Photoelectric sensor Datalogic 950811270 — industrial diffuse/retroreflective sensing, compact housing

Datalogic 950811270 is a compact photoelectric sensor designed for industrial object detection where non-contact sensing and limited installation space are factors. The sensor belongs to the S100 miniature series with a small housing and multiple mounting options, and it supports diffuse and retroreflective sensing modes for reliable presence/absence detection on conveyors, machines and packaging lines.

Advantages

The S100 form factor provides a very small footprint while keeping robust mounting flexibility with four fixing holes (two threaded at the front and two slotted at the rear). The design omits external adjustments to simplify installation and reduce the risk of unintended changes. Built on Datalogic’s ASIC platform, the sensor supports IO-Link connectivity for programming and parameter adjustment, offers dual output channels and maintains stable digital output behavior during communication. These characteristics make the sensor suitable for compact installations that still require configurability and consistent switching performance.

Suitable for

• Conveyor monitoring and object passage detection
• Machine automation where space is constrained
• Packaging lines requiring non-contact presence/absence sensing
• Retroreflective or diffuse detection applications in industrial environments

Key specifications

• Optical detection modes: diffuse and retroreflective sensing
• Miniature housing dimensions suitable for tight installations
• Four fixing points for flexible mechanical mounting
• IO-Link connectivity for remote configuration and parameterization
• Dual output channels with stable digital output during communication

How to use

Mount the sensor in the required position using the provided threaded and slotted fixing points to align the sensing axis with the target path. Choose the appropriate optical mode (diffuse or retroreflective) based on the application and target surface. Use IO-Link to configure sensing parameters, output behavior and timing where required; because there are no manual adjustment controls on the housing, commissioning and later parameter changes are performed via the connected IO-Link master or compatible configuration tool. Verify sensing range and switching response during initial setup and secure the sensor against mechanical interference.

Recommendations

Install the sensor with stable mounting to prevent movement that can affect detection, keep the optical window free of dust and debris, and use IO-Link for fine tuning of sensitivity and timing rather than attempting mechanical adjustments. For retroreflective applications, select an appropriate reflector positioned perpendicular to the beam to ensure reliable operation.
