OPB983L51Z

Introduction

OPB983L51Z is a logic output slot type photointerrupter used primarily in applications where the light-to-output interface can be used to detect the presence or absence of objects. The slot type photointerrupter consists of an LED optical source on one side and a pair of photodetectors on the other side. The photodetectors are used to detect the presence or absence of that object, which triggers the connection of the two photodetectors. It is an easy-to-use device for sensing external objects with simple configuration. With a maximum supply current of about 25mA, its operating voltage can vary from 6 to 40 V DC.

Application Field

The OPB983L51Z photointerrupter is used in different types of applications. It can be used for simple sensing of external objects with a supply current of less than 25mA and an operating voltage of 6 to 40 V DC. It is suitable for applications such as presence or absence detection, speed control, counting, and as an interface for logic control.

The OPB983L51Z photointerrupter is also used in consumer electronics, light and automation control products. It can be used in automotive, medical, aerospace, industrial, and commercial applications, as well as in applications where light can be used as an input device.

The OPB983L51Z photointerrupter is also used in applications where optical feedback is used to improve environmental control. This type of application is becoming more popular due to its flexibility in controlling the environment based on light signals.

Working Principle

The working principle of the OPB983L51Z photointerrupter is quite simple. The device consists of an LED and a pair of photodetectors. When an object is placed between the LED and the photodetectors, the photodetectors detect the presence or absence of light depending on the position of the object. This triggers the ON-OFF circuit resulting in the connection of the two photodetectors. When the two photodetectors are connected, the output turns ON and when they are disconnected, the output turns OFF.

The OPB983L51Z photointerrupter uses a principle called “Dark Detection”. This means that the LED will be switched off and the photodetectors will detect the absence of light. This allows the device to be used in applications that require darkness detection.

The OPB983L51Z photointerrupter can be used in both linear and angular applications where object detection is required in any direction or orientation of the device. It can detect the presence and absence of objects in multiple angles or directions by adjusting the LED and photodetector combination through the installation angle.The OPB983L51Z photointerrupter is also very fast in responding to objects. It has a response time of less than 1 ms.

Conclusion

In conclusion, the OPB983L51Z is a logic output slot type photointerrupter that is used in applications where an easy-to-use light-to-output interface is required. It has a maximum supply current of 25mA and operating voltage of 6 to 40 V DC, and its dark detection feature makes it suitable for applications that require darkness detection. It is also capable of detecting objects in linear and angular applications and is very fast in responding to objects.
