Descriptions:

• The ITR8307/S17/TR8(B) is a compact reflective optical sensor combining an infrared LED emitter and a phototransistor detector in a single package.
• It detects the presence or absence of an object by measuring the reflection of infrared light.
• Commonly used in proximity sensing, object detection, and position sensing applications.

Features:

• High sensitivity due to matched IR emitter and detector.
• Compact SMD package for space-saving PCB designs.
• Low power consumption (suitable for battery-operated devices).
• Fast response time for real-time detection.
• Reliable performance in various environmental conditions.

This sensor is widely used in printers, automation systems, and consumer electronics for detecting paper, tape, or other reflective surfaces.
