Functional Features

The OPB761T sensor operates by emitting infrared light and detecting its reflection from nearby objects using a phototransistor. This enables it to effectively sense the presence or absence of objects within its specified range.

Advantages and Disadvantages

Advantages

• High sensitivity
• Reliable object detection
• Wide operating voltage range

Disadvantages

• Limited sensing distance
• Susceptible to ambient light interference

Working Principles

When powered, the OPB761T emits infrared light, which is then reflected off nearby objects. The phototransistor detects the reflected light, causing the output to change state based on the presence or absence of an object within its sensing range.
