TrolMaster 4-Pin Waterproof Extension Cable 16 ft for WCS-1 and WCS-2 (ECS-6)

TrolMaster 4-Pin Waterproof Extension Cable for Substrate Probes

Substrate probes rarely sit where the sensor module wants them, and this lead covers the gap. The ECS-6 is a 16 ft extension with a 4-pin male plug on one end and a matching female socket on the other. Both ends are waterproof, which matters on a lead that runs across benches, past drip lines and under runoff trays. It extends the link between a WCS-1 or WCS-2 water content sensor module and its probe. It is also compatible with ThinkGrow LED fixtures and Smart Light Lifters. The working range is 32 to 122°F at up to 90% humidity. The package measures 156 x 83 x 30 mm and ships at 0.29 lb. It plugs in without tools or splicing. That length reaches from a wall-mounted module to the middle of most benches. TrolMaster covers it with a three-year warranty.

Placing a WCS-1 Water Content Sensor Where the Readings Count

In a WCS install, the probe belongs in the root zone of a representative plant, not the wettest or driest pot in the room. The module stays somewhere dry and reachable, and this cable spans the distance between the two. Choosing the plant by its position, rather than by how close it sits to the module, gives readings that match the room. Lay the cable along the bench edge and clip it in place, so watering and pot moves leave the probe in place. Seat each waterproof joint fully and keep it off the floor, where standing water collects after irrigation. On ThinkGrow fixtures and Smart Light Lifters, the extension adds slack where the stock lead runs short of the controller. A loose plug shows up as missing readings, which is easy to mistake for a failed probe. The limit worth knowing is that this is a cable, not a hub. One lead joins one device, so each extra probe or fixture needs its own extension. The readings themselves still come from the probe at the far end.

Key Features

• 16 ft Waterproof Run: Both connectors are waterproof, so the lead can cross wet benches between the module and the probe.
• 4-Pin Male to Female: It plugs in line with the stock probe or fixture lead without tools.
• WCS-1 and WCS-2 Compatible: It extends either TrolMaster water content sensor module to its probe.
• ThinkGrow and Light Lifter Fit: The same cable extends ThinkGrow LED fixtures and Smart Light Lifters.
• Wide Working Range: It is rated for 32 to 122°F at up to 90% humidity.
