Optical Sensors - Photointerrupters - Slot Type - Logic OutputThe OPB481T11Z photointerrupter is a slot type optical sensor designed for use in a variety of applications. This device consists of a light emitting diode (LED) and a phototransistor. The device functions by breaking an infrared beam from the LED to the phototransistor. This triggers the phototransistor, which in turn produces a logic output signal. It can be used to detect the presence or passage of objects through a narrow slot, and works well in both low-light and dark environments.The OPB481T11Z photointerrupter is designed for applications that require fast response, such as detecting the passage of small objects. It consists of an opto-isolated surface mounted package and is available with multiple electrical connection options. The device is also resistant to EMI and is backed by a UL certification. The main working principle behind the OPB481T11Z photointerrupter is based on interrupting the infrared beam. A complete break occurs when an object interrupts the beam and the phototransistor produces a logic output signal. When the beam is reestablished, the logic low signal is turned off. The output signal can be used to turn on or off devices such as motors, relays, and solenoids. The OPB481T11Z photointerrupter is suitable for a wide range of applications, including industrial automation, robotics, medical devices, automotive and transportation industries, and consumer goods. For example, the device can be used to automate the cycling of conveyors or to start and stop drive motor speeds when receiving a signal. It is also useful for counting parts in the manufacturing process or triggering alarms for medical equipment. The OPB481T11Z photointerrupter is relatively easy to install and configure. The device requires a power supply voltage of between 3.3V and 24V DC, as well as an output load voltage of between 4.7V and 35V DC. The device is also available in various cable lengths with a maximum length of 3 meters. Additionally, the device offers a high degree of protection against EMI interference.In conclusion, the OPB481T11Z photointerrupter is an effective and reliable optical sensor designed to detect small objects. It is suitable for a wide range of applications, is quick and easy to install, and is resistant to EMI. This device is UL certified, making it a highly reliable and secure solution.
