IP67-rated RJ12 extension built for sealed, high-humidity cultivation environments.
Faven's 15-foot Double-Sided Watertight RJ12 Cable (SKU 10-010508-003) extends communication runs between under-canopy fixtures inside sealed grow environments. Both ends feature screw-on watertight connectors rated IP67 — fully dust-tight and protected against temporary immersion — so the signal line stays clean and corrosion-free regardless of irrigation spray or condensation.
This is a purpose-built RJ12 communication extension cable for Faven under-canopy lighting systems operating inside sealed, wet-environment grow rooms. At 15 feet (4.5 meters), it is the longest cable in Faven's watertight communication lineup — the other options are a 12-inch double-end jumper and a 10-foot single-end cord. The double-sided designation means both ends carry the same screw-on watertight connector, making this cable appropriate for mid-run extensions between fixtures or between a fixture and a watertight T-splitter.
The connector standard is RJ12 — a 6-position, 6-conductor (6P6C) format commonly used for dimming and signal communication on commercial horticultural lighting. The screw-on collar on each connector engages mechanically with mating ports on Faven power cords and watertight T-splitters, creating a sealed interface rather than a friction-fit plug. This design prevents the cable from backing out under vibration and blocks moisture ingress at the connection point itself, not just along the cable jacket.
IP67 is defined under IEC standard 60529. The first digit — 6 — indicates complete dust-tight protection: no particulate ingress under any test condition. The second digit — 7 — indicates the assembly can withstand temporary immersion in water up to 1 meter deep for up to 30 minutes without damage. In a grow room context, that threshold far exceeds what the cable will encounter: overhead irrigation overspray, dripper runoff, floor wash-down, and high-humidity condensation all fall well within IP67 tolerance.
Where IP66-rated fixtures protect against direct water jets from any direction, IP67 goes one step further by certifying temporary submersion resistance. For cultivation operators running aggressive irrigation schedules or overhead fertigation, that additional margin matters. The watertight screw-on connectors carry the same rating as the cable jacket, so the IP67 protection applies to the system as assembled — not just the cable in isolation.
Faven's under-canopy lighting system is designed as a modular daisy-chain architecture. Each bench requires at least one power cord; additional fixtures in the row are linked via communication cables. The 15-foot double-sided cable is the right choice when fixtures are spaced farther apart along a bench row, when routing around obstacles requires extra length, or when connecting across two adjacent rows on a wider bench. It plugs directly into the female communication port on Faven power cords and into any Faven watertight T-splitter.
The cable also supports runs that branch through T-splitters — each splitter allows two sets of fixtures to be connected into a single RJ12 communication line, enabling more complex bench layouts without additional power cords. For operators who need to terminate a run into a 0-10V control panel rather than another fixture, the separate RJ12-to-screw-terminal adapter (sold separately) picks up where this cable leaves off. The 15-foot length is specific to double-sided configurations; single-end versions (used where one end terminates at a power cord's female port) are available in 10-foot length.
This cable is part of Faven's sealed communication accessory line, which includes watertight T-splitters, screw-terminal adapters, and rubber end caps for open ports. It is designed exclusively for use with Faven under-canopy bar fixtures and Faven power cords — it is not a general-purpose RJ12 telephone or data cable and should not be substituted into non-Faven lighting systems without verifying connector compatibility.
For commercial operators building multi-bench or multi-zone Faven installations, cable quantity planning is straightforward: count the number of inter-fixture gaps that exceed what the fixture's integrated cord length covers, and order accordingly. Faven's lighting system supports daisy-chaining up to 20 fixtures per power cord at 120V configurations; operators running larger benches will need multiple power cords and may need multiple 15-foot extension cables depending on row length and fixture spacing.

A double-sided cable has watertight screw-on connectors on both ends. It is used to extend a communication run between two fixtures or between a fixture and a T-splitter — anywhere both connection points are within the sealed system. A single-end cable has a watertight connector on one end and a standard RJ12 plug on the other; that non-sealed end is typically used where it terminates at a protected port inside a fixture or power cord housing rather than in an open wet zone.
The number depends on your bench length, fixture count, and how many fixtures are spaced farther apart than the integrated cable length covers. Each gap between fixtures that exceeds the built-in cord reach needs one extension cable. If your bench has multiple rows, you may also need a cable to connect across rows through a T-splitter. HSC can help you plan exact cable quantities as part of a full system quote — reach out with your bench dimensions and fixture count.
This cable is a communication extension within the Faven fixture-to-fixture signal run. Faven's under-canopy lighting system is compatible with TrolMaster and Vivosun dimming controllers, but the interface between the Faven system and a third-party controller typically uses a separate adapter (such as the RJ12-to-screw-terminal adapter) rather than this extension cable. This cable's role is to extend the RJ12 run between Faven fixtures and Faven accessories — not to bridge into external controller systems directly.
IP67 is an ingress protection rating defined under IEC 60529. The '6' means the connector is completely dust-tight; the '7' means it can withstand temporary immersion in water up to 1 meter deep for 30 minutes. In a grow room, overhead irrigation spray, fertigation runoff, and floor wash-down are routine — a standard RJ12 cable with friction-fit connectors would corrode and fail signal continuity over time. The screw-on watertight connectors on this cable maintain the IP67 seal at the connection point, protecting the signal line as long as both ends are properly mated.
No. Cable length and fixture count are separate constraints. This cable extends the physical distance between fixtures within a single daisy-chain run, but it does not increase the maximum number of fixtures you can run per power cord. Faven's system supports up to 20 fixtures per power cord at standard 120V configurations. If your fixture count exceeds the daisy-chain limit, you need an additional power cord — adding a longer communication cable alone will not resolve an over-limit run.
