Photoelectric Cubic sensors FG Series

Datasensing FG Series

The FG Series provides a robust family of cubic photo-electric sensors engineered for high-range detection, compact form-factor installation, and industrial reliability. With models covering emitter/receiver (E+R), polarized reflex, background suppression and long-span detection up to 50 m, the series delivers versatility in application, selectable logic/output types, and vehicle-factory grade durability.

Design & Functionality

• The FG series uses a cubic housing (typical dimensions ~20 × 44.9 × 60 mm) in an ABS body rated for industrial environments and equipped with M12 connector or cable.
• Optical modes include: emitter-receiver up to ~50 m range; polarized reflex up to ~12 m; background-suppression models (~310 mm to ~600 mm) ensuring detection of objects in front of backgrounds.
• Output and supply variations: DC models (10-30 V) with NPN or PNP and Light/Dark selector; AC/DC relay versions (24-240 V) with NO+NC outputs.
• Sensitivity adjustments via a 2-turn potentiometer give fine-tuning for target/background differentiation; dual-LED indicators (green power, yellow output) assist alignment and diagnostics.
• Protection rating is IP67, enabling installation in dusty or damp environments; full electrical protections (reverse polarity, short-circuit reset) support industrial reliability. 

Total Crossed Beams

(Interpreted here as consistent and reliable detection coverage rather than literal crossed beams.)

• The FG Series ensures a stable detection field across its various optical modes — whether short-span background suppression or long distance emitter/receiver — reducing false/no-detection events even with changing backgrounds, reflections or target types.
• This reliability is critical for applications where high throughput, variable target presentation or long span detection are required (e.g., conveyor systems, robot feeders, large machine cells).

Beam Pitch Options

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

• Example background suppression variant: nominal sensing distance ~310 mm or ~600 mm on white (Kodak 90%) target. 
• Example polarized reflex variant: up to ~12 m on reflector sheet. 
• Example emitter-receiver variant: up to ~50 m sensing range. 
• These varied sensing spans allow you to select a model based on target size, mounting clearance, background conditions and span — providing design flexibility.

Intrinsic Synchronism

• The electronics are fully integrated — no external synchronisation wiring or modules needed — simplifying installation and maintenance.
• The rapid response times (e.g., 500 µs in emitter/receiver models) and ability to fine-tune threshold via potentiometer mean the sensor can be optimised for fast moving objects and varied backgrounds. 

Operational Advantages

• Long-span detection in compact housing: With detection distances up to 50 m in some variants, the FG series supports large-machine or conveyor spans while retaining compact sizing.
• Flexible output logic and supply voltage: With options for NPN/PNP, NO/NC, AC or DC supply, these sensors integrate into varied control systems without needing major changes.
• Easy commissioning and diagnostics: Potentiometer adjustment, LED status indicators and standard housing aid quick setup and reliable alignment.
• Industrial-grade durability: IP67 protection, rugged ABS housing, high ambient-light immunity (up to 10,000 lux sunlight) reduce risk of failure in challenging environments. 
• Applications: Ideal for conveyor presence detection, robot cell part verification, long-span emitter/receiver installations, background-rich detection (e.g., reflective surfaces, dark targets), and automation systems where compact mounting, long reach, and versatile detection are vital.
