Photoelectric Cubic sensors S45 Series

Datasensing S45 Series

The S45 Series presents a versatile family of miniature photo-electric sensors, engineered for tight-space installations, versatile optical modes, and industrial robustness. With models spanning from diffuse proximity (~800 mm), background suppression (~400 mm), polarized retro-reflective (7 m LED / 15 m Laser) and through-beam (15 m LED / 20 m Laser) in a compact body, the series offers exceptional flexibility, compact design, and robust functionality.

Design & Functionality

• The housing is extremely compact (12 × 34 × 20 mm) enabling installation in very confined machine frames, conveyor side-tags or automation modules.
• Optical mode variants include:
  • Diffuse-proximity models with nominal sensing distances up to ~800 mm in LED versions.
  • Background suppression models nominal ~400 mm (LED) allowing detection near backgrounds. 
  • Polarized retro-reflective models up to ~7 m (LED) or ~15 m (Laser) for reflector-type detection. 
  • Through-beam emitter/receiver models with spans up to ~15 m (LED) or ~20 m (Laser) for long-distance detection. 
• Switching frequency up to ~1 kHz and response time ~0.5 ms typical — enabling fast and reliable detection. 
• Logic outputs: Selectable NPN/PNP, Light-On or Dark-On via Teach-in, with remote-teach input for rapid setup. 
• Protection rating of IP67 & IP69K, making the S45 Series suitable for wash-down, dust-prone, or harsh industrial environments. 

Total Crossed Beams

(In this series context, this means the sensor ensures consistent detection coverage across its sensing zone rather than literal crossed optical beams.)

• The S45 Series delivers a stable detection zone across tight mounting spaces and varied target/background conditions — resulting in fewer missed detections and higher repeatability in automated systems. 
• This reliability is particularly valuable in conveyors, packaging lines, electronics assembly or automotive-industry setups where mounting clearance is minimal but detection reliability cannot be compromised.

Beam Pitch Options

(Here interpreted as selectable sensing-distance / optic-variant options rather than literal beam spacing.)

• Example: Diffuse proximity ~800 mm nominal (LED).
• Example: Retro-reflective up to ~7 m (LED) or ~15 m (Laser).
• Example: Through-beam up to ~15–20 m span.
• These options enable selection of an S45 model matched to target size, mounting clearance, background conditions and required span — delivering design flexibility.

Intrinsic Synchronism

• The electronics and optics are all integrated into one compact housing — no external synchronisation modules or special wiring are required — simplifying installation and reducing commissioning time.
• With built-in Teach-in, remote-teach input and LED-indicators (power, stability/output), the setup is efficient and diagnostics are simplified.

Operational Advantages

• Compact footprint with high capability: The S45 Series offers long-detection spans and multiple optical modes in a miniature housing — ideal for automation, packaging and tight-space applications.
• Versatile optical modes in one family: Diffuse, background suppression, retro-reflective, through-beam, laser and LED options all in the same series — reducing the need to maintain multiple sensor stock lines.
• Industrial robustness: Designed with IP69K rating, rugged housing, remote-teach input and high switching speeds, the S45 is built for demanding environments.
• Applications: Excellent for conveyor presence detection, transparent film detection, small part detection in electronics, packaging line quality assurance, and setups where compact installation, long span detection, and high reliability are required.
