Description

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

Addressable RGB pixel string using WS2811 (single-wire NZR) for 12 V installations. For stable, repeatable results, proper power distribution, sensible injection points, and a continuous GND reference between controller, PSU and string are key.

WS2811 – protocol & technical basics

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 portion of data (typically 24 bit) and forwards the remaining stream to the next pixel in the daisy-chain.

Core specifications

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

Variants – how to choose

  • Pixel count: 50 or 100
  • Connector: JST-SM or xConnect® (match your system/extension wiring)
  • Cable colour: black or blue/white/red (per variant)
  • Custom lengths: project-based / on request
Note: IP68 applies to the potted pixels. For a fully outdoor-ready system, the connector/sealing and mechanical strain relief also matter.

Electrical planning (current, voltage drop, injection)

  • Planning current: up to approx. 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: depends on cable length, gauge, topology and allowed ΔV
  • Power injection: define injection points from measurement/ΔV targets (not “by feel”)
Rule of thumb: ΔV = I · R (consider both outgoing and return conductors). Practical approach: measure voltage under load at the start and end of each power segment and derive injection points from that.

WS2811 data signal & system integration

  • Signal: single-wire NZR; daisy-chain (pixel consumes data and forwards the rest)
  • GND reference: common ground between controller, injection and string is mandatory
  • Controller → first pixel: keep as short as possible; for long runs, buffering/signal conditioning is common
  • Direction: observe DIN/DO (marking/arrow) or the string will not respond
  • Topology: structure larger builds into power segments; route data according to controller design

Outdoor & connectors

The pixels are IP68 (potted). For long-term outdoor installations, the connector system and mechanical build quality are also important. xConnect® is typically designed for robust outdoor plug connections. JST-SM is widely used, but outdoors it usually requires additional sealing (e.g. heat shrink/gel/enclosure) and proper strain relief depending on the installation.

FAQ

How long is a string with 10 cm pitch?
With a 10 cm (4") pitch, the length is primarily determined by pixel count: 50 pixels ≈ 5 m, 100 pixels ≈ 10 m – plus lead wires (depending on variant).
When do I need power injection?
When voltage at the end of a power segment drops too far under load (visible: dimming/unstable colours) or measurements confirm it. Key factors are pixel count, brightness, cable lengths, gauge and topology. Recommendation: measure under load and derive injection points from data.
Which connector should I choose – JST-SM or xConnect®?
Choose the connector that matches your controller/extension system. For plug-and-play outdoor connections, xConnect® is typically the more robust option. JST-SM usually needs additional sealing and strain relief for outdoor use.
What should I check first if I see flicker?
1) common ground (GND) between controller/injection/string, 2) signal direction (DIN/DO), 3) voltage under load at the first and last pixel, 4) controller-to-first-pixel lead length (too long) / signal conditioning.
