Optical Sensors - Photointerrupters - Slot Type - Transistor Output

The HOA2862-002 photointerrupter (slot type/transistor output) is a specialized optical device which can be used for a variety of applications. The photointerrupter utilizes an embedded LED that emits infrared light across a gap in its slim design. The light is then picked up by a built-in, miniature phototransistor, and used in a number of ways to detect presence, speed, angular displacement, and much more.

Working Principle

The slot type/transistor output photointerrupter works by detecting a break in the infrared light beam passing through its gap. Its light factor can be adjusted to detect a wide range of objects passing within the gap, from a small pinhead to a small ruler. When the gap is interrupted, the integral phototransistor is blocked and the output signal changes, indicating a “true” condition. When the interruption is cleared, the output signal returns to its “false” condition.

Features and Benefits

The HOA2862-002 photointerrupter offers many features and benefits, such as:

• Small and slim design
• Integrated LED & phototransistor
• High sensitivity
• Can detect a variety of object sizes
• Wide range of operating temperature
• Long-term reliability and consistency

Applications

The HOA2862-002 photointerrupter offers a wide range of applications from presence/absence detection, speed/rotation detection, angular displacement, to providing an end-of-line signal for machinery, and more. Its slim design and adjustable sensitivity makes it suitable for a multitude of applications in various industries, from automotive and aerospace to consumer electronics.

Conclusion

To sum it up, the HOA2862-002 photointerrupter is an ideal solution for a variety of industrial sensing applications. Its small and slim design, along with its many features and benefits, make it perfect for embedded sensing solutions in various industries.
