Photoelectric sensor Datalogic S50, through-beam/retroreflective/triangulation (model S50, compact industrial sensor)

Datalogic S50 is a compact industrial photoelectric sensor designed for reliable object detection and presence/absence sensing in automated processes. The sensor family supports through-beam, retroreflective and triangulation operating modes, enabling flexible installation options where a small form-factor optical device is required. The S50 is intended for use on conveyor lines, machine parts, and material-handling systems where precise, repeatable detection of parts, labels or product edges is needed.

Advantages

The compact housing allows integration into tight spaces without sacrificing optical performance. Multiple sensing modes (through-beam, retroreflective, triangulation) provide adaptability for different detection tasks and reflectivity conditions. Robust industrial construction ensures stable operation in manufacturing environments, while straightforward optical operation reduces setup complexity and minimizes downtime for calibration.

Suitable for

• Conveyor monitoring and object counting
• Presence/absence verification of components on assembly lines
• Position sensing for packaging and labeling applications
• Detection of small or thin parts where compact sensors are required

Key specifications

• Operating modes: through-beam, retroreflective, triangulation
• Compact industrial housing suitable for tight installation spaces
• Optical detection principle for non-contact sensing
• Designed for integration into automated machinery and material-handling lines
• Suitable for detection of opaque, reflective and low-contrast objects depending on mode

How to use

Install the sensor in a stable position aligned with the target path or the matching reflector/receiver depending on the selected operating mode. For through-beam mode, align emitter and receiver directly across the travel path; for retroreflective mode, position the sensor to face a reflector at the appropriate distance; for triangulation, set the sensor angle and distance to obtain the required detection sensitivity for edges and small parts. Connect the sensor to the control system following the manufacturer’s wiring and electrical requirements and adjust the sensing range and threshold using the device’s optical adjustment features or built-in tuning functions.

Recommendations

For reliable detection, verify alignment and clean optical surfaces regularly. Choose the sensing mode that best matches object characteristics—through-beam for highest immunity to object reflectivity, retroreflective for simplified two-point installation, and triangulation for accurate edge and small-part detection. Test sensor response under actual production conditions and secure mounting to prevent misalignment due to vibration.
