Photoelectric Contrast sensors S8 Series

Datasensing S8 Series

The S8 Series delivers a premium family of compact cubic photo-electric sensors, engineered for tight-space installation, versatile optical modes, and industry-grade reliability. With optical variants covering background suppression on transparent materials, high-resolution contrast detection, laser-spot precision and stainless-steel wash-down ruggedness, the series provides exceptional flexibility, superior detection of difficult targets, and robust performance in harsh or hygienic environments.

Design & Functionality

• The housing size is extremely compact (14 × 42 × 25 mm) enabling installation in space-constrained machine frames, conveyor side-channels or tight packaging modules.
• Optical mode variants include:
  • Background-suppression models for transparent or reflective objects (e.g., film, bottles, shiny surfaces).
  • Contrast sensors capable of switching frequencies up to ~25 kHz for mark detection and ultra-fast applications.
  • Laser-spot models with extremely focused beam (< 1 mm) for micro-part detection and high precision.
  • Stainless-steel housing versions with IP69K protection for heavy-wash, food & pharma or harsh industrial environments.
• Connectivity & control: IO-Link parametrisation, selectable outputs (PNP/NPN/PP), teach-in or trimmer adjustment, delivering smart integration into Industry 4.0 systems.
• Mechanical/Environmental robustness: Many models carry an IP67 or IP69K rating, making them suitable even in wash-down zones or high-hygiene applications.

Total Crossed Beams

(In this context, this term is used to indicate that the sensor delivers consistent detection coverage across its sensing field rather than literal crossed optical beams.)

• The S8 Series ensures a stable detection zone even when mounted in tight frames or when detecting small, shiny, transparent or fast-moving objects — resulting in fewer missed detections, higher repeatability, and better performance in automated systems.
• This reliability is particularly valuable for packaging lines, food & beverage machines, bottle handling, transparent film detection and other high-precision automation contexts.

Beam Pitch Options

(Here interpreted as variant options for sensing distance / optical mode rather than literal beam spacing.)

• Example: Through-beam variants up to ~25 m span.
• Example: Retro-reflective for transparents (coaxial) up to ~0.8 m (or ~2 m for certain laser/transparent variants).
• Example: Background suppression ~50…300 mm (LED) or ~20…200 mm (Class 2 Laser) for challenging transparent/shiny detection. 
• These variant options allow you to select an S8 model matched to your target size, mounting distance, background conditions and throughput requirements — offering design flexibility.

Intrinsic Synchronism

• The electronics and optics are fully integrated within the same housing — no external synchronising modules are required — simplifying installation and reducing wiring complexity.
• With built-in trimmers, status LEDs and standard footprint across variants, setup, calibration and maintenance are streamlined.

Operational Advantages

• Compact footprint with high performance: Despite its miniature size, the S8 Series handles difficult detection tasks such as transparent packaging, shiny bottles, tiny parts and high-speed conveyors.
• Versatile optical modes in one family: From contrast mark detection, background suppression, laser-spot precision, to long-span through-beam, the S8 line provides multiple application-ready modes.
• Cutting-edge connectivity and diagnostics: With IO-Link, dual-channel outputs, selectable logic and fast switching (up to ~25 kHz), the series supports modern automation and Industry 4.0 readiness.
• Industrial & hygienic readiness: With IP67/IP69K stainless-steel options, the S8 is suitable for food, beverage, pharma and other demanding production environments.
• Applications: Ideal for food & beverage packaging lines, transparent film detection, electronics assembly, conveyor presence/absence, high-speed part counting, and any system where space-limited installation, fast detection, and reliable sensing of challenging targets are required.
