Functional Features

The sensor operates by emitting an infrared light beam and detecting its reflection off an object. When an object is present, the reflected light is received by the sensor, causing the output to switch states. This functionality allows for accurate detection of objects within the sensor's range.

Advantages and Disadvantages

Advantages

• High sensitivity
• Compact size
• Reliable performance
• Wide operating voltage range

Disadvantages

• Limited sensing range
• Susceptible to ambient light interference

Working Principles

The OPB847TX works on the principle of reflective sensing. It emits an infrared light beam and measures the intensity of the reflected light. When an object is present, the reflected light is detected, leading to a change in the sensor's output state. This working principle enables the sensor to effectively detect the presence of objects in its vicinity.

Detailed Application Field Plans

The OPB847TX is widely used in various applications, including: - Object detection in industrial automation - Paper detection in printers and copiers - Proximity sensing in robotics - Slot detection in vending machines

Detailed and Complete Alternative Models

Some alternative models to the OPB847TX include: - TCRT5000: A similar reflective object sensor with a compact design - GP2Y0A21YK0F: An analog distance sensor suitable for object detection applications - QRE1113: A reflective object sensor with a digital output for object detection tasks

In conclusion, the OPB847TX reflective object sensor offers high sensitivity and reliable performance, making it suitable for a wide range of applications in the field of optoelectronics.
