IP67-sealed RJ12 T-splitter purpose-built for wet commercial grow environments.
The Faven Watertight RJ12 T Splitter takes a single RJ12 communication line and branches it into two outputs, letting you connect two fixture runs to one controller port without compromising signal integrity. IP67-rated sealed housing protects internal contacts from spray, humidity, and corrosion — the failure points that expose standard splitters in a commercial grow.
The Faven Watertight RJ12 T Splitter is a purpose-built communication accessory for Faven under-canopy lighting systems. It accepts one RJ12 6P6C input and splits the signal into two output ports, allowing two sets of fixtures to share a single communication line back to the controller. The T-configuration keeps cable runs organized and reduces the total number of controller ports required when daisy-chaining multiple lighting zones together.
The connector format is RJ12 6P6C — a 6-position, 6-conductor modular connector that carries all communication signals needed for Faven fixture dimming and control. This is distinct from the physically similar but electrically limited RJ11 (4-conductor) format; using the full 6P6C spec ensures no signal paths are lost through the split.
Standard RJ12 splitters are not rated for wet environments. In a commercial cannabis or hemp facility, communication cables are routinely exposed to irrigation overspray, IPM application, pressure washing, and sustained high-humidity conditions. A non-sealed connector body will corrode at the contact points over time, causing intermittent signal loss, dropped dimming commands, or complete communication failure between fixtures and the controller.
Faven's watertight housing addresses this directly. The IP67 ingress protection rating means the splitter is sealed against dust ingress (6) and against temporary water immersion up to 1 meter for 30 minutes (7) — well above what a normal grow environment will throw at it. The sealed housing protects the internal contacts and keeps the communication line stable long-term without requiring periodic inspection or contact cleaning.
Faven under-canopy lighting systems are designed around daisy-chained communication runs using RJ12 watertight cabling. The T Splitter is the junction point that lets a single controller output feed two independent fixture runs simultaneously — useful when your canopy layout requires branching across benches, rows, or zones that don't follow a straight daisy-chain path.
It mates directly with Faven's watertight RJ12 communication cables, which use screw-on connectors at each end for a secure, sealed connection. When building or expanding a lighting communication network, this splitter is the correct component to branch a run without introducing open, unsealed junction points. It pairs with Faven's double-sided watertight RJ12 cords, single-sided extension cords, and the screw-terminal adapter for 0-10V panel integration.
This splitter is sold as an individual unit and is the correct component any time a Faven communication run needs to branch into two outputs — whether that's splitting across two benches, combining two fixture groups onto one controller zone, or cleaning up a cable layout that has grown through facility expansion. It is not a signal amplifier; both output branches carry the same signal from the single input, consistent with how the Faven system is designed to operate.

The connector format — RJ12 6P6C — is a standard modular connector type. However, this splitter is built and rated to integrate with Faven's watertight communication cable ecosystem, where the screw-on sealed connectors require a housing designed to mate with them. It is specifically recommended for use within Faven under-canopy lighting builds. Compatibility with other brands' RJ12 systems should be confirmed before purchase.
No. In a passive RJ12 T splitter, both output ports carry the same signal as the input — the signal is not divided or attenuated between the two branches. This is consistent with how Faven's system is designed to operate when branching fixture communication runs from a single controller output.
IP67 means the enclosure is fully dust-tight (rated 6) and sealed against temporary water immersion up to 1 meter for 30 minutes (rated 7). For typical commercial grow room conditions — irrigation overspray, foliar application, high ambient humidity — IP67 provides a robust level of protection. For direct, sustained high-pressure spray cleaning, confirm the specific spray pressure and duration against the rating before exposing the connector.
This splitter is designed to mate with Faven's watertight RJ12 communication cables, which use screw-on sealed connectors on one or both ends. Available lengths include 1-foot, 10-foot, and 15-foot options in single- and double-sided configurations. If you're building a new run or extending an existing one, request a quote and we can help confirm which cable lengths and quantities fit your layout.
The T Splitter itself is not a protocol converter — it branches the RJ12 communication line, not convert it. For 0-10V panel integration, Faven makes a separate RJ12-to-screw-terminal adapter that connects an RJ12 communication port to bare wire for analog 0-10V control. The T Splitter would be used upstream of that adapter if you need to branch the run before the panel connection point.
