The EE-SY172A-1 is a reflective photosensor manufactured by Omron. These sensors detect the presence of an object by sensing light reflected directly off the object's surface. It's part of the EE-SY series which are known for their compact size and ease of integration.

Applications

• Object Detection: Detecting the presence or absence of objects on a production line.
• Paper Detection: Sensing the presence of paper in printers and copiers.
• Edge Detection: Identifying the edge of a material.
• Positioning: Determining the position of a moving object.
• Coin Detection: Used in vending machines and other coin-operated devices.

Features

• Reflective Type: Senses light reflected directly from the object.
• Compact Size: Allows for integration into small spaces.
• High Sensitivity: Capable of detecting objects with low reflectivity.
• Fast Response Time: Provides quick detection of changes in object presence.
• Infrared LED: Uses an infrared LED as the light source.

Benefits

• Simple Operation: Easy to set up and use.
• Reliable Detection: Provides consistent and accurate detection.
• Versatile: Suitable for a wide range of applications.
• Cost-Effective: Offers a good balance of performance and price.

Additional Details

The EE-SY172A-1 typically operates on a 5V DC power supply. The output is usually a digital signal (either HIGH or LOW) depending on the presence or absence of an object. The sensing distance is typically a few millimeters, depending on the reflectivity of the target object. It uses an infrared LED and a phototransistor. Proper alignment and consideration of the object's surface properties are important for reliable detection. Consult the Omron datasheet for detailed electrical characteristics, dimensions, and application notes. The "-1" suffix might indicate a specific variation in connector type or cable length.
