The OPB390N11Z is classified as an Optical Sensors - Photointerrupters - Slot Type - Transistor Output device. This component is designed to detect and measure the presence or absence of a metal or plastic target object as it passes between its two photointerrupter slots. The three-terminal general purpose Type N (with one transistor outlet) OPB390N11Z is ideal for applications where the detection of target objects is critical and automation is necessary. This photointerrupter offers a number of advantages over traditional detection methods, including increased reliability, reduced cost, and increased simplicity. By using an optical sensor, the detection of objects is much faster and more accurate than with mechanical sensors. Additionally, since the optical system uses light to detect the object, there is no need for contact, which greatly reduces the risk of contamination or mechanical failure. The OPB390N11Z features a unique construction that utilizes an LED emitter and NPN transistor amplifier which together creates a high-sensitivity detection system. The OPB390N11Z is designed with a dual sensing slot, which is activated when an object passes between the two slots. When the object passes between the slots, the LED sends a signal to the NPN transistor amplifier, which amplifies this signal and produces a voltage proportional to the size of the object detected. This amplified voltage is then output from the device as an on/off signal which can be interpreted by a controller to determine the presence or absence of an object. Due to the accurate sensing response and the two-slot design, the OPB390N11Z can accurately detect objects with objects up to 1.4mm in diameter.The OPB390N11Z also includes a built-in protection circuit which is designed to prevent errors caused by electrostatic discharge, surge voltage, and over current. Additionally, the OPB390N11Z incorporates a built-in temperature compensation circuit which ensures that the LED maintains a consistent emission intensity despite environmental temperature fluctuations. This feature helps to ensure reliable detection even in the harshest conditions. The OPB390N11Z is available in a variety of packages, including surface mount and through-hole types. Additionally, the OPB390N11Z can be operated from a wide range of input voltages, including +5V, +12V, and +24V. This makes the device suitable for a wide range of applications, including automation systems, industrial process control, and medical devices. The OPB390N11Z is an excellent choice for applications requiring reliable detection and a low cost solution. The combination of the reliable optical detection system and the built-in temperature compensation circuit make the OPB390N11Z a reliable and cost-effective solution for a variety of target detection applications.
