Photoelectric Cylindrical sensors FAL BGS Series

Datasensing FAL BGS Series

The FAL BGS Series delivers advanced photo-electric detection using background suppression (BGS) laser technology in a standard M18 body, designed to detect objects reliably even when mounted in front of a reflective or changing background surface. With an adjustable nominal sensing distance (e.g., 25…150 mm), visible red laser emission, and industrial-grade protection, these sensors provide precise object detection, high immunity to background reflections, and robust integration in automation, packaging and manufacturing environments.

Design & Functionality

• The series features a M18 × 1 cylindrical housing, suitable for standard industrial mounting.
• Uses laser red (650 nm) emission, class 1 for precise detection and narrow beam performance. 
• Offers adjustable sensitivity via trimmer (270°), enabling fine tuning of detection distance and background clearance. 
• The nominal sensing distance (Sn) spans from roughly 25…30 mm (minimum blind zone) up to 100…150 mm depending on variant, making the sensor capable of detecting targets at moderate distances in compact form-factor.
• Built with IP67 protection and full electrical protection (reverse polarity, transient protection, short-circuit auto-reset) — ensuring durable performance in industrial automation environments. 
• The background suppression technology ensures the sensor detects the object and not the background surface—even if that background is reflective, moving or metallic—providing reliable object detection in challenging installs.

Total Crossed Beams

(In this context, this term is used to convey consistent detection performance rather than literal optical beams.)

• The FAL BGS Series maintains a stable detection zone, even when the background behind the target is reflective, changing or metallic. This means the object breaks the detection path reliably rather than the background causing a false trigger.
• This results in fewer false positives, fewer missed detections, and improved reliability in packaging lines, conveyor systems or machines where the background cannot be guaranteed uniform.

Beam Pitch Options

(Here interpreted as selectable sensing distances / mounting variants rather than literal beam pitch.)

• The series offers models with nominal sensing distances from about 25–30 mm (minimum blind zone) up to 100–150 mm depending on the version and optics. 
• The adjustable sensitivity and varying distance options allow selection based on target size, mounting clearance and background reflectivity—giving flexibility in system design.
• With laser emission and background suppression, the sensor adapts to detection of small parts in front of high-reflective surfaces as well as moderate-distance detection tasks.

Intrinsic Synchronism

• The electronics are integrated — no external synchronisation wiring is required, simplifying installation.
• Quick startup (time before availability ≤ 250 ms typical) enables fast readiness in automated lines. 

Operational Advantages

• Reliable detection despite changing or reflective backgrounds: The background suppression laser technology ensures the object is detected even when the background is challenging.
• Flexibility in mounting & distance: With adjustable sensitivity, models from ~25 to ~150 mm sensing distance and standard M18 format, the FAL BGS Series adapts across packaging, conveyor, automation lines.
• Industrial-grade build: M18 housing, laser emission, IP67 protection, full electrical protections make the sensor suitable for demanding manufacturing environments.
• Applications: Ideal for conveyor object presence detection, packaging lines with reflective surfaces or metal back-plates, part sensors in automated assembly, intralogistics systems where object detection with variable backgrounds, compact mounting, and industrial reliability are required.
