Photoelectric Cubic sensors SM123 Series

Datasensing SM123 Series

The SM123 Series offers a sophisticated family of miniature photo-electric sensors, engineered for space-constrained installation, versatile detection modes, and industrial reliability. This series supports detection of small parts and high-speed objects in compact machine layouts, providing exceptional speed, high repeatability, and robust performance.

Design & Functionality

• The housing is extremely compact, enabling mounting in very tight machine frames, conveyor side-channels or confined automation modules — making the SM123 ideal where traditional sensors cannot fit.
• Optical variants & features include:
  • Models with high switching speeds to support fast moving targets and high throughput automation.
  • Selectable Light-On / Dark-On logic and NPN or PNP outputs for flexible integration into different control systems.
  • Built-in alignment/diagnostic LED indicators allowing quick commissioning and status checks.
• The housing delivers industrial protection rating (dust and splash resistant) and is built from durable materials suited to automation environments — meaning the SM123 withstands challenging production conditions while maintaining performance.

Total Crossed Beams

(In this context, this refers to the sensor providing consistent detection coverage across its target zone rather than literal crossed optical beams.)

• The SM123 Series ensures a stable detection zone even when mounted in very confined spaces, with targets moving at high speed or appearing at varied positions within the sensing field — resulting in fewer missed detections and greater reliability in automated systems.
• Its compact form, high-speed capability and flexible logic make it ideal for integration into packaging modules, electronics assembly lines, and sorting conveyors where space is at a premium and throughput demands are high.

Beam Pitch Options

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

• Example variant: Short-range diffuse or background suppression models tailored to detect small parts close to machine frames.
• Example variant: Longer-range models (within miniature footprint) providing enhanced flexibility for installation distances and background conditions.
• These variant options allow you to select an SM123 model that matches your target size, mounting clearance, background reflectivity and speed requirements — offering design flexibility.

Intrinsic Synchronism

• The electronics and optical module are fully integrated within the compact housing — no external synchronisation modules or additional wiring are required — simplifying installation and reducing commissioning effort.
• With a small form-factor and built-in diagnostic feedback (LEDs/trimmers), setup is rapid, maintenance is minimal and reliability is enhanced.

Operational Advantages

• Miniature footprint with full performance: The SM123 Series delivers high switching speeds and flexible optical variants in a very small housing — making it suitable for space-limited automation systems.
• Flexible logic & mounting: Selectable NPN/PNP logic, multiple output configurations, and compact mechanical design support integration into diverse machine control architectures.
• High-throughput ready: With fast response and switching capability, these sensors can keep up with high-speed conveyors, pick-and-place machines, and automated packaging lines.
• Robust construction: Designed for industrial automation with protective housing, easy mounting, and reliable operation even in demanding environments.
• Applications: Ideal for electronics assembly, packaging machine detect-presence/absence, conveyor object detection in limited space, sorting modules and any application requiring compact installation, high speed, and reliable detection.
