Photoelectric Cylindrical sensors FAL Series

Datasensing FAL Series

The FAL Series offers high-performance photoelectric detection using laser emission in an M18 cylindrical format, engineered for a wide variety of industrial applications. With models that span diffuse-reflection, retro-reflective (including transparent object detection), background-suppression and through-beam optical principles, these sensors deliver versatile object detection, long detection ranges, and industrial-grade reliability. 

Design & Functionality

• The series supports 10…30 V DC power supply and is housed in an M18 × 1 body—ideal for standard machine mounts. 
• Emission by visible red laser (650 nm class 1) ensures precise targeting and long-range detection. 
• The housing offers IP67 protection, and protection electronics include reverse-polarity and short-circuit auto-reset—ensuring robust operation in industrial environments. 
• Nominal sensing distances vary widely depending on the optical principle—for example ~300 mm in a diffuse model and up to ~20 m in a through-beam model. 
• Switching frequencies up to ~800 Hz (for diffuse versions) or ~1 kHz for long-range models enable fast detection in dynamic automation systems. 

Total Crossed Beams

(In this photoelectric context, the term translates to a stable and complete detection beam path rather than literal crossed optical beams.)

• The FAL Series maintains a consistently strong detection beam, enabling detection of objects regardless of background or alignment variation.
• This results in reliable, repeatable detection and fewer missed triggers or false-positives in high-throughput manufacturing or packaging systems.

Beam Pitch Options

(Here interpreted as selectable nominal sensing distances and optical configurations rather than literal beam pitch.)

• Diffuse-reflection models: e.g., nominal sensing ~300 mm (white target) for the FAL4/BP-0E variant. 
• Background-suppression (BGS) models: e.g., nominal sensing ~150 mm, blind-zone ~30 mm, switching ~1.5 kHz. 
• Through-beam / receiver models: e.g., nominal sensing ~50 m for FALD series. 
• The variety of models allows selection of sensor based on target size, distance, background reflectivity and mounting clearance—offering flexibility in installation.

Intrinsic Synchronism

• The electronics are fully self-contained, meaning no external synchronisation wiring is required—making installation simpler.
• Time before availability (after power-up) is ≤ 200 ms in many models.

Operational Advantages

• Versatile Optical Principles: With diffuse, retro-reflective, BGS and through-beam models, the FAL Series adapts to many application scenarios from short-range part detection to long-range presence sensing.
• High Precision & Long Range: Laser emission, high switching speeds, and reliable beam stability provide accurate detection across different target types and distances.
• Industrial-Grade Build: M18 housing, IP67 protection, robust materials and built-in protection electronics ensure dependable operation in factory environments.
• Applications: Ideal for conveyor object detection, packaging lines, long-range presence detection, transparent object sensing, machine-tool automation and general manufacturing where precise detection, industrial durability, and versatile mounting are required.
