Photoelectric sensor Datalogic S3Z, diffuse/retro-reflective optical sensor, MPN 95B010351

The Datalogic S3Z is a compact photoelectric sensor designed for reliable object detection and presence sensing in industrial automation. It supports diffuse and retro-reflective optical detection modes, enabling detection of a wide range of targets with different surface properties. The sensor is intended for applications where space is limited but consistent optical performance is required on conveyor lines, packaging machines and automated equipment.

Advantages

The S3Z offers flexible optical operating modes that accommodate reflective and non-reflective objects without mechanical adjustment. Its compact housing simplifies installation in tight spaces and on moving machinery. The sensor provides stable detection over typical working distances for small to medium-sized automation tasks and is compatible with standard mounting and connection practices in industrial environments.

Suitable for

• Object presence detection on conveyor belts
• Package edge and gap sensing in packaging lines
• Part detection in assembly and machine-tending equipment
• General proximity detection where optical sensing is required

Key specifications

• Optical detection modes: diffuse and retro-reflective
• Sensing principle: photoelectric (optical) detection
• Application environment: industrial automation and machine vision proximity tasks
• Form factor: compact sensor housing suitable for constrained installations

How to use

Install the sensor on a stable bracket or mounting point aligned with the target path. Use the appropriate optical mode for the application: diffuse mode for direct reflection from the target surface, retro-reflective mode with a reflector for distant or low-reflectance objects. Adjust position and aiming to obtain consistent signal response over the intended sensing range. Connect the sensor according to system power and signal requirements and verify detection using test targets representative of production parts.

Recommendations

Place the sensor where its optical axis has a clear line of sight to the target and avoid mounting in positions exposed to direct ambient light sources that may affect detection. For unstable or highly reflective targets, test both diffuse and retro-reflective setups to determine the most reliable configuration. Regularly inspect the sensing window and clean it from dust or contaminants to maintain consistent performance.
