The ITR1502SR40A/TR8 is a reflective object sensor from Everlight Electronics Co., Ltd. This type of sensor combines an infrared (IR) emitter and a phototransistor receiver in a single package. It detects the presence of an object by emitting IR light and measuring the amount of light reflected back to the receiver.

Applications:

• Line following robots
• Object detection
• Proximity sensing
• Edge detection
• Automated guided vehicles (AGVs)

Features:

• Compact size
• High sensitivity
• Fast response time
• Operating wavelength: 940nm
• Emitter and detector in one package

Benefits:

• Simple object detection: Provides a simple and reliable way to detect the presence of objects without physical contact.
• Versatile: Can be used in a wide range of applications requiring object detection, proximity sensing, or position sensing.
• Easy to use: The integrated emitter and detector simplify circuit design and reduce component count.
• Compact design: The small size of the sensor allows it to be easily integrated into various devices and systems.
• Fast response: The fast response time enables accurate detection of moving objects.

Additional Details:

The ITR1502SR40A/TR8 operates by emitting infrared light from the built-in IR emitter. When an object is present in front of the sensor, some of the emitted light is reflected back to the phototransistor receiver. The amount of reflected light detected by the receiver is proportional to the distance and reflectivity of the object. The output of the phototransistor can be used to trigger a digital signal or to provide an analog signal that represents the distance to the object. The operating wavelength of 940nm is a common standard for IR object sensors. The "TR8" suffix likely refers to the tape and reel packaging for automated assembly.

Everlight is a well-known manufacturer of optoelectronic components, and their reflective object sensors are widely used in various industrial and consumer applications.
