Photoelectric Fiber optic amplifiers FY Series

Datasensing FY Series

The FY Series offers a versatile family of slot (fork) photo-electric sensors, engineered for precise detection through the slot aperture, fast switching, and flexible mechanical configuration. With variant slot widths from ~5 mm to ~120 mm, minimum detectable object/gap performance down to ~0.1 mm in high-resolution variants, and switching frequencies up to several kHz, this series delivers exceptional precision, high throughput, and adaptability to a wide range of applications.

Design & Functionality

• The sensors come in multiple slot widths and depths, enabling detection of small parts, labels or gaps passing through fork apertures of various sizes.
• Optical and operational highlights include:
  • Ultra-fine detection capability – in high-resolution variants the minimum detectable object/gap may be ~0.1 mm, enabling detection of very narrow labels or film edges.
  • High switching speed – variants support switching frequencies in the kHz range for rapid part or gap detection in fast-moving production lines.
  • Selectable logic (PNP or NPN) and Light-On/Dark-On modes allow flexible integration into diverse automation systems.
  • Robust housing options (metal or polymer) and mounting flexibility make the FY series suitable for machine-side installation in packaging, labelling and conveyor systems.

Total Crossed Beams

(In this context, “Total Crossed Beams” indicates that the sensor offers full detection coverage through the slot aperture rather than literal crossed beams.)

• The FY Series ensures a stable detection zone across the full slot width, so that objects or gaps passing through, whatever their exact position, are reliably detected — reducing missed detections and improving repeatability.
• This is especially beneficial when parts move unpredictably through the aperture or when mounting tolerances are limited, ensuring consistent performance in automated environments.

Beam Pitch Options

(Here interpreted as variant options of slot width / depth / detection resolution rather than literal beam spacing.)

• Example variant: Narrow slot (~5–10 mm) for very small parts or labels.
• Example variant: Mid-slot (~30–60 mm) for standard parts or web gating.
• Example variant: Wide slot (~80–120 mm) for larger assemblies or films.
• These variant options allow you to choose an FY model that matches your part width, gap size, mounting clearance and throughput requirements — providing design flexibility.

Intrinsic Synchronism

• The emitter, detector and electronics are integrated in the same sensor housing — no external synchronising modules required — simplifying wiring and reducing installation complexity.
• With built-in sensitivity adjustment (via trimmer or teach-in depending on variant), LED status indicators and compact footprint, the FY series supports fast commissioning, easy maintenance, and reliable long-term performance.

Operational Advantages

• Ultra-fine gap/part detection: With minimum detectable object/gap down to ~0.1 mm in certain models, the FY Series excels in applications requiring fine resolution (labels, films, webs).
• High-throughput readiness: With switching speeds in the kHz range, the sensors keep up with fast conveyor speeds and high-speed packaging or web lines.
• Flexible slot geometry: With multiple slot widths and depths, the series adapts from small-part detection to large web/film applications.
• Industrial compatibility: Selectable logic/output types, robust housing, and flexible mounting make the FY sensors suitable for machine-side mounting in labelling machines, packaging lines, film/gap detection modules and more.
• Applications: Ideal for label edge detection, continuous film gap monitoring, transparent web detection, part or sheet presence through a fork, registration mark detection in packaging conveyors, and any scenario where a slot-sensor format, high resolution, and fast reliable detection are required.
