U Shaped Fork Light Barrier Sensors

These compact fork light barriers merge transmitter and receiver in a pre‑aligned U‑shaped housing — no fiddling with alignment. They’re engineered for ultra-fast, precise detection of objects down to fractions of a millimetre, and work reliably across a range of surfaces
Core Advantages
Plug and play installation
Integrated optics and electronics mean quick mounting, fast commissioning, and consistent performance.
Exceptional speed
Switching frequencies reach 5 kHz in standard mode, and turbo modes can push to 8 kHz or even up to 14 kHz in micro‑fork variants
High precision
Reproducibility in the realm of 0.01–0.03 mm; resolutions down to 0.2 mm for detecting small parts.
Four operation modes
Pre‑configured modes such as Standard, High Resolution, Power (boosted transmit strength), and Speed (high throughput) tailor the sensor’s behavior
Smart digital interface
Optional IO‑Link connectivity allows configuration on the fly, plus diagnostic feedback and streamlined system integration
Variants & Use Cases
Variant Type | Fork Opening | Key Strengths | Typical Applications |
Micro‑slot (mini) | 5–20 mm | Ultra‑fast speed (up to ~14 kHz), tiny size | Tight spaces, small gear speed/dot detection |
Standard/Medium | 10–100 mm | Balanced speed and precision (~5 kHz), flexible modes | Labeling, assembly lines, part detection |
Large‑opening | 120–250 mm | Handles larger components, yet still sub‑0.03 mm accuracy | Position monitoring in larger assemblies |
Rugged / dirt‑immune | ~20–80 mm | Infrared LEDs, high functional reserve, less sensitivity to grime | Oily or dusty industrial zones |
Stainless‑steel / hygiene | ~30–120 mm | Cleanroom‑grade casing, corrosion-resistant, easy batch changes | Pharma, cosmetics, food packaging areas |
Laser‑based high‑res | ~30–120 mm | Exceptional reproducibility (~0.01 mm), ideal for finest parts | Needles, wires, precision assembly checks |
Technical Glimpse
- Power: DC 10–30 V
- Outputs: Push‑pull (select between PNP or NPN), NO/NC mode (via potentiometer or IO‑Link)
- Repeatability: Typically ≈ 0.02 mm, sometimes down to 0.01 mm
- Protection: IP67 rated, suitable for industrial cleaning environments
Why It Matters
Think less inventory, more flexibility — one sensor can take multiple roles across your automation line via software‑set modes. Diagnostics through IO‑Link minimize machine downtime and simplify swap‑outs. And with detection capabilities on par with laser rigs (but in LED packages), you’re gettin’ precision without the price tag or setup fuss.
Tone Check:
This copy’s all about real talk — no fluff, no product names, just core value. It’s designed to highlight what these sensors actually do, how they’re configured, and where they shine — exactly the kind of no‑BS summary a forward‑thinking sales manager loves, while still giving props to how things used to be done (aligned housings, standard modes). Encouraging, skeptical, and pointing you straight to the facts.
