WS2811 RGB Pixel String (5 V DC) – 12 mm Bullet, 10 cm Pitch, IP68

Addressable RGB pixel string using WS2811 data (single-wire NZR) for 5 V installations. In 5 V systems, clean results depend primarily on power distribution, power injection and a solid GND reference.

WS2811 – protocol & technical basics

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

Core specifications

Chip/protocol: WS2811, single-wire NZR, up to 800 kHz
Supply: 5 V DC
Pixels: 12 mm bullet, RGB, individually addressable
Pitch: 10 cm (4") standard
Protection: IP68 (potted pixels)
Wiring: 18 AWG / 0.75 mm²
Mechanics: fits 12 mm mounting holes (typical pixel mounts/plates)

Variants – selecting the right option

Pixel count: 50 or 100
Connector: choose to match your system (JST-SM or xConnect®)
Cable color: per variant
Custom lengths: project-based / on request

Note: IP68 applies to the potted pixels. Outdoor readiness of the full assembly also depends on connector sealing and strain relief.

Electrical planning (current, voltage drop, power injection)

Planning current: up to ~60 mA per pixel at 100% white (RGB full)
Example load: 50 px ≈ 3.0 A · 100 px ≈ 6.0 A
PSU headroom: typically +20–30%
Voltage drop: becomes relevant faster at 5 V due to higher current (run length / gauge / topology)
Power injection: derive injection points from measurements/ΔU, not guesswork

Rule of thumb: ΔU = I · R (include both supply and return). In practice, measure voltage under load at the segment start and end.

WS2811 data signal & system integration

Signal: single-wire NZR; daisy-chain (pixel reads data and forwards the rest)
GND reference: shared ground between controller, injection and string is mandatory
Controller → first pixel: keep as short as possible; long runs often require buffering/signal conditioning
Direction: observe DIN/DO marking/arrow, otherwise the string will not respond
Topology: structure larger builds into power segments; route data per controller requirements

Test setup: start at 20–30% brightness, then increase step by step. This helps separate power issues (ΔU) from signal issues.

Outdoor & connector systems

Pixels are IP68 (potted). For long-term outdoor installations, the connector system and mechanics matter as well. xConnect® is typically designed for robust outdoor plug connections. JST-SM is common in compact setups, but outdoors it usually needs additional sealing (heat shrink/gel/housing) and strain relief.

FAQ

How long is the string at 10 cm pitch?

At 10 cm (4") pitch, length mainly depends on pixel count: 50 pixels ≈ 5 m, 100 pixels ≈ 10 m – plus lead wires (variant-dependent).

When do I need power injection at 5V?

When voltage at the end of a power segment drops too far under load (visible dimming/colour shift) or measurements indicate it. Key factors: pixel count, brightness, cable runs, gauge and topology. Best practice: measure under load and place injection points accordingly.

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

Choose the connector that matches your controller/extension ecosystem. For plug-and-play outdoor connections, xConnect® is typically the robust option. JST-SM usually requires additional sealing and strain relief for outdoor use.

What should I check first if the string flickers?

1) shared GND between controller/injection/string, 2) direction (DIN/DO), 3) voltage under load at the first and last pixel, 4) controller-to-first-pixel run (too long) and signal conditioning.
