| Pin Name | Description | |----------|-------------| | VCC | Power Supply | | GND | Ground | | OUT | Digital Output |

Functional Features

The sensor utilizes an infrared LED and a phototransistor to detect the presence of an object. When the object is within the sensing distance, the infrared light emitted by the LED is reflected back to the phototransistor, causing the digital output to switch state.

Advantages and Disadvantages

Advantages

• High sensitivity
• Compact size
• Fast response time
• Wide operating temperature range

Disadvantages

• Limited sensing distance
• Susceptible to ambient light interference

Working Principles

The OPB861N51 operates based on the principle of reflection. When an object enters the sensor's detection range, it reflects the emitted infrared light back to the sensor, triggering the digital output signal.

Detailed Application Field Plans

The OPB861N51 sensor finds extensive applications in various fields, including: - Industrial automation for object detection and counting - Robotics for proximity sensing and obstacle detection - Automotive for position sensing in assembly lines - Consumer electronics for touchless switches and proximity sensors
