onsemi Reflective Optical Sensor Through Hole Miniature 4-Pin Phototransistor Output QRE1113

onsemi QRE1113 Reflective Optical Sensor is a highly compact miniature optical sensor designed for reflective object detection in electronics and optoelectronics applications. This through hole sensor package includes a diode emitter and a phototransistor receiver, allowing it to detect objects by reflecting emitted IR light back to the phototransistor.

With a small footprint of 3.6 x 2.9 x 1.7 mm and 4-pin configuration, it fits efficiently into circuit designs requiring low profile optical sensing components.

Its fast rise and fall times of 20 microseconds make it ideal for applications needing rapid response such as position sensing, counting, or object detection in industrial automation and robotics.

The sensor operates reliably at temperatures ranging from -40°C to 85°C, making it suitable for use in various environmental conditions. Typical applications include integration in manufacturing equipment, instrumentation, and embedded electronic systems where non-contact object sensing is required.

The sensor features phototransistor output for straightforward electronic interface. The miniature through hole package ensures easy assembly on standard PCBs. This device comes packaged in tubes for streamlined insertion and handling.

Its compact size supports high-density circuit layouts. Reflective sensing eliminates the need for mechanically complex sensing arrangements. Compatible with a variety of optocoupler and photodetector applications. Ideal for incorporation in power connectors and electronic component monitoring.
