Matrix M12 to RJ12 Cable (B4): 4-Pin Controller Integration for Matrix LED Systems
The B4 steps up from the B3's 3-pin configuration to a 4-pin M12 connector on the fixture end — the additional pin carries the extra signal conductors that the RJ12 output side requires. RJ12 is the 6-conductor interface used on the Matrix MC5 controller's daisy-chain ports, which means this is the cable that connects Matrix LED fixtures into the MC5's channel scheduling, dimming, and spectrum control. The M12 locking collar seats mechanically on the fixture end, and that retention matters here specifically: a dropped connection to the controller pulls the whole channel offline, not just a single fixture.
RJ12 Output, Locking M12 Connection, and 10ft Reach for Matrix Controller Ports
At 10ft, the cable covers the typical run from a Matrix LED fixture to a wall- or rack-mounted MC5 controller without forcing extra slack through the overhead. The M12 B4 end seats into the fixture, the RJ12 end plugs directly into the controller port — no adapters, no custom wiring, no configuration. Moisture-resistant construction handles the humidity and temperature cycling of active grow rooms, where unrated jackets and contacts start degrading at the contact point long before the rest of the system shows wear.
Key Features
- M12 B4 (4-Pin) to RJ12 Connector Pairing: The 4-pin B4 configuration on the M12 end supports the additional conductors required by RJ12 controller ports — not interchangeable with the 3-pin B3 that terminates in RJ11.
- Matrix MC5 Controller Integration: RJ12 output plugs directly into the MC5's daisy-chain ports, putting each connected fixture inside the controller's scheduling, dimming, and per-channel spectrum management system.
- Twist-Lock M12 Connector on Fixture End: Mechanical locking keeps the 4-pin connection seated through vibration and humidity swings — a loose controller connection takes the entire downstream channel with it.
- Moisture-Resistant Construction: Jacket and contacts built for the continuous humidity and temperature cycling of indoor grow environments, where standard cable assemblies corrode at the contacts and degrade signal quality over time.
- 10ft Plug-and-Play Run: Spans the typical controller-to-fixture distance without adapters or termination work on either end — straightforward to install whether you're wiring one room or integrating across a larger Matrix LED setup.
