Photoelectric Sensor Datalogic 950811210 – compact diffuse-mode optical sensor

Datalogic 950811210 is a compact diffuse-mode photoelectric sensor for optical detection of objects in automation and industrial control. Part of the S100 miniature series, this sensor combines a small housing with a fixed optical setup to detect presence or absence of targets by measuring reflected light. Its compact dimensions and multiple mounting options make it suitable for conveyor lines, packaging machines and other automated equipment where non-contact detection is required.

Advantages

The sensor’s miniature 20 x 32 x 12 mm enclosure reduces installation footprint while providing four fixing points (two front threaded holes and two slotted rear holes) for flexible mounting. The fixed adjustment simplifies commissioning and prevents accidental tampering. Integrated ASIC electronics enable programmability and IO-Link communication for remote configuration, dual output channels and stable digital signalling without jitter during communication. Available contrast sensing models provide fast and precise detection of marked or contrasting surfaces.

Suitable for

• Part presence detection on conveyor systems
• Object detection in packaging and labelling machines
• Position sensing on assembly lines and pick-and-place equipment
• Contrast detection for printed marks and labels

Key specifications

• Sensor type: diffuse-mode photoelectric sensor (reflective detection)
• Series: S100 miniature family
• Housing dimensions: 20 x 32 x 12 mm
• Mounting: two threaded holes on the front and two slotted holes on the rear
• Output: dual output channels with digital communication via IO-Link
• Control electronics: integrated ASIC for programmability and stable signalling
• Adjustment: fixed optical setup (no manual sensitivity adjustment)
• Available variants: contrast sensing models for detection of marked surfaces

How to use

Mount the sensor on the machine frame using the provided fixing holes so the sensing face is aligned with the target path. Connect power and signal wiring according to the machine control specifications and configure output behaviour via IO-Link if remote setup is required. Position the sensor at a distance appropriate for diffuse-mode detection so the target surface reflects sufficient light to the sensing element. Verify detection by running representative parts through the sensing zone and, if available, use IO-Link to fine-tune parameters or switch to the contrast sensing mode for marked surfaces.

Recommendations

For reliable performance, keep the sensing window clean and avoid direct exposure to intense ambient light sources that may affect reflection-based detection. Use the contrast models for applications with printed marks or low-contrast targets, and prefer IO-Link configuration when frequent parameter changes or remote diagnostics are required.
