Introduction

OPB882N55Z is a slot-type photointerrupter, consisting of an infrared LED and an phototransistor. It is a transmissive optical sensor, designed to detect the presence of objects or to measure the passage of objects. The transmissive detection technique provides a reliable, fast and low-cost solution for detecting and measuring objects. It is used in a variety of industrial applications, such as automatic door open/close sensors, ATM machines, automated factory equipment and vending machines.

Working Principle

The basic working principle of the OPB882N55Z is light-emitting diode (LED) and phototransistor in a single package. The IR LED produces a beam of infrared light, which is guided towards the phototransistor. When an object blocks the IR light beam, the phototransistor stops conducting. The transistor output is then turned OFF, indicating that an object is blocking the photointerrupter. The transistor output can be used to control a variety of electronic circuits and applications.

Features and Specifications

OPB882N55Z has many features that make it an ideal choice for applications such as door opening and closing sensors, ATM machines, automated factory equipment and vending machines. It is a slot-type photointerrupter with transistor output. It has a very small package size (4.6 x 3.4 x 0.9 mm), and it has a wide viewing angle (45°). It has a built-in resistor for enhanced reliability and long life. It normally operates from a 3.3V to 5VDC power supply. The supply current is typically less than 25mA. The effective distance between the LED and phototransistor is 0.3mm. It has a maximum operating frequency of 3MHz.

Applications

OOPB882N55Z is used in a variety of industrial applications, such as automatic door open/close sensors, ATM machines, automated factory equipment and vending machines. It is also used in mechanical switch replacement applications. It can be used to detect and measure a variety of objects that pass through a slot or opening. It can also be used as a limit switch to detect the presence or absence of an object. It is ideal for applications with high ambient light and where fast response time is required.

Conclusion

OPB882N55Z is an infrared slot-type photointerrupter with a transistor output. It is a transmissive optical sensor, designed to detect the presence of objects or to measure the passage of objects. It is used in a variety of industrial applications, such as automatic door open/close sensors, ATM machines, automated factory equipment and vending machines. It has many features that make it an ideal choice for applications, such as its small package size, wide viewing angle and built-in resistor for enhanced reliability. It has a maximum operating frequency of 3MHz and a maximum effective distance between the LED and phototransistor of 0.3mm.
