4-pin M12 twist-lock control cable for linking Matrix LED fixtures on a single signal run.
Matrix M12 Daisy Chain/A4 – 10ft (SKU: 10-010704-376) is the 4-pin A4-configuration control cable that runs fixture-to-fixture across Matrix LED systems, letting one controller signal drive an entire row of lights through M12 twist-lock connectors built for continuous grow-room operation.
The Matrix M12 Daisy Chain/A4 is a 4-pin control cable designed specifically for fixture-to-fixture linking within Matrix LED grow light systems. The A4 designation identifies a distinct pin configuration from the 3-pin A3 cable — it's not interchangeable, and using the wrong cable type on an A4 port will prevent the control signal from passing cleanly through the chain. If your Matrix fixtures require an A4 interface at that connection point, this is the correct cable.
At 10 feet, it's sized for overhead runs where fixtures are mounted in relatively tight proximity — typical of single-canopy commercial rooms, vertical rack bays, and multi-tier configurations where fixture centers are close together. For wider fixture spacing or longer inter-fixture gaps, Matrix also offers a 15ft version of the A4 cable.
Any licensed cannabis or hemp operator running a multi-fixture Matrix LED installation that relies on centralized control — dimming schedules, light intensity adjustments, photoperiod management — needs this cable to keep the control signal continuous across the row. One cable failure in the daisy chain breaks the signal to every fixture downstream, so having the correct Matrix-specified cable at each link in the run matters.
This cable is relevant whether you're building out a new room, expanding an existing one, or replacing a damaged or missing cable segment in an already-operating facility. It also applies to operators who manage multiple rooms and want uniformity in their control infrastructure across rooms that share the same Matrix LED fixture model.
M12 Twist-Lock Connectors: The M12 collar seats mechanically at both ends — twist to lock, twist to release. Unlike push-fit connectors, the mechanical seat holds through vibration, humidity swings, and the general movement of an active grow room. A cable that works loose mid-run means the fixtures downstream lose the control signal until someone finds and reseats it.
4-Pin A4 Configuration: The A4 wiring is purpose-built for the specific connection points in Matrix LED systems that require a 4-pin interface. Within the broader Matrix M12 cable ecosystem — which also includes A3, B3, B4, C3, and C4 variants — each type serves a defined role. The A4 is the daisy-chain link for fixtures with A4 ports; it is not a substitute for other cable types in the lineup.
Moisture-Resistant Build: The jacket and connector construction are rated for the condensation and high-humidity conditions standard in indoor cultivation environments. Standard cable materials degrade and corrode over repeated humidity cycles; the Matrix M12 cables are built to stay reliable in continuous-operation setups.
In a commercial row of Matrix LED fixtures, the daisy chain cable is what turns individual fixtures into a managed system. The control signal — dimming level, on/off schedule, intensity adjustments — originates at the controller and passes through each fixture in sequence via the daisy chain cables. Every cable in the run needs to match the correct configuration for that fixture's port, or the chain breaks at that link.
The 10ft A4 cable covers most tight-canopy overhead configurations where fixture centers are close. For facilities scaling from a single bay to a multi-room operation, having extra A4 cables on hand shortens the time between receiving new fixtures and getting them fully integrated into the control system. Order quantity should reflect your fixture count per row and the number of rows being controlled — one cable per inter-fixture gap, plus spares for maintenance.

The A3 is a 3-pin configuration and the A4 is a 4-pin configuration. They serve different connection points within the Matrix LED fixture lineup and are not interchangeable. Check which port your specific Matrix fixture model uses before ordering — using the wrong cable type at an A4 port will prevent the control signal from passing correctly.
The maximum daisy chain length depends on the specific Matrix fixture model in your installation. Matrix M Series LED fixtures have supported chains of up to 80 fixtures per run in documented configurations, but you should confirm the limit for your exact model with your Matrix documentation or by contacting HSC.
Measure the gap between your fixture mounting points — center to center — and add a few inches of service loop so the cable isn't under tension. If your fixture centers are 8 feet or less, the 10ft cable works cleanly. For wider spacing or longer inter-fixture gaps, the 15ft A4 version gives you the reach without splicing or adding extension cables.
No. Each cable type is specific to the port configuration on the fixture. A4 ports require A4 cables. If your installation has fixtures with different port types at different points in the chain, you need the correct cable type at each link — mixing them will result in a mismatch at the connector and break the signal.
Yes. Contact HSC for quantity pricing on cable orders tied to a larger fixture build. If you're speccing out a full room or multi-room installation, we can put together a complete cable list alongside the fixture order so everything arrives together.
