Quick and Flexible Connection of Dynamic Lighting with Wieland

Dimmable and spectrum-controlled LED lighting is rapidly gaining popularity in greenhouse horticulture due to its adjustable energy consumption and impact on energy contract costs. Dimming is becoming the standard. Countries like Canada, the Netherlands, and Scandinavia have already included this requirement in their subsidy schemes, or are planning to do so, and other countries are expected to follow soon.

Wieland Connectors

In the coming years, a rise in three- and four-channel luminaires is expected. Variable spectrum lighting, controlled by algorithms and intelligent plant sensors, will increase the demand for multi-pole connectors.

Advantages of 4- to 7-pole Wieland Connectors

When using dimmable and 3- or 4-channel luminaires, 4-, 5-, 6-, or 7-pole Wieland RST20^® connectors are a smart and future-proof choice. These connectors not only offer more connection options, but also ensure reliability, flexibility, and safety in every professional lighting installation, as proven for many years in greenhouse horticulture.

1. More functionality with fewer cables
One of the biggest advantages is that a single cable can carry multiple signals or power lines. For 3- or 4-channel luminaires, such as RGB or RGBW, separate lines are needed for each color or function. With a 4-, 5-, 6-, or 7-pole connector, all these lines can be connected efficiently and neatly, without creating a spaghetti of loose cables.

2. Reliability and safety
Wieland connectors are robust, mechanically strong, and resistant to moisture, dust, and other external influences; ideal for intensive use in horticultural installations. Fewer loose connections also mean fewer chances of faults or signal loss.

3. Fast installation and disassembly
Thanks to standardized pin layouts and locking mechanisms, Wieland RST20 ^® connectors can be connected quickly and safely, drastically reducing installation time and preventing errors.

4. Waterproof
Just like the well-known 3-pole RST20 ^® series, these multi-pole versions are now also available in a design that is not only waterproof from the outside, but also features an internal water stop. A longitudinal seal on the contacts ensures that moisture from a cable cannot enter the luminaire through the connector.

In short, Wieland RST20^® 4-, 5-, 6-, and 7-pole connectors are not only the technically correct choice for dimmable and multi-channel luminaires, but also an investment in efficiency, durability, and professional quality.
They offer the flexibility and reliability every luminaire needs.
