However, it comes with a limitation that it can only be used in telephone handsets. This device can handle 4 wires simultaneously. The advantages of using Rj22 is that because the body of the device is made up of plastic, it is durable. These are used mainly in telephone handsets. Rj22 has copper pins that work as the conductor and are gold plated to avoid rusting. It also allows visibility of the connected wires to look through it. The purpose of these registered jacks is to connect the long-distance carrier to a voice or data equipment device. Rj11 is a registered jack that was invented in the United States in the 1970s. It cannot be used for heavy transmissions. It can only be used for telephone handsets. It has the capacity to hold 4 wires at the same time. It can hold 4 wires, while 6P2C can hold 2 wires at the same time. They are used in telephone lines and modems. Comparison Table Parameters of Comparison The copper pins are used as conductors and are plated with gold to prevent rusting. It also has a capacity of holding 4 wires at the same time but unfortunately has limited use. The Rj22 port is used in telephone handsets. Rj22 is not a registered jack but unofficially is a part of it. Keep in mind that some lights have an 'in' and 'out' RJ style connector, so you may not need to use splitters.Rj22 comes with a configuration of 4P4C which means 4 Positions and 4 Connectors. We recommend using GrowFlux's daisy chain cables from our Universal Dimmer product family - this way most of your wiring will be waterproof, your installation will be future proof when you eventually upgrade your lights, and you will benefit from more robust cabling which uses UV resistant, UL rated 22AWG cables for runs up to 200 feet.Īlternatively, RJ style splitters and RJ cables can be used to daisy chain the signal to multiple lights (not available from GrowFlux). How to daisy chain a dimming signal to multiple lights We recommend always wiring all four positions, this way if only two positions are connected inside your light, you will still have a dimming connection.ģ. Note that there are two pins for dim+ and dim- respectively. The pinout for a typical RJ9, RJ11, RJ12, or RJ14 connector is shown below along with the pin assignments. LED lighting brands that have used RJ style connectors at some point include Horticulture Lighting Group, Luxx, Mammoth Lighting, Spider Farmer, and Upowertek. Visually check your light for the connector type as the product documentation for many legacy lights is hard to obtain. In some cases, lights have been updated to remove the RJ connector and replace them with a sealed connector. HPS lights that use RJ style connectors include Hydrofarm, Phantom, Dimlux, Luxx, Iluminar, and Gavita. Which brands use RJ11, RJ12, or RJ14 connectors? We have tested dozens of grow lights (LED, HPS, and CMH) over the last decade and haven't encountered one that needs all six wires. As a result, we have designed the RJ Adapter to mate to any grow light using one of the below RJ style connectors. Mechanically, all of these connectors can inter-mate, even though some have a different number of contacts and positions. We'll focus only on the ones commonly used for dimming grow lights. There are many different types of RJ style connectors. What is the difference between RJ11, RJ12, RJ14, etc? This article breaks down all of your RJ connector questions.ġ. There is no official industry standard around the use of these connectors or the specific connector to be used, and there is little information around compatibility across the various brands that use this style connector. These connectors are convenient because RJ style splitters and cables are widely available and economical, however these connectors are not waterproof and may not offer the best reliability in a commercial setting. Many legacy HPS lights, older LED grow lights, and even some of the latest non-waterproof LED lights from top brands use Registered Jack (RJ) style connectors for 0-10V dimming signaling.
