WS2811 RGB Square Pixel String (12 V DC) – 12 mm lay-flat, 10 cm pitch, IP68

Addressable RGB pixel string with WS2811 data signal (single-wire NZR) for 12 V installations. The square / lay-flat housing is designed for flush mounting on flat materials (e.g. coro/panels, signs, matrix builds): defined orientation, cleaner front appearance and less “twist” in the substrate. For repeatable results, proper power distribution, sensible injection points and a consistent GND reference between controller, PSU and string are essential.

WS2811 – protocol & technical background

WS2811 is a widely used standard for digitally addressable RGB pixels. Data is transmitted as single-wire NZR (typically up to 800 kHz). Each pixel consumes its data (usually 24 bit) and forwards the remaining stream to the next pixel in the chain.

Key specifications

IC / protocol: WS2811, single-wire NZR, up to 800 kHz
Supply: 12 V DC
Pixels: 12 mm square / lay-flat, RGB, individually addressable
Pitch: 10 cm (4") standard
Protection: IP68 (potted pixels)
Wiring: 18 AWG / 0.75 mm²
Mechanics: fits 12 mm mounting holes (panel/coro mounts, pixel panels)

Square / lay-flat: optimized for visible front mounting on flat materials (props, signs, matrix panels) – flush seating and defined orientation reduce visual “noise” in tight rows and matrices.

Options – how to select

Pixel count: 50 or 100
Connector: JST-SM or xConnect® (match your system/extensions)
Cable color: black or blue/white/red (per option)
Special lengths: project-based / on request

Note: IP68 applies to the potted pixels. For a truly weatherproof system, connector sealing and mechanical strain relief also matter.

Electrical planning (current, voltage drop, injection)

Planning current: up to approx. 60 mA per pixel at full white (RGB 100%)
Example load: 50 px ≈ 3.0 A · 100 px ≈ 6.0 A
PSU headroom: typically +20–30%
Voltage drop: depends on cable length, gauge, topology and acceptable drop
Power injection: define points based on measurements/drop, not guesswork

Rule of thumb: ΔU = I · R (consider both forward and return path). In practice: measure voltage under load at the start and end of a segment and derive injection points from that.

WS2811 data signal & integration

Signal: single-wire NZR; daisy-chain (pixel consumes data and forwards)
GND reference: common ground between controller/injection/string is mandatory
Controller → first pixel: keep as short as possible; on longer runs buffering/conditioning is common
Direction: follow DIN/DO marking/arrow
Topology: segment larger setups for power; route data according to controller capabilities

Outdoor & connector systems

Pixels are IP68 (potted). For permanent outdoor installs, the connector system and mechanics also matter. xConnect® is typically designed for robust outdoor connections. JST-SM is common, but outdoors it usually needs additional sealing (e.g. heat-shrink/gel/housing) and strain relief depending on the build.

FAQ

How long is a string with 10 cm pitch?

Roughly: 50 pixels ≈ 5 m, 100 pixels ≈ 10 m (plus lead wires – depending on option).

When do I need power injection?

When voltage drop becomes visible under load (brightness/color shift) or measurements at the end of a segment drop too far. Define injection points by measuring under load.

Why square / lay-flat instead of bullet?

Square / lay-flat pixels are optimized for flat-panel mounting (coro/panels, signs, matrix panels): flush seating, defined orientation and typically a cleaner front appearance in rows/matrices.

Which connector should I choose – JST-SM or xConnect®?

Choose based on your controller/extension system. For robust outdoor connections, xConnect® is typically the better choice. Outdoors, JST-SM usually requires extra sealing and strain relief.

What should I check first if there is flicker?

1) common ground (GND) between controller/injection/string, 2) data direction (DIN/DO), 3) voltage under load at the start (and end if needed), 4) long data leads/EMI – add buffer/conditioning if required.
