of applications.

Applications of OPB471N11
The OPB471N11 optical sensor can be used in applications that require the detection of the presence or absence of an object including counting, position detection, press control, and emergency stop in automation. It can be used in various positioning applications in industrial automation and robotics. It can also be used in operating machines with rotating parts, such as car washes, vending machines, and food processing equipment. Additionally, it can be used for window/door open sensors in home automation systems. The OPB471N11 can also be used in electric-toy operation control systems and small home electric appliances.

Working Principle of OPB471N11
The OPB471N11 photointerrupter functions when a target object is present. This means, on one side of the slot, an infrared emitting diode transmits a specific wavelength of light which is then reflected off the object and received by the photodiode on the opposite side of the slot. When the target object is in position, it is detected by the OPB471N11 and the logic output changes from its normal-open state to a closed-state. When the target object is removed, the logic output changes back to its open-state.

Conclusion
The OPB471N11 optical sensor belongs to the slot type with logic output. It is a reliable and easy to use sensor with a wide range of applications including position detection, press control, emergency stop, window/door sensor, and small home electric appliance. It works by detecting the presence or absence of the target object. The OPB471N11 has a normal-open logic-output reflective type and a pair of transmitting and receiving components that are located on opposite sides of the opening of the target slot. Therefore, the OPB471N11 is the perfect choice for automation, robotics, and home automation applications.
