Growlink LINKS M8 Extension Cable — 16ft 5in (5m) M8 Connector for ClimaLINK & TerraLINK Sensors

Position Sensors Wherever Accurate Data Actually Requires

A climate sensor is only useful if it sits at canopy level, and a substrate sensor is only useful if it reaches the actual root zone, but a sensor's built-in cable doesn't always reach that spot. The Growlink LINKS M8 Extension Cable adds 16ft 5in (5m) of reach for ClimaLINK and TerraLINK sensors, using a durable M8 connector so sensors can be placed exactly where representative data collection requires.

The cable is engineered to preserve signal integrity across its full length, and its rugged construction is built to handle the humidity and physical handling common in active grow spaces.

Key Features & Benefits

• 16ft 5in (5m) Extension: Adds meaningful reach for sensor placement across zones, canopy heights, or root depths.
• Durable M8 Connector: Maintains a secure connection in high-humidity grow environments.
• ClimaLINK & TerraLINK Compatible: Built specifically for Growlink M8-compatible sensors.
• Signal Integrity Preserved: Engineered to avoid data degradation across the full cable length.
• Built for Grow Environments: Rugged construction withstands humidity and routine handling.

Who Should Use This

Anyone placing ClimaLINK or TerraLINK sensors farther from a CanopyLINK hub than the sensor's built-in cable allows is the direct fit for this cable, especially in large rooms, multi-tier setups, or facilities routing cable cleanly around fixed equipment.

About Growlink

Growlink, founded in 2015, produces the cabling and connectivity accessories that extend its ClimaLINK and TerraLINK sensor hardware across larger cultivation facilities.

Frequently Asked Questions

Which sensors work with this cable?

It is compatible with Growlink ClimaLINK climate sensors, TerraLINK substrate sensors, and other Growlink LINKS devices using the M8 connector standard. Confirm your specific sensor uses an M8 connector before ordering.

Can multiple extension cables be chained together?

Multiple cables can be combined for greater reach, though excessively long total runs may start to affect signal quality. Check Growlink's documentation for the maximum recommended length for your specific sensor.

Does extending the cable reduce sensor accuracy?

No, the cable is engineered to maintain signal integrity across its full 5m length under normal operating conditions. Readings should transmit without noticeable degradation compared to using the sensor without an extension.

How is this different from the M8 Extension Cable Kit?

This is the cable alone. The M8 Extension Cable Kit (GLXGLM8EXTKIT) includes the same 5m cable plus a T-Connector and End Cap for splitting a sensor run or terminating a daisy-chain network.
