Photoelectric Cylindrical sensors DM Series

Datasensing DM Series

The DM Series provides flexible and robust photoelectric sensing for a wide range of industrial applications. With models covering diffuse reflection, polarized and through-beam detection principles, the series delivers versatile object detection, adjustable operation, and industrial-grade protection to suit general manufacturing, packaging, intralogistics and automation environments.

Design & Functionality

• Available in M12 cylindrical form factor, the series supports multiple optical principles including diffuse-reflection (short distance), polarized, and through-beam configurations, enabling adaptation to a wide range of target types and installation formats. 
• Equipped with local and remote Teach-in functions, and Light-ON / Dark-ON selectable outputs, enabling quick configuration on-site and flexible switching logic for varied automation needs.
• Protection rating of IP67, with full electrical protection (reverse-polarity, short-circuit auto-reset) and rugged housing materials, ensures reliable operation in harsh environments. 
• Example spec: A diffuse-reflection model offers a nominal sensing distance of 100 mm, repeat accuracy ≤ 5%, thermal drift of Sr ≤ 10%, switching frequency ~400 Hz and response time ~1.25 ms. 

Total Crossed Beams

(In this photoelectric sensor context, this concept translates into consistent detection field and reliable signal even when installation or alignment varies.)

• The DM Series maintains a stable detection field, meaning that even in short-distance or reflection-type installations the sensor delivers repeatable detections and is less affected by slight misalignment or target variation.
• This ensures fewer missed detections in automation systems where targets may vary or clearance is limited.

Beam Pitch Options

(Here interpreted as selectable sensing distances / optical configurations rather than literal beam spacing.)

• Diffuse-reflection models have shorter sensing ranges (for example ~100 mm) while through-beam models offer longer distances. 
• Models support metal or non-metal targets, background filtering and selectable output logic, giving flexibility in machine design and integration.
• The ability to select “Light-ON” or “Dark-ON” switching further enhances adaptability to different application requirements.

Intrinsic Synchronism

• The series integrates its electronic control and switching logic, so no external synchronisation wiring or complex timing setup is needed — simplifying installation.
• With fast response times (for example ~1.25 ms) and moderate switching frequencies (~400 Hz) in many models, the DM Series is suitable for dynamic automation systems.

Operational Advantages

• Flexible Sensing Principles: With diffuse, polarized and through-beam options, the DM Series can be applied to many target types—from reflective surfaces, clear objects to larger opaque parts.
• Quick Configuration & Integration: Teach-in, selectable output modes, and standard M12 housing make installation and commissioning faster and simpler.
• Industrial Protection & Reliability: IP67 rating and full electrical protection suite ensure the sensor performs reliably in production environments with dust, moisture or mechanical stress.
• Applications: Ideal for conveyor and sorting systems, packaging machines, part-presence detection in general manufacturing, electronics assembly, intralogistics and wherever object detection flexibility, industrial robustness and compact M12 mounting are required.
