Photoelectric Cubic sensors S6 Series

Datasensing S6 Series

The S6 Series delivers a fully-featured family of compact 50×50 mm photo-electric sensors, engineered for versatile installation, broad detection spans, and industrial reliability. With versions ranging from short-range diffuse (~900 mm), background suppression (~30-250 mm), retro-reflective (~0.1-6 m), up to through-beam spans of ~20 m, the series provides exceptional flexibility, flexible power supply options, and robust performance.

Design & Functionality

• The series uses a compact cubic 50×50 mm housing, allowing easy mounting even in constrained machine spaces or conveyor side-frames.
• Optical mode variants include:
  • Diffuse-reflection models with nominal sensing distances from ~900 mm up to ~2 m depending on version. 
  • Background suppression (BGS) models with nominal ranges ~30-250 mm, for reliable detection close to background surfaces. 
  • Polarised retro-reflective variants reaching nominal distances up to ~5-6 m (on R2 reflector) depending on model. 
  • Through-beam (emitter/receiver) models with nominal sensing distances up to ~20 m in certain versions. 
• Supply voltage options allow broad compatibility: Free-voltage AC/VDC versions with relay output, or 10-30 V DC versions with transistor (NPN/PNP) outputs — enabling flexible power integration. 
• Output logic includes selectable Light-On / Dark-On, NPN or PNP logic (in DC versions) and NO/NC contacts (in relay versions) — offering control flexibility. 
• Protection rating IP65, housing material ABS, mounting dimensions ~18×50×50 mm (body depth approx ~18mm) – giving industrial-grade robustness. 

Total Crossed Beams

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

• The S6 Series ensures a stable detection zone across its wide range of optical modes and spanning distances, meaning fewer missed detections and improved reliability on conveyor lines, packaging equipment and automated machines.
• This reliability is critical when targets, backgrounds or installation clearances vary.

Beam Pitch Options

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

• Example: A diffuse proximity variant with nominal sensing distance ~900 mm. 
• Example: A retro-reflective variant with nominal span up to ~6 m on reflector. 
• Example: A through-beam variant with nominal sensing distance up to ~20 m. 
• These variant options allow selection of an S6 model that matches target size, mounting clearance, background conditions and span — providing design flexibility.

Intrinsic Synchronism

• The electronics and optics are fully integrated in the housing — no external synchronisation modules or special wiring are required — simplifying installation and maintenance.
• With built-in trimmers, LED indicators (for power, output/stability) and sensitivity adjustment, setup and commissioning are streamlined — saving installation time.

Operational Advantages

• Universal detection capability: With diffuse, BGS, retro-reflective and through-beam modes in one family, the S6 Series covers a wide spectrum of applications, reducing the need for multiple sensor types.
• Compact form-factor: The 50×50 mm housing allows installation even in tight machine frames, conveyor side-tags or compact automation modules.
• Flexible power and output: Compatibility with AC/VDC or 10-30 V DC supplies, selectable logic and output modes make integration into diverse control systems straightforward.
• Robust in industrial conditions: IP65 protection, ABS housing, standard trimmer controls and diagnostic LEDs support reliable operation in manufacturing, packaging lines, transport systems and logistics.
• Applications: Ideal for automatic machines, packaging conveyors, transportation lines, warehouse automation, presence/absence detection across spans and background-rich zones — i.e., situations where versatility, compact mounting, and reliable detection are required.
