OPB380P51

Introduction

The OPB380P51 is a slot type, transistor output photointerrupter optical sensor that is designed for applications where a small, effective, long-range photodetection is required. The OPB380P51 is a monolithic integrated circuit that includes an infrared-emitting LED and a matched phototransistor in a single package. The OPB380P51 also offers a wide range of detection distances from 0.5 to 50 millimeters to accommodate a variety of applications.

Application Field

The OPB380P51 is ideal for use in a wide variety of applications that need effective, long-range photodetection, such as motorized vehicle detectors, slot type sensor applications, and linear array imaging. Additionally, the OPB380P51 is perfect for use in industrial code reading, factory automation, and wide range position sensing applications. The OPB380P51 can also be used in measuring, control, and safety systems, as well as motor, visible-light, and presence control.

Working Principle

The OPB380P51 is an all-in-one sensor that typically requires an addition of a power supply for operation. The LED and phototransistor are both mounted on a single chip in the package, and the light emitted from the LED is used to control the output of the phototransistor. The OPB380P51 features an integrated amplifier and hysteresis circuit that input a change in light intensity into an output signal. The hysteresis circuit provides an input threshold that reduces the amount of external noise that affects the output signal, allowing for improved accuracy and reliable operation.

The OPB380P51 also features an adjustable finger and/or cover that can be adjusted to achieve different detection distances. The adjustable finger and cover can be adjusted with a precision screwdriver, and with the adjustable components the OPB380P51 can be calibrated for a detection distance of between 0.5 and 50 mm. This adjustable component also allows the OPB380P51 to detect objects from various angles, making it suitable for a wide range of applications.

The OPB380P51 is also specifically designed to reduce power consumption, with a low current consumption of 0.45 mA. This low current consumption allows for longer battery life and makes the OPB380P51 especially well suited for use in battery-driven applications.
