Photoelectric sensor Datalogic S3Z, black, IP67, 2 kHz frequency, 50 g

Datalogic S3Z is a compact photoelectric sensor designed for industrial presence detection and object sensing. The sensor comes in a black housing with IP67 protection against dust and water and has a lightweight design of approximately 50 g. With a switching frequency of 2 kHz and standard three‑wire output configuration, the S3Z family supports typical conveyor monitoring, machine automation and basic sensing tasks that require reliable, sealed sensors. Available optics and emission options cover polarized, diffused, background suppression and through‑beam versions to match common sensing needs.

Advantages

The S3Z sensor offers sealed IP67 protection for use in dusty or wet industrial environments while remaining compact and lightweight for installation in constrained spaces. A 2 kHz switching frequency enables responsive detection of moving objects, and standard three‑wire wiring simplifies integration with existing control systems. Multiple optical functions and emission types provide flexibility for transparent object detection, background suppression and long‑range through‑beam applications. Interference prevention makes it possible to mount two units side by side without cross‑talk issues.

Suitable for

• Conveyor belt item detection and counting
• Machine automation proximity and presence sensing
• Transparent object detection (polarized models)
• Short to medium range sensing in compact assemblies

Key specifications

• Protection rating: IP67 (dust tight and water resistant)
• Switching frequency: 2 kHz
• Weight: approximately 50 g
• Output configuration: standard three‑wire
• Optical functions available: polarized, diffused, background suppression, retro‑reflective and through‑beam
• Emission options: LED or LASER depending on model
• Detection ranges vary by model: short to long range options (polarized for transparent detection, diffused and through‑beam available)
• Designed for side‑by‑side mounting with interference prevention

How to use

Mount the sensor in a position where the sensing axis aligns with the target area and where the selected optical function matches the detection task (for example, polarized models for transparent objects or through‑beam for long‑range detection). Connect the sensor using the standard three‑wire configuration to your control input, observing correct power and output polarity as specified by the manufacturer's wiring instructions. Adjust the sensor position and, if provided by the model, fine‑tune sensitivity or alignment to achieve reliable switching at the required object speed. Verify operation at the intended switching frequency and test for stable detection under normal operating conditions.

Recommendations

Select the optical function and emission type that match your application: polarized for transparent materials, background suppression for close background‑contrasted targets, and through‑beam or retro‑reflective for longer ranges. Ensure sealing integrity when installing in wet or dusty environments and allow sufficient clearance for alignment and service access. When mounting multiple sensors nearby, rely on the model's interference‑prevention capability but perform installation tests to confirm consistent behavior in your specific setup.
