Introduction

The OPB972L51 is a slot type logic output photointerrupter designed to detect objects from meters away. It operates with a detection range from 1 m to 3 m, depending on the size, environment, and other factors. This device is suitable for industrial, consumer, and medical applications due to its high durability, easy installation, low power consumption, and reliability. This article will discuss the possible application fields for OPB972L51 and its working principle.

Application Fields

This device can be used in a variety of applications, including industrial automation, home appliances, and medical testing. The OPB972L51 is capable of detecting objects from up to three meters away, and its easy installation and low power consumption make it suitable for a wide range of applications.In industrial automation, the OPB972L51 can be used to detect objects or passers-by for safety purposes. It can be used in factories or other industrial areas where workers are constantly moving around, and its detection distance can be set according to the size of the area.In the home appliance field, it can be used in automatic light switches or other home automation products. It can detect passers-by in hallways or other areas of the home, and its detection distance can be adjusted accordingly. In addition to this, the OPB972L51 is also suitable for smart appliances, such as refrigerators, washing machines, and dryers.Finally, the OPB972L51 can also be used in medical testing. In medical laboratories, it can be used to detect pipettes, syringes, and other small objects. This device can also be used for detecting body movements and activities, for monitoring the health of patients.

Working Principle

The OPB972L51 is a slot type photointerrupter with a logic (CMOS) output. It consists of two parts: an infra-red emitting diode and a light sensitive receiver, which are housed in an epoxy body.When a person passes by, the receiver detects the infra-red light emitted from the diode, and a logic voltage is sent to the receiver. The receiver then compares the light intensity to a reference level, and outputting a logic 1 if the light intensity is greater than the reference level, and a logic 0 if the light intensity is equal to or less than the reference level.The logic output voltage can be directly connected to an input pin of a microcontroller or logic circuit, providing a clean and reliable signal. The OPB972L51 is also resistant to ambient light, dust, and other environmental factors, ensuring reliable operation and accuracy of the device.

Conclusion

The OPB972L51 is an optical detection sensor designed to detect objects from meters away. It is suitable for a wide range of applications, including industrial automation, home automation, and medical testing. This device operates by detecting infra-red light sent from an emitting diode housed in an epoxy body, and outputting a logic voltage determined by the intensity of the received light. With its easy installation, low power consumption, and reliable operation, the OPB972L51 is a perfect choice for a variety of optical detection applications.
