16' (4.88m) 4-Pins Waterproof Extension Cable

What the ECS-6 Does

The ECS-6 is a purpose-built 16-foot extension cable for TrolMaster's 4-pin waterproof connector system. Its primary job is to add reach — between a WCS-1 or WCS-2 moisture content sensor module and its sensor probe, or between compatible LED fixtures and Smart Light Lifters. The male-to-female design makes it a straight inline extension: connect the male end to the existing sensor or fixture cable, plug the female end into the module or next device in the chain, and the system reads it as a native connection.

The connectors are sealed for humid environments, rated to 90% relative humidity across a 32–122°F operating temperature range — appropriate for production grow rooms where irrigation, high VPD swings, and condensation are constant. No adapters, no signal converters, no driver installation required.

Who Needs It and When

Commercial and large-scale cultivation facilities running TrolMaster's Hydro-X or Hydro-X Pro environmental control systems regularly encounter a simple physical problem: the standard cable run between a sensor and its module isn't long enough to place the probe where accurate readings actually matter — at root zone depth, mid-canopy, or at a specific irrigation zone. The ECS-6 solves that without any re-wiring of the control system.

It's also the right solution when LED fixtures or Smart Light Lifters are mounted farther from a controller node than the stock cable allows. Multi-tier vertical grows, wide-bay greenhouse bays, and facilities with centralized controller cabinets mounted away from canopy are the most common use cases. Because the cable is rated for high humidity, it's equally at home in a propagation room, a flowering room, or a greenhouse bay with active misting.

Key Features

The ECS-6 adds exactly 16 feet of extension distance in a single cable, keeping cable management clean compared to splicing or daisy-chaining shorter cables. The 4-pin waterproof connectors use a threaded locking design that seats firmly and resists accidental disconnection — relevant in any facility with rolling benches, lift cables, or overhead equipment that can snag loose connections.

Installation is plug-and-play: no crimping, no configuration, no firmware. TrolMaster's Hydro-X system detects the connected sensor or device automatically once the cable is seated and locked. The cable ships in a compact package (156 mm × 83 mm × 30 mm) and carries a 1-year manufacturer warranty. For facilities needing multiple extensions or custom runs, TrolMaster's ECS-12 splitter cable and ECS-500 500 ft RJ12 cable roll are complementary accessories available through HSC.

How It Fits a Commercial Build

In a production environment, sensor placement precision directly affects irrigation accuracy and fixture control. A WCS-1 or WCS-2 moisture probe positioned imprecisely — because the cable wouldn't reach the target substrate zone — returns data that skews the entire irrigation schedule. One ECS-6 per zone corrects that without touching the controller configuration.

For operators standardizing on TrolMaster for environmental control across multiple rooms or facilities, stocking ECS-6 cables as a commissioning consumable is common practice. They're also a practical spare to have on-hand: a damaged or contaminated sensor cable mid-cycle can be swapped in minutes with a replacement already on site.
