Zodiac – BNC connector extension 3m – R0635800

The Zodiac BNC connector extension 3m (R0635800) is a genuine replacement accessory designed to extend the cable connection between a BNC-type probe and its compatible Zodiac pool control unit. This extension cable measures 3 metres in length and uses a standard BNC (Bayonet Neill–Concelman) connector interface, ensuring a reliable, secure, and interference-resistant signal connection between the probe and the controller. It is an official Zodiac spare part, manufactured to the same quality standards as the original equipment it replaces.

The BNC connector type is widely used in instrumentation and measurement applications due to its dependable locking mechanism and excellent signal integrity. This makes it particularly well suited for sensitive electrochemical probes such as pH and ORP (redox) sensors, where accurate and stable signal transmission is critical for correct water treatment control. The 3-metre cable length provides practical flexibility for installations where the probe mounting point is at a distance from the control unit, without introducing unnecessary signal degradation.

Technical characteristics and compatibility

This extension is specifically referenced for use with Zodiac probe type Z54, which is employed across several Zodiac water treatment systems. Confirmed compatible systems include the Zodiac Tri pH, Tri Pro, pH Link, Dual Link, and related electrolysis and pH control platforms. The cable is designed to maintain the integrity of the low-level analogue signal generated by the probe, ensuring that the readings passed to the controller are accurate and free from interference. The BNC bayonet locking connector provides a firm, vibration-resistant connection that will not loosen over time under normal pool plant room conditions.

As an official Zodiac OEM spare part carrying reference R0635800, this extension is the correct replacement component to use when the original cable has become damaged, corroded, or too short for a modified installation layout. Using a genuine Zodiac part ensures full electrical and mechanical compatibility with the parent system and does not risk voiding any warranty coverage associated with the control unit or probes.

Suitability and intended application

This product is intended for pool owners and installers working with Zodiac automated water treatment systems that use Z54-type BNC probes. It is suitable for both residential and light commercial pool installations where Zodiac Tri pH, Tri Pro, pH Link, or Dual Link systems are deployed. It is a maintenance or replacement part rather than a component sold with new installations, making it the correct choice when an existing probe cable needs to be replaced or when an installation requires the probe to be positioned further from the control unit than the original cable allows. No specialist tools are required beyond a standard BNC push-and-twist connection, making installation straightforward for a qualified pool technician.
