SICK HLG2-050F811 Light Grid, 2 mm High-Res Detection

SICK HLG2-050F811 Automation Light Grid — 2 mm Resolution for Flat-Part Detection

SICK HLG2-050F811 automation light grid with 2 mm resolution is built to detect thin, flat items on high-speed lines with dependable repeatability. Its compact 50 mm detection height, fast ~3 ms response, and infrared beam array capture narrow edges and small gaps, even when parts are skewed or slightly overlapping. A rugged aluminum body with protective front screen and IP54 sealing supports daily industrial use, while wide operating temperatures and strong ambient-light immunity maintain stability on brightly lit factory floors. Standard M12 connection and complementary PNP outputs make PLC integration straightforward for counting, presence check, and ejection tasks.

Use SICK HLG2-050F811 to count blister packs, verify PCB panels, detect gaskets or shims, and track labels or foils without mechanical guides that can snag product. The fine 2 mm beam spacing improves pass/fail decisions when tolerances are tight, while rapid response sustains accuracy at higher conveyor speeds. Complementary outputs (Q and /Q) simplify good/reject logic, and cable synchronization keeps transmitter/receiver aligned for stable performance over long shifts. Broad ambient-light immunity reduces nuisance triggers, and the robust housing minimizes recalibration and service intervals—helping production teams maintain throughput, reduce scrap, and shorten commissioning time across packaging and electronics assembly.

Why HLG2-050F811?

Because it sees the “in-between.” The HLG2-050F811’s ultra-fine 2 mm beam spacing and rapid response catch thin edges, tiny gaps, and skewed parts that photoeyes miss. It drops into PLCs via standard M12 and complementary PNP outputs, shrugs off bright factory lighting, and runs day after day in a rugged, compact body that’s built for busy conveyors.

What problem does it solve?

Miscounts, misfeeds, and “vanished” flat parts. When labels, foils, PCBs, or gaskets overlap or arrive off-angle, traditional sensors hesitate. The HLG2-050F811 forms a dense light curtain that resolves small features at line speed, stabilizes detection without mechanical guides, and keeps alignment steady—cutting scrap, false rejects, and downtime while making quality checks and ejection logic wonderfully predictable.

The Applications

1.Blister Pack Counting on High-Speed Cartoners
Cartoning lines often miscount when glossy foil reflects light or when tablets ride slightly overlapped. Mounting an HLG2-050F811 across the infeed creates a dense silhouette of each pocket, so tiny cavities and perforations are resolved at line speed. The fine 2 mm grid captures the true leading edge even when packs skew, while fast response supports short pitch lengths. Complementary outputs plug straight into reject and verification logic, cutting false ejects without adding mechanical guides that can snag film. Robust housing and strong ambient-light immunity keep counts stable during operator inspections and lamp changes, helping quality teams maintain target OEE across frequent format shifts.

2.PCB Panel Presence & Skew Check at Depaneling
Before routing or singulation, machines must confirm a panel is present, fully seated, and aligned. Spanning the conveyor with an HLG2-050F811 forms a crisp profile of thin FR-4 edges, mouse-bites, and break-off tabs. If a panel is offset, bowed, or partially missing, the beam pattern changes immediately and the system halts within milliseconds, protecting tooling from crashes. Cable synchronization maintains stable thresholds despite vibration, and the compact 50 mm detection height slides between fixtures without redesign. The result is fewer broken bits, less dust from emergency stops, and faster restarts—especially valuable on mixed panel sizes common to contract assembly and fast-turn prototypes.

3.Web Handling: Label/Film Splice & Leading-Edge Detection
Clear films and label webs challenge single-point sensors, which often “see through” the material or miss splices. Positioning an HLG2-050F811 across the lane creates a high-contrast shadow of the web, leading edge, and splice gap. The 2 mm resolution distinguishes subtle thickness transitions, enabling precise cut-to-mark timing without mechanical flags or felt wipers that wear out. Rapid response supports tight registration windows on narrow lanes, while immunity to bright task lighting keeps counts steady during maintenance. Converters and packagers gain cleaner cuts, fewer double-wraps, and more accurate roll-end detection—improving changeover speed and reducing scrap when switching between opaque, translucent, and transparent substrates.

4.Flat Mail & Document Sorting on Conveyors
Postal and fulfillment centers handle thin mailers, booklets, and flats that arrive overlapped or skewed, confusing photoeyes and causing misroutes. An HLG2-050F811 forms a narrow detection window over the belt, capturing the precise leading edge of each piece even with glossy coatings or variable thickness. Dual PNP outputs feed diverter timing directly, while the short response time maintains accuracy at higher belt speeds. The compact detection height fits between rollers and requires no bulky guide rails that slow cleaning. Consistent edge detection steadies induct rates, reduces rework at manual stations, and keeps service-level targets intact during peak periods with mixed packaging formats.
